Remarks
This DragCompleted event occurs when the left mouse button is released or when the CancelDrag method is called.
The Thumb control receives mouse capture when the user presses the left mouse button while pausing the mouse pointer over the Thumb control.
The position of the mouse when the DragCompleted event occurs is provided by the DragDeltaEventArgs of the last DragDelta event.
