Creating and Applying Themes Dynamically in ASP.NET

Creating and Applying Themes Dynamically

In this article, I will show you step by step procedure, how to Create and Apply Themes Dynamically in ASP.NET using Visual Studio 2005 or Visual Studio 2008.

To follow this code sample, you must use Visual Studio 2005 or Visual Studio 2008.

I have used <! –    –> to comment HTML part of the code.

Note: Creating and Applying Themes Dynamically is a part of AjaxControlToolkit.
To attach right click on the toolbox under Ajax Extensions and select Choose Items - > Browse Button - > select the AjaxControlToolkit.dll. If you are using Visual Studio 2008, you may not need AJAX Toolkit but if you are using Visual Studio 2005, you will need to download it from http://www.msdn.com/ or http://www.asp.net/.

Step 1. Start -> All Programs -> Visual Studio 2005 or Visual Studio 2008

Step 2. Now go to File Menu -> New -> Web Site

Step 3. 

Under Visual Studio Installed Template-> Choose ASP.NET WEB SITE -> Choose File System from the location combo box -> Set the path by the browse button - > Choose the language from the Language ComboBox (Visual C# , Visual Basic , J #)

Choose Visual C#

Step 4. Click on the OK Button.

This is the source code window and in this page you will se this code. 

 

<%@ Page Language=”C#” AutoEventWireup=”true”  CodeFile=”Default.aspx.cs” Inherits=”_Default” %>

 

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

 

<html xmlns=”http://www.w3.org/1999/xhtml”>

<head runat=”server”>

<title>Type your webpage title here</title>  <!– Here you can specify your page title in between title tag ->

</head>

<body>

<form id=”form1? runat=”server”>

<div>

 

<!– In between div tags you can manage your web controls like buttons, labels, picture Box, ImageMap etc –>

 

 

</div>

</form>

</body>

</html>
