VisualTransition Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents the visual behavior that occurs when the control transitions from one state to another.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
The VisualTransition type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| From | Gets or sets the name of the VisualState to transition from. |
| GeneratedDuration | Gets or sets the amount of time it takes to move from one state to another. |
| GeneratedEasingFunction | Gets or sets the easing function applied to the generated animations. |
| Storyboard | Gets or sets the Storyboard that occurs when the transition occurs. |
| To | Gets or sets the name of the VisualState to transition to. |
| Name | Description | |
|---|---|---|
 | 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 Windows Phone 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.) |
You can specify the visual behavior of a control when it transitions between states by adding VisualTransition objects to the ControlTemplate. When you create a VisualTransition, you specify one or more of the following:
The time it takes for a transition between states to occur by setting the GeneratedDuration property.
Additional changes in the control's appearance that occur at the time of the transition by setting the Storyboard property.
When the VisualTransition is applied by setting the To and From properties.
The following example creates a VisualTransition that specifies that when the user moves the pointer away from the control, the control's border changes to blue, then to yellow, then to black in 1.5 seconds.
<!--Take one and a half seconds to transition from the MouseOver state to the Normal state. Have the SolidColorBrush, BorderBrush, fade to blue, then to yellow, and then to black in that time.--> <VisualTransition From="MouseOver" To="Normal" GeneratedDuration="0:0:1.5"> <Storyboard> <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="Color" Storyboard.TargetName="BorderBrush" FillBehavior="HoldEnd" > <ColorAnimationUsingKeyFrames.KeyFrames> <LinearColorKeyFrame Value="{StaticResource PhoneSubtleColor}" KeyTime="0:0:0.5" /> <LinearColorKeyFrame Value="{StaticResource PhoneContrastBackgroundColor}" KeyTime="0:0:1" /> <LinearColorKeyFrame Value="{StaticResource PhoneForegroundColor}" KeyTime="0:0:1.5" /> </ColorAnimationUsingKeyFrames.KeyFrames> </ColorAnimationUsingKeyFrames> </Storyboard> </VisualTransition>
