It would be better to catch the MouseLeftButtonDown at the Canvas level and then check to see what (if any) control is at that location. But, top of my head, I'm not sure how Silverlight handles this (I've only done it in WPF)

Crude (if you drag too fast the mouse up can occur outside the Rectangle etc) but should get you started.....
