How to Create ContactUs page using Rich TextBox in Asp.Net

Introduction:

As we know, ASP.NET lacks a control that we need most, RichText editor.

If you are trying to create an application or website with Admin Panel or Blog or Forum Website or some such project for Web in ASP.NET platform, we need RichText Editor.
To overcome this, we can use many open source JavaScript based editors, like Tiny MCE, FCKEditor, etc.

here we are using TinyMCE, which is one of the most popular and Open Source projects. Download the latest version of TinyMCE from download page, and extract the zip file.

Steps:

Create a new WebPage  in VS 2008.

Browse the extracted location and go to ..\tinymce_3.5.6\tinymce\jscripts folder.
Now copy the tinymce folder from the above location to your solution in Visual Studio.

Step 1:

Create a WebPage file named ContactUs.aspx.

Paste the code below into ContactUs.aspx:



<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Contact Us Form</title>
    <script type="text/javascript" src="tinymce/jscripts/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">
   tinyMCE.init({
