Windows phone 7 + canvas + gesture + OnDrag events + pan / drag restriction

I have one container canvas inside which I load a large canvas. I use gesture listening methods. Several methods, such as OnDragStarted, OnDragDelta and OnDragCompleted, I use these methods to pan the inner (larger) canvas.

The problem is that I cannot limit the panning of the inner canvas, which means that I must be able to pan the inner canvas within the border of the outer canvas.

How can I do that?
