can any body tell me what is wrong?

Did you copy the needed files (.dll) of the ajax control toolkit in the /bin subfolder?

If this is an ASP.NET 2.0 application you also have to install the Ajax 1.0 extensions first in order to get it to work. Also you have to make sure that you use the correct ajax control toolkit which maps to the exact .NET framework version under which your application's running. You can't just plug in the latest toolkit version as you wish.
