I am using a custom User Control that requires the RadScriptManager control in order to function since it is using numerous RadControls for ASP.NET AJAX.
I have included the RadScriptManager in the Title & Properties for my Sitefinity Content Page, but this functionality does not seem sufficient to get my controls to render properly.
When I subsequently add the RadScriptManager directly to my User Control, I get an error message in the Error Log file as well as within my Sitefinity Content Page "Only one instance of a ScriptManager can be added to the page".
How do I resolve this error message in my Sitefinity Content Page as well as within my error log files and still get the content leveraging the RadControls for ASP.NET AJAX to render properly?
Please advise since this issue has been plaguing me since Sitefinity v. 4.x.
