A Clock object's ClockController property enables you to interactively start, pause, resume, seek, advance the clock to its fill period, and stop the clock. Only the root clock of a timing tree can be interactively controlled.

Note:
There are other ways to interactively control animations that don't require you to work directly with clocks: you can also use Storyboards. Storyboards are supported in both markup and code. For an example, see How to: Animate a Property by Using a Storyboard or the Animation Overview.

In the following example, several buttons are used to interactively control an animation clock.
