这是我的代码：

  <Style  TargetType="ContentControl" x:Key="MenuItemsStyle">
                <Setter Property="Background" Value="Transparent"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                          <Border Name="mainBorder" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
                                        <Border.Style>
                                            <Style TargetType="Border">
                                                <Setter Property="BorderThickness" Value="1.2"/>
                                                <Setter Property="Background" >
                                                    <Setter.Value>
                                                        <SolidColorBrush Color="Transparent"/>
                                                    </Setter.Value>
                                                </Setter>
                                                <Setter Property="BorderBrush" >
                                                    <Setter.Value>
                                                        <SolidColorBrush Color="Transparent"/>
                                                    </Setter.Value>
                                                </Setter>
                                                <Style.Triggers>
                                                    <EventTrigger RoutedEvent="Border.MouseEnter">
                                                        <BeginStoryboard Storyboard="{StaticResource BorderEnterStoryBoard}"/>

如您所见，我在窗口资源中创建了 4 个故事板，然后将它们用于样式和模板。

1.我怎样才能运行一次故事板？用户单击内容控件后，内容控件现在填充窗口空间，如果用户再次单击内容控件，我希望动画（情节提要）不再运行。（我想停止所有情节提要均采用边框样式，模板和内容控件样式） 2.我怎样才能更好地做到这一点（我的意思是使用 1 或 2 个故事板并调用它们一次，例如在鼠标按下内容时调用所有内容）

编辑： 故事板在这里：
