Remarks

You can think of a Storyboard as a container for other animation objects (for example, a DoubleAnimation) as well as other Storyboard objects. In other words, you can nest Storyboard objects within each other and specify BeginTime values for each Storyboard separately. Using nested storyboards can help you orchestrate elaborate animation sequences. Each child Storyboard waits until its parent Storyboard begins and then starts the countdown before it in turn begins.

You can use the interactive methods of the Storyboard object to start, pause, resume, and stop an animation. For more information, see Animation Overview.

NoteNote:

Do not attempt to call Storyboard members (for example, Begin) within the constructor of the page. This will cause the animation to fail silently.

Examples

The following example shows how to use the Begin, Stop, Pause, and Resume methods to control the playback of a storyboard (animation). A set of buttons allow the user to call these methods.
