Question

I have a storyboard that seems to stop randomly by itself, I cannot for the life of me figure out why.

It seems to stop and random intervals.

private void CreateStoryboard(int from)
    {
        int? targetTo;
        Duration dur;
        targetTo = 150;
        dur = 150;

        Int32Animation element = new Int32Animation();
        element.From = from;
        element.To = targetTo;
        element.Duration = dur;
        Storyboard.SetTargetProperty(element, new PropertyPath(CurrentFrameProperty));
        _filmstripStoryboard = new Storyboard {SpeedRatio = this.FrameRate};
        _filmstripStoryboard.Children.Add(element);
        _filmstripStoryboard.Completed += new EventHandler(FilmstripStoryboard_Completed);
         _filmstripStoryboard.Begin(this, true);
    }

As you can see im affecting the custom “CurrentFrameProperty” DP, which has a callback method that I print out the current frame.

For some reason, and I have just no idea why, the storyboard just stops. The completed event does NOT get fired, and the callback method stops getting called.

And I am sure that I am not calling stop() anywhere.

If anyone has had this issue or can help me debug it, I would be very grateful.

It was the deconstructors! My objects with a reference to the storyboards and animations were getting destroyed, so the animation just looked like it froze up.
