[surface] 코드로 만든 Fade out Control

Xaml이 아닌 코드로 만들어서 범용적이고 실용적으로 사용 가능

public static class FadeAnimationControl
{
    public static void Fade(UIElement target, double ValueFrom, double ValueTo, double Duration)
    {
        DoubleAnimation da = new DoubleAnimation();
        da.From = ValueFrom;
        da.To = ValueTo;
        da.Duration = TimeSpan.FromSeconds(Duration);
        da.AutoReverse = false;

        System.Windows.Media.Animation.Storyboard.SetTargetProperty(da, new PropertyPath("Opacity"));

        System.Windows.Media.Animation.Storyboard.SetTarget(da, target);

        System.Windows.Media.Animation.Storyboard sb = new System.Windows.Media.Animation.Storyboard();
        sb.Children.Add(da);

        EventHandler eh = null;
        eh = (s, args) =>
        {
            //target.Visibility = Visibility.Collapsed;
            sb.Stop();
            sb.Completed -= eh;
            target.Opacity = ValueTo;
        };
        sb.Completed += eh;

        sb.Begin();
    }
}
