How to get notifications when a thumb drag is started and completed?

The DragStarted event is raised when a thumb is dragged. After the thumb releases the pointer capture, the DragCompleted event is raised. The Index property of the DragThumbEventArgs returns a int value, which indicates the thumb used for performing drag operations.
