Hi Riaz,

The RadSideDrawer is of type View, therefore you can indeed use it in a ContentPage. 

One thing to be aware when you're creating such a scenario is to be aware of the user's gestures and to understand what control will work with which gestures. I would try setting the DrawerLocation to the top or bottom so that it doesn't conflict with the MasterDetail horizontal swipe gesture.

Note: Nesting two components that do the same thing is not recommended, so to get this to work you may need to tweak it (e.g. disable the MasterDetail's gesture recognition by setting IsGestureEnabled).
