I'm having problems getting the ItemTemplateSelector and ContentTemplateSelector to work with RadRibbonView. The template selectors work great w/ TabControl, and I would like to implement mvvm by associating each tab within the tabcontrol with a respective ribbon. Your mvvm demo at http://demos.telerik.com/silverlight/#RibbonView/MVVM
uses templateselectors only w/ buttons, but not groups or ribbons. Is it possible to do this? When I modify your demo code for the Ribbon to use a dummy selector, it remains unused.
