Storyboard.SeekAlignedToLastTick Method (TimeSpan, TimeSeekOrigin)
Seeks this Storyboard to a new position immediately (synchronously).
Assembly: PresentationFramework (in PresentationFramework.dll)
SeekAlignedToLastTick aligns the seeked time of the Storyboard with the last clock tick. Values are immediately updated to reflect the changes due to SeekAlignedToLastTick, even though the screen does not reflect these changes until the screen updates.
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.
