Remarks

A VisualState specifies how the control looks when it is in a certain state. For example, when a Button is pressed, its border might be a different color than normal. The VisualState class has a Storyboard property that changes the appearance of the control. When the control enters the state that is specified by the VisualState.Name property, the Storyboard begins. When the control exits the state, the Storyboard stops.

The VisualStateGroup.States property contains VisualState objects. VisualStateGroup objects are added to the VisualStateManager.VisualStateGroups and are defined in the control's ControlTemplate. For information about how to create a ControlTemplate and VisualState objects for existing controls, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.

Control authors use the VisualStateManager to transition between states by passing the name of VisualState objects to the GoToState method.

Examples

The following example creates a VisualStateGroup in the ControlTemplate of a Button called CommonStates and adds VisualState objects for the states, Normal, Pressed, and MouseOver. The Button also defines a state called Disabled that is in the CommonStatesVisualStateGroup, but the example omits it for brevity. For the entire example, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.
