我已经生成了一个XAML文件，其中包含一个带有学生姓名和图形的滚动查看器。当我点击其中一个名称时，相应的线将从左上角飞进来(从小到正确的大小)，并停止在轴上的右侧位置。
当我点击另一个名字时，它会触发同样的事情，但是当这些停在正确的位置时，前几行飞出屏幕并缩小到右下角。
直到我按下之前已经按过的名称为止。然后这些线开始很小，保持很小，并立即飞出右下角，而不是停止在适当大小的轴上。
我试过停止动画，但似乎不工作，任何帮助将非常感激。

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