I created a user control in Visual Studio in .Net framework 3.5 and using Ajax Toolkit 3.5 and then added the Star Rating Ajax control to the user control.
Now I want to add this user control as a webpart to a sharepoint 2010 website. Since the user control already has a asp:ToolkitManager to do the work of script manager, adding this webpart to a page on the MOSS site gives a lot of errors. Currently, I have retained the asp:ToolkitManger in the user control.
The error I get whenever I open the MOSS page containing the user control is "PageRequestManager cannot be initialized more than once".
I have no idea how to go about it. Any suggestions are welcome.
EDIT: I believe the sharepoint master page has a script manager of its own. I can't remove it because the other pages will suffer. How do I modify the user control in Visual Studio so that it includes the ajax update panel but refers to the sharepoint script manager.
Perhaps the parent control or page already has ScriptManager defined...
