c# - ColorAnimation 为滑动时的 listviewItem 颜色设置动画 - WP8.1

Question

我正在尝试使用以下 Storyboard向右滑动更改 ListView 项目的颜色，但它引发了一个异常

WinRT information: ColorAnimation cannot be used to animate property Background due to incompatible type. Additional information: No installed components were detected.

这是我用过的代码。这个写在manipulationDelta事件中

Grid ChannelGrid = (Grid)sender;
Grid DeleteGrid = (Grid)((Grid)(ChannelGrid.Parent)).Children[1];

网格是 listviewitem 的项目模板，操作事件连接到它。

else if (e.Position.X - initialpoint.X > 30 && ChannelGrid.Width == 380) // Swipe right
        {
            e.Complete();
            Storyboard SwipeRight = new Storyboard();

            ColorAnimation changeColorAnimation = new ColorAnimation();
            changeColorAnimation.EnableDependentAnimation = true;
            changeColorAnimation.To = Colors.Green;
            changeColorAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(100));
            Storyboard.SetTarget(changeColorAnimation, ChannelGrid);
            Storyboard.SetTargetProperty(changeColorAnimation, "Background");//**WRONG**
            SwipeRight.Children.Add(changeColorAnimation);
            SwipeRight.Begin();
         }

找到解决方案 :D 导致异常的是 TargetProperty。您需要将目标属性设置如下

PropertyPath p = new PropertyPath("(ChannelGrid.Background).(SolidColorBrush.Color)");
Storyboard.SetTargetProperty(changeColorAnimation, p.Path);

不是

Storyboard.SetTargetProperty(changeColorAnimation, "Background");//**WRONG**
