How to know when Composition animation 'ScalarKeyFrameAnimation' (or similar) finished

Question

I need to know when Composition animation like ScalarKeyFrameAnimation finished. How to do this? I've made a call like following:

    public void Start()
    {
        if (!IsLoaded) return;
        //SET TARGET PROPERTY - OPACITY
        TargetScalarKeyFrameAnimation.Target = "Opacity";

        //SET FROM OPACITY
        if (From < 0) this.Opacity = 0;
        else if (From > 1) this.Opacity = 1;
        else this.Opacity = From;

        //SET FINAL VALUE (OPACITY) 
        if (To < 0) TargetScalarKeyFrameAnimation.InsertKeyFrame(1f, 0);
        else if (To > 1) TargetScalarKeyFrameAnimation.InsertKeyFrame(1f, 1);
        else TargetScalarKeyFrameAnimation.InsertKeyFrame(1f, (float)To);

        //SET DURATION
        if (Duration.TotalMilliseconds > 0) TargetScalarKeyFrameAnimation.Duration = Duration;
        else TargetScalarKeyFrameAnimation.Duration = TimeSpan.FromSeconds(1);

        //SET DELAY
        if (Delay.TotalMilliseconds > 0) TargetScalarKeyFrameAnimation.DelayTime = Delay;
        else TargetScalarKeyFrameAnimation.DelayTime = TimeSpan.FromMilliseconds(0);

        //START
        this.StartAnimation(TargetScalarKeyFrameAnimation);
    }

But how to get notification animation has been finished? It will helps lot to synchronise UI and other animation. StoryboardAnimation has an event for this.

How to know when Composition animation 'ScalarKeyFrameAnimation' (or similar) finished

Currently, there is no such event that could detect animation finished for composition Api. For your scenario, you could make a timer ans set Interval same as animation duration, and call StartAnimation and timer Start at same time. Then could detect animation finished in timer Tick event.
