VisualState Class


Represents the visual appearance of the control when it is in a specific state.

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

public class VisualState : DependencyObject


Initializes a new instance of the VisualState class.


Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.)


Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)


Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.)


Gets or sets the name of the VisualState.


Gets or sets a Storyboard that defines the appearance of the control when it is in the state that is represented by the VisualState.


Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)


Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)


Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)


Coerces the value of the specified . This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.)GTMT


Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Gets a hash code for this DependencyObject.(Inherited from DependencyObject.)


Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)


Gets the Type of the current instance.(Inherited from Object.)


Returns the current effective value of a on this instance of a DependencyObject. (Inherited from DependencyObject.)GTMT


Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Invoked whenever the effective value of any on this DependencyObject has been updated. The specific dependency property that changed is reported in the event data. (Inherited from DependencyObject.)GTMT


Returns the local value of a , if it exists. (Inherited from DependencyObject.)GTMT

System_CAPS_pubmethodSetCurrentValue(DependencyProperty, Object)

Sets the value of a without changing its value source. (Inherited from DependencyObject.)GTMT

System_CAPS_pubmethodSetValue(DependencyProperty, Object)

Sets the local value of a , specified by its dependency property identifier. (Inherited from DependencyObject.)GTMT

System_CAPS_pubmethodSetValue(DependencyPropertyKey, Object)

Sets the local value of a read-only , specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)GTMT


Returns a value that indicates whether serialization processes should serialize the value for the provided .(Inherited from DependencyObject.)GTMT


Returns a string that represents the current object.(Inherited from Object.)


Enforces that the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

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 attached property, which is defined on the on a FrameworkElement. You can add VisualState objects to any FrameworkElement, but they are typically are used in a ControlTemplate of a Control. For information about how to create a ControlTemplate and VisualState objects for existing controls, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate. For an example of using VisualState objects outside of a ControlTemplate, see the VisualStateManager class.

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 Creating a ControlTemplate.
