ZoomPanel Events

PreviewViewboxChanged occurs before the Viewbox or RotationAngle is changed. The event can be used to prevent the change of viewbox or RotationAngle (set Handled property to true), or change the new viewbox or RotationAngle before the change is applied.

ViewboxAnimationCompleted occurs after the animation that changed the Viewbox is completed (if Viewbox change was not animated, this event is not fired).

ViewboxAnimationStarted occurs after when the animation that change the Viewbox is started (if Viewbox change is not animated, this event is not fired).

ViewboxChanged occurs after the Viewbox value is changed. If the zooming is animated the event fires when the animation begins - the NewValue is not the current Viewbox value but the final value when the animation will be completed.

ZoomModeChanged occurs when ZoomMode is changed
