A single Storyboard, object element.
The BeginStoryboard type exposes the following members.
|BeginStoryboard||Initializes a new instance of the BeginStoryboard class.|
|Dispatcher||Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)|
|Storyboard||Gets or sets the Storyboard that this BeginStoryboard starts.|
|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 Silverlight 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.)|
Triggers have only limited support in Silverlight. For more information, see Triggers.
In addition to starting a storyboard automatically when an object loads, you can use the interactive methods of the Storyboard object to start, pause, resume, and stop an animation. For more information, see Animation Overview.
The following example shows how to use a Storyboard and a BeginStoryboard to make a rectangle that fades in and out of view after it is loaded.
<Canvas> <Rectangle x:Name="MyAnimatedRectangle" Width="100" Height="100" Fill="Blue"> <Rectangle.Triggers> <!-- Animates the rectangle's opacity. --> <EventTrigger RoutedEvent="Rectangle.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="MyAnimatedRectangle" Storyboard.TargetProperty="Opacity" From="1.0" To="0.0" Duration="0:0:5" AutoReverse="True" RepeatBehavior="Forever" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Rectangle.Triggers> </Rectangle> </Canvas>
Supported in: 5, 4, 3
