    Whether System.Web.Extensions.dll is available in the bin folder of the apploication or in the GAC?

    I guess that the DLL related to AJAX is missing in the BIN folder or in the GAC. If not, drop the file in the BIN folder and give a try.

    Hello Shashi,

    If ASP.NET Ajax not working then you should reinstall on your server the ASP.NET AJAX for Asp.Net 2.0. You can download it from the below link :

    If you don't have access in this server, you can upload the .dll file into the BIN folder.

    Hope this will help you.
