Examples

The following example applies a FadeInThemeAnimation and FadeOutThemeAnimation to a rectangle.

<StackPanel>
    <StackPanel.Resources>

        <!-- Theme animations like this can use the default behavior like
             this example or you could use properties like BeginTime and 
             Duration to tweak when and how quickly the animation occures. 
             If you want more control over a fade animation (e.g. just partial
             fade), you will need to use DoubleAnimation to animate the Opacity 
             property of the element you want to fade in or out. -->
        <Storyboard x:Name="EnterStoryboard">
            <FadeOutThemeAnimation Storyboard.TargetName="myRectangle" />
        </Storyboard>
        <Storyboard x:Name="ExitStoryboard">
            <FadeInThemeAnimation Storyboard.TargetName="myRectangle" />
        </Storyboard>
    </StackPanel.Resources>
    <Rectangle x:Name="myRectangle" 
               PointerEntered="Rectangle_PointerEntered" 
               PointerExited="Rectangle_PointerExited"   
               Fill="Blue" Width="200" Height="300" />
</StackPanel>

// When the pointer enters the rectangle space, the animation begins.
private void Rectangle_PointerEntered(object sender, PointerRoutedEventArgs e)
{
    EnterStoryboard.Begin();
}

private void Rectangle_PointerExited(object sender, PointerRoutedEventArgs e)
{
    ExitStoryboard.Begin();
}

Constructors

FadeOutThemeAnimation()

Initializes a new instance of the FadeOutThemeAnimation class.

Properties

AutoReverse	Gets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration. (Inherited from Timeline)
BeginTime	Gets or sets the time at which this Timeline should begin. (Inherited from Timeline)
Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
Duration	Gets or sets the length of time for which this timeline plays, not counting repetitions. (Inherited from Timeline)
FillBehavior	Gets or sets a value that specifies how the animation behaves after it reaches the end of its active period. (Inherited from Timeline)
RepeatBehavior	Gets or sets the repeating behavior of this timeline. (Inherited from Timeline)
SpeedRatio	Gets or sets the rate, relative to its parent, at which time progresses for this Timeline. (Inherited from Timeline)
TargetName	Gets or sets the reference name of the control element being targeted.
TargetNameProperty	Identifies the TargetName dependency property.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

Events

Completed

Occurs when the Storyboard object has completed playing.
