Examples

The following example shows how to use the Begin, Stop, Pause, and Resume methods to control the playback of a storyboard (animation). A set of buttons allow the user to call these methods.

<StackPanel x:Name="LayoutRoot" >
    <StackPanel.Resources>
        <Storyboard x:Name="myStoryboard">
            <DoubleAnimation From="1" To="6" Duration="00:00:6" 
            Storyboard.TargetName="rectScaleTransform" 
            Storyboard.TargetProperty="ScaleY">
                <DoubleAnimation.EasingFunction>
                    <BounceEase Bounces="2" EasingMode="EaseOut" 
                            Bounciness="2" />
                </DoubleAnimation.EasingFunction>
            </DoubleAnimation>
        </Storyboard>
    </StackPanel.Resources>

    <!-- Button that begins animation. -->
    <Button Click="Animation_Begin"
         Margin="2" Content="Begin" />

    <!-- Button that pauses Animation. -->
    <Button Click="Animation_Pause"
         Margin="2" Content="Pause" />

    <!-- Button that resumes Animation. -->
    <Button Click="Animation_Resume"
         Margin="2" Content="Resume" />

    <!-- Button that stops Animation. Stopping the animation 
         returns the ellipse to its original location. -->
    <Button Click="Animation_Stop"
         Margin="2" Content="Stop" />

    <Rectangle Fill="Blue" Width="200" Height="30">
        <Rectangle.RenderTransform>
            <ScaleTransform x:Name="rectScaleTransform" />
        </Rectangle.RenderTransform>
    </Rectangle>

Remarks

Storyboard is an important class in the concept of storyboarded animations. For more info on the concept, see Storyboarded animations.

Storyboard is used for these properties:

• VisualState.Storyboard
• VisualTransition.Storyboard
• BeginStoryboard.Storyboard

These properties aren't the only place where a Storyboard is defined. The typical way that a Storyboard is used for a storyboarded animation is that the Storyboard is defined in a Resources collection (either Application.Resources or FrameworkElement.Resources, or possibly as a resource within a file such as Generic.xaml for a custom control). Whenever it's defined as a XAML resource, you should always assign an x:Name attribute value to your Storyboard. You can then reference the name as a programming variable later in code-behind. You'll need this reference to actually run the animations that the Storyboard contains, by calling the Begin method on that Storyboard instance. Storyboard also has other control methods such as Stop that can control the animation thereafter.

Storyboard inherits several properties from Timeline. These properties can be applied either to a Storyboard or to one of the animations within it (in the Children collection). There are pros and cons to setting Timeline properties on the main Storyboard instead of on each animation. For more info, see Storyboarded animations.

You also need a Storyboard in order to control the predefined animations that you add to controls or UI, if you are using one of the theme animations. Theme animations don't have an innate trigger point, so you need to contain theme animations in a Storyboard as the Children. If the Storyboard is used as the VisualState.Storyboard value then the animation runs when that visual state is loaded. Or, if it's in a VisualTransition.Storyboard, the animation runs when that transition is detected by the visual state manager. These are the most common way to use a theme animation, but you could also put one in a loose Storyboard resource and explicitly start the animation by calling Begin.

XAML attached properties

Storyboard is the host service class for several XAML attached properties. These enable child animations under control by the Storyboard to each target separate target elements and target properties, while still following the same controlling timeline and triggering mechanism as the parent.

In order to support XAML processor access to the attached properties, and also to expose equivalent get and set operations to code, each XAML attached property has a pair of Get and Set accessor methods. Another way to get or set the value in code is to use the dependency property system, calling either GetValue or SetValue and passing the identifier field as the dependency property identifier.
