The Thumb control receives logical focus and cursor capture when the user taps the Thumb. The Thumb control loses cursor capture when the lifts their finger from the screen, or when the CancelDrag method is called.
A new event occurs each time the user drags their finger across the screen. Therefore, this event can be raised repeatedly when a Thumb control has cursor capture.
