Hi, I have a problem, I worte a webpart to work in Sharepoint, this webpart have a RadSlider, well My webpart work fine with the RadScriptManager, but I tried to put a PerformancePoint webpart in the same page of my telerik webpart but this had a problem:
Unable to cast object of type 'Telerik.Web.UI.RadScriptManager' to type 'Microsoft.PerformancePoint.Scorecards.WebParts.ScriptManagerLoader'.
I found a thread for the solution ( http://blogs.msdn.com/fooshen/archive/2008/10/18/performance-point-server-2007-and-ajax-on-sharepoint.aspx ), but when I change the RadScriptManager for the PPS:ScriptManagerLoader my slider is disabled, and when I try to edit my page (Edit Page in SharePoint) I have this error:
Server Error in '/' Application.
