Could you please, explain in more details the type of properties tab you wish to implement. A screenshot would be very helpful.
If you wish to use a theme across your entire application, I suggest that you would better set an application theme in App.xaml.cs
rather than the MainPage. For example:
This way you do not need to define RadDocking in the MainPage, but you could define it in Views/Home.xaml.
I hope this helps.
