Thanks

thanks so much, it works. i shold make the project in framework 4.0 instead of 2.0

Are you asking if you should use 4.0 instead of 2.0? Well, the web server needs to support the framework. So, if it does and you want additional controls, then sure, I would.

No. I mean It was when I change the project to framework 4.0, then the ajax control now appear on the tool box.
