Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.

Actually 2 versions of ajax are referred:version 2.0 and 4.1

I have given in web config runtime tag:

assemblyidentity name="Sys.Extended.UI" publickeytoken="28f01b0e84b6d53e" culture="neutral" 
bindingredirect oldversion="" newversion="4.1.40412.0" 

Still then also,in one form with collapsiblepanelextender ,its showing the above mentioned error and Sys.Extended.UI is null.

how to solve this?
