A trigger action that begins a Storyboard. Not commonly used. See Remarks.
A single Storyboard object element.
The BeginStoryboard class has these types of members:
The BeginStoryboard class has these constructors.
|BeginStoryboard||Initializes a new instance of the BeginStoryboard class.|
The BeginStoryboard class has these methods. It also inherits methods from the Object class.
|ClearValue||Clears the local value of a dependency property. (Inherited from DependencyObject)|
|GetAnimationBaseValue||Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)|
|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)|
The BeginStoryboard class has these properties.
|Read-only||Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)|
|Read/write||Gets or sets the Storyboard that this BeginStoryboard starts.|
|Read-only||Identifies the BeginStoryboard.Storyboard dependency property.|
Triggers, EventTrigger, Actions and BeginStoryboard are not commonly used. These APIs mainly exist for compatibility in XAML originally used for Microsoft Silverlight. For most scenarios where event triggers were used previously, you should either use 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 Quickstart: Control templates or Storyboarded animations.
If you do choose to use Triggers, in Windows Runtime XAML, the default behavior for event triggers and the only event that can be used to invoke an EventTrigger is FrameworkElement.Loaded. Because that's both the default and the only enabled behavior, you don't set RoutedEvent, and just use the XAML
<EventTrigger>. For more info, see Triggers.
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 (such as BeginStoryboard.Storyboard) omitted.
