Examples

This XAML example shows the basic structure for using FrameworkElement.Triggers with its default FrameworkElement.Loaded trigger behavior to run a storyboarded animation. This XAML shows the EventTrigger and BeginStoryboard container elements in proper relationship with each using their XAML content property syntax and unnecessary property element tags omitted.

<Canvas Width="200" Height="200" x:Name="animatedcanvas" Background="Red">
    <Canvas.Triggers>
        <EventTrigger>
            <BeginStoryboard>
                <Storyboard x:Name="ColorStoryboard">
                   <!-- Animate the background of the canvas to green over 4 seconds. -->
                    <ColorAnimation Storyboard.TargetName="animatedcanvas"
                      Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)"
                      To="Green" Duration="0:0:4" />
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Canvas.Triggers>
</Canvas>

Remarks

Triggers, EventTrigger, Actions and BeginStoryboard are not commonly used. These API mainly exist for compatibility in XAML originally used for Microsoft Silverlight. For most scenarios where event triggers were used previously, you should use built-in animations, visual states, or start animations by writing a Loaded handler that looks up an animation in page-level resources and then calls Begin on the animation's main Storyboard. For more info, see XAML Control templates or Storyboarded animations.
