故事板动画没有动画
Storyboard animation does not animate
我创建了一个自定义控件，它的目的是显示任务的当前状态，在没有动画的情况下更改选择的部分已经完成，我正在努力的是动画。它不播放应该是的整个序列：状态 1：最小化 => 将前景更改为灰色 | => 状态 2：将前景更改为白色 => 突出显示。相反，它似乎跳过了故事板。

为了让另一个故事板动画化，我们需要停止上一个动画故事板，为此，我们必须为所有 <BeginStoryboard> 设置一个名称，之后我们开始一个新的故事板（<BeginStoryboard>) 我们应该调用其他 <StopStoryboard BeginStoryboardName="Storyboard1"/> 在 <BeginStoryboard x:Name="Storyboard2">
