I thing there are two ways to do what you're looking for:
- you can use our RadTabControl, add some mouse handlers (you can do this in XAML or change their default template and do it there if you're using business objects) and some custom logic.
- you can use a couple of buttons and the RadTransitionControl. In this case you could directly change the content of the Transition control on Click/Checked and etc.
I've attached a sample project which shows both approaches so could you please examine it and if you have more questions feel free to ask.
All the best,
