Converting strings to numbers in JavaScript
 
17:14
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/11/converting-strings-to-numbers-in.html In this video we will discuss different methods that are available in JavaScript to convert strings to numbers. This example allows the user to enter 2 numbers and add them. Along the way we will learn the use of the following functions 1. parseInt() 2. parseFloat() 3. isNan() Here is the HTML for the web form [table style="border:1px solid black; font-family:Arial"] [tr] [td]First Number[/td] [td][asp:TextBox ID="txtFirstNumber" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Second Number[/td] [td][asp:TextBox ID="txtSecondNumber" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Result[/td] [td][asp:TextBox ID="txtResult" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td] [/td] [td] [input type="button" value="Add" id="btnAdd"/] [/td] [/tr] [/table] Include the following JavaScript in the head section of the web form. [script type="text/javascript"] function addNumbers() { var firstNumber = document.getElementById("txtFirstNumber").value; var secondNumber = document.getElementById("txtSecondNumber").value; document.getElementById("txtResult").value = firstNumber + secondNumber; } [/script] Set the onclick attribute of the Add button to call the addNumbers() function. The HTML for the button should be as shown below. [input type="button" value="Add" id="btnAdd" onclick="addNumbers()" /] Run the application and enter 20 as the first number and 10 as the second number. Click Add buton. Notice that JavaScript concatenates the numbers instead of adding them. This is because the value property of the textbox is returning the number in a string format. So we need to explicitly do the conversion. This is when parseInt() function is useful. Modify the addNumbers() JavaScript function as shown below. function addNumbers() { var firstNumber = parseInt(document.getElementById("txtFirstNumber").value); var secondNumber = parseInt(document.getElementById("txtSecondNumber").value); document.getElementById("txtResult").value = firstNumber + secondNumber; } Run the application and test. Notice that we now get 30 as expected. Let's do another test. Enter 20.5 as the first number and 10.3 as the second number. Click the Add button. Notice that the decimal part is ignored. To retain the decimal places, use parseFloat() function. function addNumbers() { var firstNumber = parseFloat(document.getElementById("txtFirstNumber").value); var secondNumber = parseFloat(document.getElementById("txtSecondNumber").value); document.getElementById("txtResult").value = firstNumber + secondNumber; } If you leave first number and second number textboxes blank or if you enter text instead of a number, and when you click the Add button, NaN is displayed in result textbox. NaN in JavaScript stands for Not-a-Number. In JavaScript we have isNaN() function which determines whether a value is an illegal number. This function returns true if the value is not a number, and false if not. Modify the addNumbers() JavaScript function as shown below. function addNumbers() { var firstNumber = parseFloat(document.getElementById("txtFirstNumber").value); if (isNaN(firstNumber)) { alert("Please enter a valid number in the first number textbox"); return; } var secondNumber = parseFloat(document.getElementById("txtSecondNumber").value); if (isNaN(secondNumber)) { alert("Please enter a valid number in the second number textbox"); return; } document.getElementById("txtResult").value = firstNumber + secondNumber; } Now, when you leave first number and second number textboxes blank or if you enter text instead of a number, and when you click the Add button, you get relevant validation error messages as expected. Let's make the validation error message a little more relevant: If the first number and second number textboxes are left blank, then we want to display the following validation messages a) First Number is required b) Second Number is required If you enter text instead of number a) Please enter a valid number in the first number textbox b) Please enter a valid number in the second number textbox

Javascript Tutorial with Examples For Beginners (pt 1)
 
04:21
This is part one of a series of javascript programming tutorials for beginners. I've created a bunch of example and sample problems for you to solve here: http://www.pyaraapp.com/js-tutorial-1.html Go to that site, open the developer console and type in the following commands and see what happens: /* Javascript Can Change HTML Content */ document.getElementById("demo").innerHTML = "Hello There"; /* JavaScript Can Change HTML Styles (CSS) */ document.getElementById("demo").style.fontSize = "30px"; /* JavaScript Can Hide HTML Elements */ document.getElementById("demo").style.display="none"; /* JavaScript Can Show HTML Elements */ document.getElementById("demo").style.display="block"; The problem with most javascript tutorials is that they don't give you enough example problems. If you are a beginner, it is really hard to learn how to code by just watching videos. You need to go out there and really solve sample problems. What is javascript: JavaScript is the programming language of HTML and the Web. Programming makes computers do what you want them to do. JavaScript is easy to learn. This tutorial series will take you from a JavaScript beginner to an expert. Why Study JavaScript? JavaScript is one of the 3 languages all web developers must learn: 1. HTML to define the content of web pages 2. CSS to specify the layout of web pages 3. JavaScript to program the behavior of web pages This tutorial is about JavaScript, and how JavaScript works with HTML and CSS. Learn by Examples: Examples are better than 1000 words. Examples are often easier to understand than text explanations. This tutorial supplements all explanations with clarifying "Try it Yourself" examples. If you try all the examples, you will learn a lot about JavaScript, in a very short time! In this video, I will use the javascript console thats built into the chrome developer tools to get you to start writing javascript code. With the chrome browser, you will be able to write out some code and see the results immediately. Then I will show you how to store a variable and what a variable really is. Then I will go over the different types of variables and then how to output the values of these variables you created.

In JavaScript, the 'querySelectorAll' method allows you to retrieve a list of Elements that match the CSS Selector that you specify. Essentially, it is a way of finding Elements in JavaScript. It's quitee flexible and lets you search for tags, classes, IDs, parent/child combinations, attributes and so on. In this video I show you a clear and simple example of how it works on the 'document' object as well as another Parent Node - to only search within that parent.

My Personal JavaScript Notes on How to
 
05:30
MyWebSite: https://www.aimiecaprice.com How to store an HTML elements content into a variable. How to write content to a variable using JavaScript. How to run a comparison statement on an HTML elements content When I initially dove into this, creating the condition was the thing that stumped me most. I got the rest of the equation that stated if this condition exists, do xyz. But my problem came with how do you get JavaScript to check if the condition exist and how do you create condition? Actually creating the condition is what really stump me most probably because I was over thinking it. I knew I wanted JavaScript to change the CSS display property depending on what image a user clicked...so I needed to write a function, make the image clickable, and have the function fire off "OnClick" So I created the condition inside the function which meant every time that function fired off the condition would be created by the function. JavaScript would literally write code that stated var x = 1, or var x = 2, depending on which function was being called by the user clicking various different images. . Example var x = 1; if( x == 1) { document.getElementById("desTxt1").style.display = "inline-block"; document.getElementById("desTxt2").style.display = "none"; document.getElementById("desTxt3").style.display = "none"; document.getElementById("desTxt4").style.display = "none"; document.getElementById("desTxt5").style.display = "none"; document.getElementById("desTxt6").style.display = "none"; document.getElementById("desTxt7").style.display = "none"; document.getElementById("desTxt8").style.display = "none"; document.getElementById("desTxt9").style.display = "none"; document.getElementById("desTxt10").style.display = "none"; document.getElementById("desTxt11").style.display = "none"; document.getElementById("desTxt12").style.display = "none"; }

Assigning event handlers in JavaScript using DOM object property
 
10:20
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/assigning-event-handlers-in-javascript.html In JavaScript there are several ways to associate an event handler to the event. In Part 36, we discussed, associating event handler methods to events using the attributes of HTML tags. In this video we will discuss using DOM object property to assign event handlers to events. First let us understand, what is DOM DOM stands for Document Object Model. When a browser loads a web page, the browser creates a Document Object Model of that page. The HTML DOM is created as a tree of Objects. Example : [html] [head] [title]My Page Title[/title] [/head] [body] [script type="text/javascript"] [/script] [div] [h1]This is browser DOM[/h1] [/div] [/body] [/html] JavaScript can be used to access and modify these DOM objects and their properties. For example, you can add, modify and remove HTML elements and their attributes. Along the same lines, you can use DOM object properties to assign event handlers to events. We will discuss the DOM object in detail in a later video session. We will continue with the same examples that we worked with in Part 36. Notice that in this case, we are assigning event handlers using the DOM object properties (onmouseover & onmouseout) instead of using the attributes of the HTML tag. We are using this keyword to reference the current HTML element. In this example "this" references the button control. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onmouseover = changeColorOnMouseOver; document.getElementById("btn").onmouseout = changeColorOnMouseOut; function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] The following example is same as the above. In this case we are assigning an anonymous function to onmouseover & onmouseout properties. [input type="button" value="Click me" id="btn" /] [script type="text/javascript"] document.getElementById("btn").onmouseover = function () { this.style.background = 'red'; this.style.color = 'yellow'; } document.getElementById("btn").onmouseout = function () { this.style.background = 'black'; this.style.color = 'white'; } [/script] If an event handler is assigned using both, i.e an HTML attribute and DOM object property, the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute. Here is an example. [input type="button" value="Click me" id="btn" onclick="clickHandler1()"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler set using HTML attribute"); } function clickHandler2() { alert("Handler set using DOM object property"); } [/script] Using this approach you can only assign one event handler method to a given event. The handler that is assigned last wins. In the following example, Handler2() is assigned after Handler1. So Handler2() owerites Handler1(). [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler1; document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script]

Where should the script tag be placed in html
 
09:40
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/11/where-should-script-tag-be-placed-in.html In this video we will discuss, where should the script tag be placed in the html. Should it be placed in the body or head section of the page. In general the script tag can be placed either in the head or body section. Let's look at a few examples : Example 1 : Script tag in the head section [html] [head] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/head] [body] [form id="form1" runat="server"] [/form] [/body] [/html] Example 2 : Script tag in the body section [html] [head] [/head] [body] [form id="form1" runat="server"] [/form] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/body] [/html] In Example 1 we placed the script tag in the head section and in Example 2, we placed it in body section. In both the cases JavaScript works as expected. Example 3 : Sets the background color of the TextBox to red. [html] [head] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/body] [/html] Example 4 : This is same as Example 3, except we moved the script tag to the head section. In this case the script will not work as expected. Depending on the browser you are using you get one of the following JavaScript error. Firefox - TypeError: document.getElementById(...) is null Chrome - Uncaught TypeError: Cannot read property 'style' of null IE - Unable to get property 'style' of undefined or null reference To see these JavaScript errors press F12 which launches developer tools. F12 works for all the 3 browsers. [html] [head] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [/body] [/html] Why did the JavaScript did not work in this case JavaScript code is present before the textbox control. By the time the JavaScript code is executed, the textbox is still not loaded into browser DOM (Document Object Model). This is the reason JavaScript can't find the textbox and throws a NULL reference error. In Part 6, we discussed that, in general it is a good practice to store JavaScript in an external .js file. So, if the JavaScript is present in an external file and if you are referencing it on a page using [script] element, where should such [script] element be placed. To answer this question, first let's understand what happens when a browser starts loading a web page. 1. The browser starts parsing the HTML 2. When the parser encounters a [script] tag that references an external JavaScript file. The parser stops parsing the HTML and the browser makes a request to download the script file. Until the download is complete, the parser is blocked from parsing the rest of the HTML on the page. 3. When the download is complete, that's when the parser will resume to parse the rest of the HTML. This means the page loading is stopped until all the scripts are loaded which affects user experience. In general, the suggested good practice is to place the [script] tag just before the closing [body] tag, so it doesn't block the HTML parser. However, modern browsers support async and defer attributes on scripts. These attributes tell the browser it's safe to continue parsing while the scripts are being downloaded. But even with these attributes, from a performance standpoint it is still better to place [script] tag just before closing [body] tag. According to HTTP/1.1 specification browsers download no more than two components in parallel. So, if the page has several images to download and if you place [script] tags at the top of the page, the script files start to download first which blocks the images download which adds to the total page load time.

JavaScript for getElementById
 
02:34
Introduction JavaScript JavaScript is a scripting or programming language that allows you to implement complex things on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. • HTML is the markup language that we use to structure and give meaning to our web content, for example defining paragraphs, headings, and data tables, or embedding images and videos in the page. • CSS is a language of style rules that we use to apply styling to our HTML content, for example setting background colors and fonts, and laying out our content in multiple columns. • JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. (Okay, not everything, but it is amazing what you can achieve with a few lines of JavaScript code.) Before You Starting JavaScript You should know basic HTML and CSS

Events in JavaScript

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

jQuery #id selector
 
10:53
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/jquery-id-selector.html In this video we will discuss 1. What are jQuery selectors 2. Different selectors in jQuery 3. #id selector in jquery What are jQuery selectors One of the most important concept in jQuery is selectors. jQuery selectors allow you to select and manipulate HTML elements. Different selectors in jQuery jQuery selectors allow you to select html elements in the DOM by 1. Element ID 2. Element Tag Name 3. Element Class Name 4. Element attribute 5. Element Attribute values and many more Id selector in jquery To find an HTML element by ID, use the jQuery #id selector Example : The following example finds button with ID button1 and attaches the click event handler. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').click(function () { alert('jQuery Tuorial'); }); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] Changes the background colour of the button to yellow $(document).ready(function () { $('#button1').css('background-color', 'yellow'); }); Important points to remember about jQuery #id selector 1. jQuery #id selector uses the JavaScript document.getElementById() function 2. jQuery #id selector is the most efficient among all jQuery selectors. If you know the id of an element that you want to find, then always use the #id selector. 3. HTML element IDs must be unique on the page. jQuery #id selector returns only the first element, if you have 2 or more elements with the same ID. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').css('background-Color', 'yellow'); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [input id="button1" type="button" value="Click Button" /] [/body] [/html] 4. JavaScript's document.getElementById() function throws an error if the element with the given id is not found, where as jQuery #id selector will not throw an error. To check if an element is returned by the #id selector use length property. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { if ($('#button1').length ] 0) { alert('Element found') } else { alert('Element not found') } }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] 5. JavaScript's document.getElementById() and jQuery(#id) selector are not the same. document.getElementById() returns a raw DOM object where as jQuery('#id') selector returns a jQuery object that wraps the DOM object and provides jQuery methods. This is the reason you are able to call jQuery methods like css(), click() on the object returned by jQuery. To get the underlying DOM object from a jQuery object write $('#id')[0] 6. document.getElementById() is faster than jQuery('#id') selector. Use document.getElementById() over jQuery('#id') selector unless you need the extra functionality provided by the jQuery object.

A 10-minute very complete introduction to DOM(Document Object Model) with Javascript
 
12:48
This video discusses a very beginer's introduction on DOM. The audio is generated by a computer software using TTS so it might not be very natural, but it should server the purpose This video is one of our classroom series. It will need to be followed up by trainer attended exercises. Please join our classroom at Kharar, Sector 127, Mohali, INDIA Our webiste is http://www.hoven.in or http://www.hoventrainings.com Transcription ========== what is DOM and how to use javascript for manipulating DOM on every HTML page we have seen so many tags - DIV tag, SPAN tag, BODY tag and so on The DOM model looks at them from an object oriented perspective and calls them objects more specifically, these are called DOM Elements let's look at this page from the angle of DOM this is an element this is an element as well this too every tag is an element let me draw a hierarchical chart the html page contains a head tag which has a child called title tag more could be there, like meta tags body tag is an immediate child of the html element it contains a DIV could contain more tags, like IMG, SPAN similarly, this DIV could be a container html root element head and body all elements in a DOM hierarchy are interlinked wandering orphans are not possible a tag would be either a parent of some or a child of some a DOM is a hierarchical tree let's have a look at the structure of an element this is the opening tag it closes here this is an attribute called ID. If specified, it should be a unique identifier. this is another attribute yet another the attributes like id, class, style are pre-defined ones but you can define your own tags also. you should start them with data- these are the values for attributes and this is called inner html or text to summarize, each DOM element has a unique id a DOM element can have attributes the content of an element is called its inner HTML let me show you the inner html this is the inner html in this DIV tag ID and custom data attributes can be seen inner html attributes can be classified. ID is a special attribute then, there are pre-define standard ones there could be custom attributes these look like data followed by a hyphen events and their handlers are also specified as attributes the are DOM objects the HTML Document is a DOM object the browser window too is one DIV, SPAN, etc., all are as well each DOM object is different it has its own list of properties, events and functionality each object has its own documentation, clearly laid down in the DOM standard there are a number of additional documented functions that could be used to manipulate an element these all are together called the DOM API we have properties functions or methods events let me explain this with the help of a concrete example "document" is a DOM element it has a property called styleSheets that can be used to get the list of the included CSS files likewise, it has a title property then it has a function called getElementById and it also an event the list is too large to include here we'll now see DOM API at work we shall write javascript here the above div is a part of the document so we can use getElementById to obtain a reference to it we can read the innerHTML property and display it as expected! you can use DOM API for programmatically altering an HTML document add, remove, modify these are the ones we use more commonly create an element read html read or write attributes change css attach events Of course, jQuery makes these tasks even easier, thank you

Белые тигрята в японском зоопарке повеселили посетителей. Белые тигрята я японском зоопарке, которые появились на свет в конце января, показались публике. И сделали это эффектно, устроив своеобразное представление. Забавная спасательная операция развернулась в японском зоопарке Тобу, что в окрестностях Токио. Два белых тигрёнка решили, что их брат не сможет самостоятельно выбраться из мини-бассейна, и пришли ему на выручку, сообщает ТВ Центр. При этом утопающий отчаянно сопротивлялся, а его крики были слышны посетителям через толстое стекло вольера. К тому моменту, когда на помощь подоспели мама-тигрица и ещё один тигрёнок, полосатым спасателям уже удалось вытащить брата на сушу. Сразу четыре детёныша редчайших белых тигров появились на свет в конце января и пока не получили клички. В мае среди посетителей проведут конкурс на лучшие имена для новых питомцев зоопарка.

Change gridview row color when checkbox is checked

We want to achieve this using JavaScript. The background color of the rows that are select should be grey, and the rows that are not selected should be white. We will continue with the example that we worked with in Part 3 of JavaScript with ASP.NET tutorial. Modify HeaderCheckBoxClick() and ChildCheckBoxClick() JavaScript functions as shown below. [script type="text/javascript" language="javascript"] function HeaderCheckBoxClick(checkbox) { var gridView = document.getElementById("GridView1"); for (i = 1; i [ gridView.rows.length; i++) { gridView.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = checkbox.checked; // Depending on whether the checkbox in the header is checked or // unchecked change the background color of the data rows in the GridView if (checkbox.checked) { gridView.rows[i].style.background = '#CCCCCC'; } else { gridView.rows[i].style.background = '#FFFFFF'; } } } function ChildCheckBoxClick(checkbox) { var atleastOneCheckBoxUnchecked = false; var gridView = document.getElementById("GridView1"); for (i = 1; i [ gridView.rows.length; i++) { // Depending on whether the checkbox in the data row is checked or // unchecked change the background color of the rows in the GridView if (gridView.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked == false) { gridView.rows[i].style.background = '#FFFFFF'; atleastOneCheckBoxUnchecked = true; } else { gridView.rows[i].style.background = '#CCCCCC'; } } gridView.rows[0].cells[0].getElementsByTagName("INPUT")[0].checked = !atleastOneCheckBoxUnchecked; } [/script] The following code makes the text in a GridView row bold on mouseover and normal on mouseout protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onmouseover", "this.style.fontWeight = 'bold';"); e.Row.Attributes.Add("onmouseout", "this.style.fontWeight= 'normal';"); } }
