Написал пример программной анимации для Windows Phone. Многим может пригодится.

private void animatelistboxItem(ListBoxItem item)
        {
            Storyboard sb = null;
            string animationstoryname=item.GetHashCode().ToString() +  "_listBoxItem_story";

            if (LayoutRoot.Resources[animationstoryname] != null)
            {
                sb = (LayoutRoot.Resources[animationstoryname] as Storyboard);
                sb.Stop();
                sb.Begin();
                return;
            }
            else

            }

            if (item.Projection == null)
