Assembly: PresentationFramework (in PresentationFramework.dll)
A controllable storyboard can pause, resume, seek, stop, and be removed. To make a storyboard controllable in code, you must use the appropriate overload of the storyboard's Begin method and specify true to make it controllable. For an example, see How to: Control a Storyboard After It Starts.
All interactive actions taken on a Clock, and therefore also on a Storyboard, occur on the next tick of the timing engine, which happens shortly before the next render. This means that the Remove method still affects the animated properties until this time. In other words, the next time the frame is displayed, the storyboard is removed. If you need to disassociate an animation from a property before this time, use the BeginAnimation method with an animation parameter value of null.
