代码隐藏中的 WinRT/Metro 动画 [英] WinRT/Metro Animation in code-behind

问题描述

以下代码在 Silverlight 中运行良好:

The following code works fine in Silverlight:

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，它需要一个小改动才能编译:

In WinRT/Metro it needs one minor change to make it compile:

Storyboard.SetTargetProperty(doubleAnimation, "Width");

但是当你运行它时，什么也没有发生.

but when you run it, nothing happens.

如果您将属性从宽度"更改为不透明度"(同时更改 From=0 和 To=1)，则有效.

If you change the property from "Width" to "Opacity" (also change From=0 and To=1) that works.

宽度"有什么问题?

推荐答案

需要添加以下内容:

doubleAnimation.EnableDependentAnimation = true;

这似乎解决了问题.
