Thetype exposes the following members.
|CurrentState||Gets the most recently set VisualState from a successful call to the GoToState method.|
|Dispatcher||Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)|
|Name||Gets the name of the .|
|States||Gets the collection of mutually exclusive VisualState objects.|
|Transitions||Gets the collection of VisualTransition objects.|
|CheckAccess||Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)|
|ClearValue||Clears the local value of a dependency property. (Inherited from DependencyObject.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetAnimationBaseValue||Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ReadLocalValue||Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)|
|SetValue||Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
ControlTemplate authors VisualState objects to a in a ControlTemplate to specify the visual behavior of the control. You put states that are mutually exclusive to each other in the same . For example, the CheckBox has two objects. One contains the states, Normal, MouseOver, Pressed, and Disabled. The other contains the states, Checked, UnChecked, and Indeterminate. The CheckBox can be in states MouseOver and UnChecked at the same time, but it cannot be in the MouseOver and Pressed states at the same time.
Control authors specify which states the control can be in by putting the TemplateVisualStateAttribute, on its class definition. States with the same TemplateVisualStateAttribute.GroupName belong in the same .
For more information about using objects in a ControlTemplate, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.
The following example creates a simple ControlTemplate for a Button that contains one Grid. It also contains a called CommonStates, which defines the MouseOver and Normal states. The also has a VisualTransition that specifies that it takes one half second for the Grid to change from green to red when the user puts the mouse over the Button.
<ControlTemplate TargetType="Button"> <Grid > <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualStateGroup.Transitions> <!--Take one half second to trasition to the MouseOver state.--> <VisualTransition To="MouseOver" GeneratedDuration="0:0:0.5"/> </VisualStateGroup.Transitions> <VisualState x:Name="Normal" /> <!--Change the SolidColorBrush, ButtonBrush, to red when the mouse is over the button.--> <VisualState x:Name="MouseOver"> <Storyboard> <ColorAnimation Storyboard.TargetName="ButtonBrush" Storyboard.TargetProperty="Color" To="Red" /> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid.Background> <SolidColorBrush x:Name="ButtonBrush" Color="Green"/> </Grid.Background> </Grid> </ControlTemplate>
