C# 故事板动画不重置位置
C# Storyboard animation doesn't reset position
我生成了一个 XAML 文件，其中包含一个带有学生姓名和图表的滚动查看器。当我单击其中一个名称时，相应的线将从左上角飞入（也从小到正确的尺寸）并停在轴上的正确位置。
当我点击另一个名字时，它会触发同样的事情，但是当它们停在正确的位置时，前面的线条飞出屏幕并从右下角向下缩小。
这一切都有效，直到我按下一个我之前已经按下过的名字。然后这些线开始变小，保持变小，然后立即飞出右下角，而不是以适当的大小停在轴上。
我试过停止动画，但似乎不起作用，如有任何帮助，我们将不胜感激。

1 - 使用完成的事件来停止或删除故事板，如下所示：
<Storyboard Completed="storyboard_Completed" x:Name="Marilyn_Williamson_Line_1_StoryboardLine">
在后面的代码中：
private void storyboard_Completed(object sender, EventArgs e)
{
string StoryBoardName = ((ClockGroup)sender).Timeline.Name;
if (StoryBoardName == "storyboard1") { storyboard1.Stop(); storyboard1.Remove(); }
}
2 - 在每个 storyboard.Begin();
之前放置 storyboard.Stop();

1 - 使用完成的事件来停止或删除故事板，如下所示：
<Storyboard Completed="storyboard_Completed" x:Name="Marilyn_Williamson_Line_1_StoryboardLine">
在后面的代码中：
private void storyboard_Completed(object sender, EventArgs e)
{
string StoryBoardName = ((ClockGroup)sender).Timeline.Name;
if (StoryBoardName == "storyboard1") { storyboard1.Stop(); storyboard1.Remove(); }
}
2 - 在每个 storyboard.Begin();
storyboard.Stop();
