Event fired when an animation ends?

Hi all,

Is there any event that gets fired when an animation ends that we can
take advantage of? I have a simple animation that I'm creating in C#
code (I'm not doing it in XAML as it must be applied to any number of
elements in a collection at the click of a button, and I don't know how
one can do that in XAML).

It is meant to animate a property called ScaleFactor that I've declared
as a DP on a window, and it looks something like this (assume that w is
the window on which I want to animate the ScaleFactor DP):



DoubleAnimation scaleAnimationParams = new DoubleAnimation();

scaleAnimationParams.From = 1;
scaleAnimationParams.To = .25;
scaleAnimationParams.Duration = new Duration(new TimeSpan(0, 0, 0, 0,
500));
w.BeginAnimation(ManagedWindow.ScaleFactorProperty,scaleAnimationParams);


Now, is there a way to get notified when the animation is finished? The
only events that are available through the animation classes are:

- Changed
- CurrentGlobalSpeedInvalidated
- CurrentGlobalStateInvalidated
- CurrentTimeInvalidated

Thanks!
Jason

Taking this even further, it would be nice to have events fired when an
animation starts as well (given that you can specify a start time for an
animation which is not exactly now...)

Thanks,
Jason

scaleAnimationParams.CurrentStateInvalidated += delegate(object sender,
EventArgs e)
{
Clock clock = (Clock)sender;

if (clock.CurrentState == ClockState.Stopped)
{
// the animation has ended
....
}
};

if (clock.CurrentState == ClockState.Stopped)
should be
if (clock.CurrentState != ClockState.Active)
