I am using the Q2 2011 version of Telerik's ASP.NET AJAX controls installed with Visual Studio 2010.
I have dropped a RadScheduler onto my Test.aspx and I am binding it to a SQL Server backend, much like the RadScheduler TimelineView example that is included/installed with the Telerik controls. Everything was good, until I applied a GroupBy to the scheduler control. With the GroupBy included, my data no longer appears in the scheduler control when I browse the Test.aspx.
The GroupBy was initially assigned to the overall scheduler control, and no data would appear in any of the 4 scheduler views (Day, Week, Month, or Timeline). Then I moved the GroupBy to just the <TimelineView> and I could then see data in every view (Day, Week, and Month), except the Timeline view. If I completely remove the GroupBy from the scheduler, I can once again see data in all 4 views, but I want to be able to group my data.
I can't locate the cause of the problem. Here is my Test.aspx (there is no code directly behind this aspx):
