Storyboard.Begin Method (FrameworkContentElement, HandoffBehavior)

Applies the animations associated with this Storyboard to their targets and initiates them, using the specified HandoffBehavior.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationFramework (in PresentationFramework.dll)

member Begin : 
        containingObject:FrameworkContentElement * 
        handoffBehavior:HandoffBehavior -> unit

Parameters

containingObject
Type: System.Windows.FrameworkContentElement

An object contained within the same name scope as the targets of this storyboard's animations. Animations without a TargetName are applied to containingObject.

handoffBehavior
Type: System.Windows.Media.Animation.HandoffBehavior

The behavior the new animation should use to interact with any current animations.

When you apply a Storyboard, AnimationTimeline, or AnimationClock to a property using the Compose HandoffBehavior, any Clock objects previously associated with that property continue to consume system resources; the timing system does not remove these clocks automatically.

To avoid performance issues when you apply a large number of clocks using Compose, you should remove composing clocks from the animated property after they complete. There are several ways to remove a clock.

This is primarily an issue for animations on objects that have a long lifetime. When an object is garbage collected, its clocks are also disconnected and garbage collected.

For more information about clock objects, see Animation and Timing System Overview.

The following example uses the SnapshotAndReplace HandoffBehavior to animate when the user left-clicks, and the Compose HandoffBehavior when the user right-clicks.
