Definition
Important

When overridden in a derived class, fires the CurrentStateChanging event on the specified VisualStateGroup.
protected:
virtual void RaiseCurrentStateChanging(VisualStateGroup ^ stateGroup, VisualState ^ oldState, VisualState ^ newState, Control ^ control) = RaiseCurrentStateChanging;
void RaiseCurrentStateChanging(VisualStateGroup const& stateGroup, VisualState const& oldState, VisualState const& newState, Control const& control);
protected void RaiseCurrentStateChanging(VisualStateGroup stateGroup, VisualState oldState, VisualState newState, Control control);
function raiseCurrentStateChanging(stateGroup, oldState, newState, control)
Protected Sub RaiseCurrentStateChanging (stateGroup As VisualStateGroup, oldState As VisualState, newState As VisualState, control As Control)
Parameters
- stateGroup
- VisualStateGroup
The object that the CurrentStateChanging event occurred on.
- oldState
- VisualState
The state that the control is transitioning from.
- newState
- VisualState
The state that the control should transition to.
- control
- Control
The control where the transition animation between states is applied.
Remarks
This API is part of the scenario of defining a custom VisualStateManager behavior. The most important method to override in this scenario is GoToStateCore, because it's that method that changes the state behavior in your custom class behavior. Overriding the behavior of RaiseCurrentStateChanged and RaiseCurrentStateChanging
is optional: how and when the events are raised by the default implementation might be adequate for your custom class.
