代码隐藏中的WinRT/Metro动画

Question

以下代码在Silverlight中正常工作:

private void Button_Click_1(object sender, RoutedEventArgs e)
{    
    Storyboard storyboard = new Storyboard();
    DoubleAnimation doubleAnimation = new DoubleAnimation();
    doubleAnimation.From = 50;
    doubleAnimation.To = 100;
    doubleAnimation.RepeatBehavior = RepeatBehavior.Forever;
    doubleAnimation.AutoReverse = true;
    doubleAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(200));
    storyboard.Children.Add(doubleAnimation);
    Storyboard.SetTarget(doubleAnimation, button1);
    Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Width"));
    storyboard.Begin();
}

在WinRT/Metro中,它需要一个小的改动才能编译:

Storyboard.SetTargetProperty(doubleAnimation, "Width");

但是当你运行它时,没有任何反应.

如果您将属性从"宽度"更改为"不透明度"(也可以更改从= 0和To = 1).

"宽度"有什么问题？

Answer 1

您需要添加以下内容:

doubleAnimation.EnableDependentAnimation = true;

这似乎解决了这个问题.
