HI all
When draging a button, I keep dragging the mouse to leave the the silverlight app frame.
Then loosen the leftbutton of mouse,
And move the mouse back the silverlight app frame.
The button is still stay at border of silverlight app frame.And the drag and drop event does not work again.
How to cancel the drag and drop when I drags a button outside the silverlight app frame?
