Use this class with an EventTrigger or a Trigger to resume a paused Storyboard. A ResumeStoryboard object can only resume a Storyboard that is paused and has no effect on a Storyboard in any other state.

To be able to pause, resume, or otherwise control a Storyboard interactively, set the Name property of its BeginStoryboard and use a ControllableStoryboardAction object (such as PauseStoryboard, ResumeStoryboard, or StopStoryboard) to control it by referencing its Name. If the Name of BeginStoryboard is unspecified, the Storyboard cannot be interactively controlled after it starts. For more information, see How to: Use Event Triggers to Control a Storyboard After It Starts.

This example shows how to control a Storyboard after it starts. To start a Storyboard by using XAML, use BeginStoryboard, which distributes the animations to the objects and properties they animate, and starts the storyboard. If you give BeginStoryboard a name by specifying its Name property, you make it a controllable storyboard. You can then interactively control the storyboard after it starts.

Use the following storyboard actions together with EventTrigger objects to control a storyboard.

  • PauseStoryboard: Pauses the storyboard.

  • ResumeStoryboard: Resumes a paused storyboard.

  • SetStoryboardSpeedRatio: Changes the storyboard speed.

  • SkipStoryboardToFill: Advances a storyboard to the end of its fill period, if it has one.

  • StopStoryboard: Stops the storyboard.

  • RemoveStoryboard: Removes the storyboard, freeing resources.

The following example uses controllable storyboard actions to interactively control a storyboard.

Note: To see an example of controlling a storyboard by using code, see How to: Control a Storyboard After It Starts.
