silverlight：淡出按钮？

Question

一旦点击按钮，我会使按钮不可见。是否有任何漂亮的动画（可编程的代码背后的代码）使按钮消失而不是突然消失？

Answer 1

这应该对你有帮助。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(); 
    }
