I'm brand new to Telerik controls, so I know I'm not doing something right.  I have a RadDock whose ContentTemplate contains a UserControl containing a RadListBox.  The controls contained in the ItemTemplate do not appear.  I believe I"ve narrowed down the issue to the attached code.  Can you tell me why the RadListBox content does not appear?  In the code sample I have the exact same code outside of the RadDock and it displays fine.   Also, I have the exact same problem when adding my UserControl to a RadSlidingPane. The contained listbox again does no appear.
Thanks for your help,
Chris
