silverlight：淡出按钮？

Question

单击按钮后，我会使按钮不可见。是否有任何漂亮的动画（可编程代码来自代码）代码可以消除按钮而不是突然消失？

这应该对你有所帮助。只需致电FadeOut(myButton)：

    private void FadeOut(UIElement fe, int seconds = 2)
    {
        DoubleAnimation animation = new DoubleAnimation() { To = 0, Duration = new Duration(new TimeSpan(0, 0, seconds)) };
        Storyboard sb = new Storyboard();
        sb.Children.Add(animation);
        Storyboard.SetTarget(animation, fe);
        Storyboard.SetTargetProperty(animation, new PropertyPath(UIElement.OpacityProperty));
        sb.Begin();
    }
