代码隐藏中的WinRT / Metro动画

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?

您需要添加以下内容:

 doubleAnimation.EnableDependentAnimation = true; 

这似乎解决了这个问题。

我不确定但尝试使用:

 Storyboard.SetTargetProperty(doubleAnimation, Button.WidthProperty); 

代替

 Storyboard.SetTargetProperty(doubleAnimation, "Width");
