Question

我创建了一个表，当MouseMove出现时，我想更改TableRow的背景颜色，并且当MouseLeave发生时，它将返回到TableRow的旧颜色。这是编码，但它不起作用。

currentRow.MouseMove += new MouseEventHandler(ShowRowColor);
currentRow.MouseLeave += new MouseEventHandler(HideRowColor);

void ShowRowColor(object sender, System.Windows.Input.MouseEventArgs e){
        TableRow tr = sender as TableRow;
        ColorAnimation animation = new ColorAnimation();
        animation.From = (tr.Background as SolidColorBrush).Color;
        animation.To = Colors.Indigo;
        animation.Duration = new Duration(TimeSpan.FromSeconds(5));
        tr.BeginAnimation(SolidColorBrush.ColorProperty,animation);
    }

    void HideRowColor(object sender, System.Windows.Input.MouseEventArgs e) {
        TableRow tr = sender as TableRow;
        ColorAnimation animation;
        animation = new ColorAnimation();
        animation.From = Colors.Indigo;
        animation.To = (tr.Background as SolidColorBrush).Color;
        animation.Duration = new Duration(TimeSpan.FromSeconds(1));
        tr.BeginAnimation(SolidColorBrush.ColorProperty,animation);
    }

请帮助我......

您需要在Background的{{1}}属性上启动动画，因为您需要定位TableRow的{{1}}属性

示例：

Color
