Occurs one or more times as the mouse pointer is moved when a Thumb control has logical focus and mouse capture.
Assembly: System.Windows (in System.Windows.dll)
The Thumb control receives logical focus and mouse capture when the user presses the left mouse button while the mouse pointer is paused over the Thumb. The Thumb control loses mouse capture when the user releases the left mouse button, or when the CancelDrag method is called.
A new event occurs each time the mouse pointer is moved. Therefore, this event can be raised repeatedly when a Thumb control has mouse capture.
