[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Occurs when a control begins transitioning into a different state.
Assembly: System.Windows (in System.Windows.dll)
The event occurs when the control begins to transition states. If a VisualTransition is applied to the state change, this event occurs when the transition begins. If a VisualTransition is not applied, this event occurs after the control goes to the new state before the CurrentStateChanged event.
