In web.config
<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,

That's the original Microsoft AJAX Framework 1.0 You can download here:

Are you running Visual Studio 2008 with AJAX 3.5? If so, you could *try*
reversioning the assembly. Change the 1.0.61025.0 to and give it
a shot. Most everything works between the versions, so it'd be worth a shot.

You can double check what versions of assembly files you have loaded in the
GAC by going to Start > Run > assembly (no quotes, no exe, etc), then browsing
down to System.Web.Extensions.




Thank U Sir,
It works ::))

Now I have one more issue.
I have downloaded Ajax frame work and in the toolbox I am getting AJAX
Extention in which i find the Script manager.
Bit,in the design form I am not getting this part of the tag..
I also added AjaxControlToolkit.dll in the bin directory.
