Transitions a control between states.

Namespace:   System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

protected virtual bool GoToStateCore(
	FrameworkElement control,
	FrameworkElement stateGroupsRoot,
	string stateName,
	VisualStateGroup group,
	VisualState state,
	bool useTransitions


Type: System.Windows.FrameworkElement

The control to transition between states.

Type: System.Windows.FrameworkElement

The root element that contains the VisualStateManager.

Type: System.String

The name of the state to transition to.

Type: System.Windows.VisualStateGroup

The VisualStateGroup that the state belongs to.

Type: System.Windows.VisualState

The representation of the state to transition to.

Type: System.Boolean

true to use a VisualTransition object to transition between states; otherwise, false.

Return Value

Type: System.Boolean

true if the control successfully transitioned to the new state; otherwise, false.

The GoToStateCore method performs the logic necessary to appropriately start and stop the storyboards that are associated with a transition. When a control calls GoToState to change its state, the VisualStateManager does the following:

  • First, if the VisualState that the control is transitioning to has a Storyboard, the storyboard begins. Then, if the VisualState that the control is coming from has a Storyboard, the storyboard ends.

  • If the control is already in the stateName state, GoToState takes no action and returns true.

  • If stateName does not exist in the ControlTemplate of control, GoToState takes no action and returns false.

You can implement your own VisualStateManager to provide different logic for transitioning between states. For example, you can change the logic described previously, or you can provide logic to transition between custom animation types. To implement a VisualStateManager, create a class that inherits from VisualStateManager and override the GoToStateCore method. To use the custom class, set the CustomVisualStateManager property to an object of your custom type.
