Hi All,
I downloaded the ajax tool kit and added to my tool box. But when I drag and drop ajax controls on my web form,The below errors I am getting.
 
1. Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The system cannot find the file specified.
2. Unknown server tag 'cc1:HoverMenuExtender.
 
Here is my .aspx code.
 
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<script runat="server">
    protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        Label1.ForeColor = System.Drawing.Color.FromName(RadioButtonList1.SelectedItem.Text);
    }

How come you're answering questions almost a year old. Your questionable actions have already roused our suspicion. Besides that you should really learn how to answer properly and inserting links that work too. For now I fixed that for you.
Try using ToolkitScriptManager instead of ScriptManager. If still it does not solve the issue then check with your Ajax version or reload Ajaxtoolkit again to your toolbox.
Its working fine on my side.
 
Specify exact error in case it is not resolved.
 
Happy Coding
