Is there animation end event (Completed) in DirectComposition and VisualLayer?

Hi,

I want to do animations using Visual Layer and DirectComposition...and, I have problem to find animation end event...event when animation actually ends / is completed.
Like (C#):

animation.AnimationEnd += handler;

Or, like in WPF timeline.Completed += handler;

I have multiple consequently chained animations...each animation starts after last ends. The moment animation actually ends?

Timer is not solution, because I need exact moment when some animation ends...to proceed with next animation.

Thanks in forward!
