Remarks

ScrollViewerViewChangingEventArgs includes the IsInertial property, which reports whether the manipulation that is firing the event contains an inertial component.

Not every underlying manipulation will necessarily fire this event. The ScrollViewer logic delays and consolidates intermediate events into a single occurrence in some cases.
