protected void RaiseCurrentStateChanged (System.Windows.VisualStateGroup stateGroup, System.Windows.VisualState oldState, System.Windows.VisualState newState, System.Windows.FrameworkElement control, System.Windows.FrameworkElement stateGroupsRoot);

member this.RaiseCurrentStateChanged : System.Windows.VisualStateGroup * System.Windows.VisualState * System.Windows.VisualState * System.Windows.FrameworkElement * System.Windows.FrameworkElement -> unit

Protected Sub RaiseCurrentStateChanged (stateGroup As VisualStateGroup, oldState As VisualState, newState As VisualState, control As FrameworkElement, stateGroupsRoot As FrameworkElement)

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 is transitioning to.

control: FrameworkElement

The control that is transitioning states.

stateGroupsRoot: FrameworkElement

The root element that contains the VisualStateManager.

Exceptions

ArgumentNullException

stateGroupsRoot is null.

-or-

newState is null.

Remarks

When the VisualStateGroup is set on the ControlTemplate of a control, the control parameter is set to the control that owns ControlTemplate. When the VisualStateGroup is set on a FrameworkElement, control is null and you should use the stateGroupsRoot parameter.

Notes to Inheritors

When overriding RaiseCurrentStateChanged(VisualStateGroup, VisualState, VisualState, FrameworkElement, FrameworkElement) in a derived class, be sure to call the base class' RaiseCurrentStateChanged(VisualStateGroup, VisualState, VisualState, FrameworkElement, FrameworkElement) method so that registered delegates receive the event.
