Description
Occurs immediately after the position of the slider of this track bar changes.
Note: OnTracking is similar to OnChange with the key difference that OnTracking occurs after the slider is moved and before the control is released, while OnChange only occurs once the control is released (i.e., the value of the Position property changes).
