GoToStateCore Method

VisualStateManager.GoToStateCore Method (FrameworkElement, FrameworkElement, String, VisualStateGroup, VisualState, Boolean)

.NET Framework (current version)
 

Transitions a control between states.

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

abstract GoToStateCore : 
        control:FrameworkElement *
        stateGroupsRoot:FrameworkElement *
        stateName:string *
        group:VisualStateGroup *
        state:VisualState *
        useTransitions:bool -> bool
override GoToStateCore : 
        control:FrameworkElement *
        stateGroupsRoot:FrameworkElement *
        stateName:string *
        group:VisualStateGroup *
        state:VisualState *
        useTransitions:bool -> bool

Parameters

control
Type: System.Windows.FrameworkElement

The control to transition between states.

stateGroupsRoot
Type: System.Windows.FrameworkElement

The root element that contains the VisualStateManager.

stateName
Type: System.String

The name of the state to transition to.

group
Type: System.Windows.VisualStateGroup

The VisualStateGroup that the state belongs to.

state
Type: System.Windows.VisualState

The representation of the state to transition to.

useTransitions
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.
