[QUOTE="morpheus_xx, post: 1155373, member: 48495"] I have checked this. One error is in markup, it needs to be x:Key="[B]Alternative_[/B]Footer_Template". But the real issue is, that you cannot address another element by name from within a control template. I have tried to set DataContext to TemplatedParent, didn't help. I tried different ways for binding without success. The issue is the name lookup in control: it tries to find the control, then it looks in parent until a INameScope is found. This happens inside template only, not the screen which uses the template. This means we would need a backing model for menu item selection where we can bind to from footer. So no immediate solution possible right now :( [/QUOTE]
