Animatable.ApplyAnimationClock Method

public:
 virtual void ApplyAnimationClock(System::Windows::DependencyProperty ^ dp, System::Windows::Media::Animation::AnimationClock ^ clock);

public void ApplyAnimationClock (System.Windows.DependencyProperty dp, System.Windows.Media.Animation.AnimationClock clock);

abstract member ApplyAnimationClock : System.Windows.DependencyProperty * System.Windows.Media.Animation.AnimationClock -> unit
override this.ApplyAnimationClock : System.Windows.DependencyProperty * System.Windows.Media.Animation.AnimationClock -> unit

Public Sub ApplyAnimationClock (dp As DependencyProperty, clock As AnimationClock)

Parameters

Implements

Remarks

Note that using this method to removing clocks from a property does not stop those clocks.

Parameters

Examples

The following example shows how to apply animation clocks using different HandoffBehavior settings.

Remarks

Note that using this method to remove clocks from a property does not stop those clocks.

Using the Compose HandoffBehavior

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 will 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.

• To remove all clocks from a property, use the ApplyAnimationClock(DependencyProperty, AnimationClock) or BeginAnimation(DependencyProperty, AnimationTimeline) method of the animated object. Specify the property being animated as the first parameter, and null as the second. This will remove all animation clocks from the property.

• To remove a specific AnimationClock from a list of clocks, use the Controller property of the AnimationClock to retrieve a ClockController, then call the Remove method of the ClockController. This is typically done in the Completed event handler for a clock. Note that only root clocks can be controlled by a ClockController; the Controller property of a child clock will return null. Note also that the Completed event will not be called if the effective duration of the clock is forever. In that case, the user will need to determine when to call Remove.

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