Hello,
Just in case anyone wants a workaround, I found a way to add buttons to the TitleTemplate that are bound to your viewmodel. This is how you do it:
What you do is you have your Header in your RadPane bind to your ViewModel, and then you create a TitleTemplate that has buttons, and bind to the commands/properties in your view model. When I click on the button in my TitleTemplate, I am able to access the command in my ViewModel.
Just wanted to post this just in case anyone comes across this thread.
