I just downloaded the Q1 2010 release. I'm trying to implement a header context menu similar to what is shown in the samples. However, I get an error:
"Undefined CLR namespace. The 'clr-namespace' URI refers to a namespace 'Telerik.Windows.Controls.GridView.HeaderMenu' that is not included in the assembly"
Obviously, something's changed. Is there another way to get a context menu on the GridView header?
