Remarks
In addition to the default processing of the DragStarted event, this implementation displays a tooltip that shows the Value of the Slider when the AutoToolTipPlacement property is not set to None.
This implementation does not handle the DragStarted event. The value of the Handled property of the DragCompletedEventArgs is not changed.
This method can be overridden to customize the way a Slider processes Thumb movements.
