We have a got website in asp.net 4.0 , IIS 7, we get sys.extended.UI is null or not an object error.
I have made all possible changes in web.config and IIS 7 by changing from classic to integrated.
Can you please provide your valuable suggestions please, let me know if any details required.

"Sys.Extended.UI" is the namespace for AjaxControlToolkit 3.5 and 4.0. But the namespace for AjaxControlToolkit 3.0 or ealier is "AjaxControlToolkit".
So please download the latest version of AjaxControlToolkit and make the new reference into your project.
You should download the dll for .NET Framework 3.5 from this link:
I am absolutely sure that you are using the AjaxControlToolkit.dll with the version id of 3.0.30930.0. For this version, we need to use
AjaxControlToolkit instead of Sys.Extended.UI.
