Hi All,

       I have developed a module which uses the telerik controls. It is running fine on the site built on .net 3.5 framework. I use the Telerik.Web.UI.dll 2.0 version for making it to work with sites built on .net 2.0. But i get a very strange error while installing the module on the sites built on .net2.0 framework. The same package works fine sites built on .net 3.5 framework. I get the script manager error as.

A critical error has occurred.
The control with ID 'RadTabStrip1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

Stack Trace

Method: Telerik.Web.UI.ScriptRegistrar.GetScriptManager
StackTrace:
Message: DotNetNuke.Services.Exceptions.PageLoadException: The control with ID 'RadTabStrip1' requires a ScriptManager on the page.

Hi,

  I am using 4.8.4.

Hi,

   Ok a little debugging i have found that the condition

   If DotNetNuke.Framework.AJAX.IsInstalled Then
                   DotNetNuke.Framework.AJAX.RegisterScriptManager()

End if

is failing and the script manager is not being registered and throwing an error for the sites built on 2.0 and for the sites built on  3.5 it is going inside the loop and registering the scriptmanager and module works fine. both sites are built on 4.4.4 only. why is it so. Why Ajax installed condition is failing

please help

Thanks,

Sandeep
