AjaxControlToolKit not found issue

Split off from http://forums.asp.net/t/1519956.aspx/1?AjaxControlToolKit+not+found+issue. Please don't necropost

hii,

I m using .NET Framework 4.0 and still I was unable to solve the problem. 

I had modified the web.config file as you shown above and I had added :

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

on every page where I had used Ajax.

Now I m not getting any errors, but the ajax contents are not shown on the page. other than ajax contents are shown on the page.

Please Help me in this regard.

Thanks in advance
