# How to: Interactively Control a Clock
|
|
A <xref:System.Windows.Media.Animation.Clock> object's <xref:System.Windows.Media.Animation.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 [Animate a Property by Using a Storyboard](how-to-animate-a-property-by-using-a-storyboard.md) or the [Animation Overview](animation-overview.md).
|
|
|
|
In the following example, several buttons are used to interactively control an animation clock.
