WPF-ControlTemplate中的多触发器，奇怪的行为

好吧，我最近没有做太多WPF，这让我很困惑

我为

单选按钮定义了
样式
，它使用
控制模板
和
多触发器
。要点是，当鼠标悬停在
边框上或当它被选中时，
边框
将变得不透明

因此我有了
multi-trigger
，它可以在两种条件下设置
不透明度
输入和输出的动画
IsChecked
为假，
IsMouseOver
为真。我还有另外3个触发器。一组是鼠标在其上时要使用的光标。当
IsChecked
为假时，另一组的边框不透明度设置为0，当
IsChecked
为真时，最后一组设置不透明度为1

我的问题是，最后的触发器没有按我预期的方式工作。选中的
单选按钮
不再满足
多触发器
的条件，因此动画不会发生，但单击时边框的不透明度返回到0

必须对
多触发器进行一些操作，因为注释它会使另一个触发器工作

样式的代码如下-

    <Style TargetType="RadioButton" x:Key="MenuFlameButton">
    <Setter Property="Width" Value="80"/>
    <Setter Property="FontFamily" Value="/#SlabTallX"/>
    <Setter Property="FontSize" Value="16"/>

我真的不知道为什么当我点击它时边界会消失

    <RadioButton
        Margin="2,0,2,0"
        Background="{StaticResource ColorFlameSectionGreen}"
        Content="Settings"
        DockPanel.Dock="Right"
        Style="{StaticResource MenuFlameButton}"
        Tag="Settings"/>
    <RadioButton
        Margin="2,0,2,0"
        Background="{StaticResource ColorFlameSectionBlue}"
        Content="Event Log"
        DockPanel.Dock="Right"
        Style="{StaticResource MenuFlameButton}"
        Tag="EventLog"/>
    <RadioButton
        Margin="2,0,2,0"
        Background="{StaticResource ColorFlameSectionPurple}"
        Content="Queue"
        DockPanel.Dock="Right"
        Style="{StaticResource MenuFlameButton}"
        Tag="Queue"/>
    <RadioButton
        Margin="2,0,2,0"
        Background="{StaticResource ColorFlameSectionRed}"
        Content="Debug"
        DockPanel.Dock="Right"
        Style="{StaticResource MenuFlameButton}"
        Tag="Debug"/>
</DockPanel>




这里有一个解决方案，
我修改了OuterOrder以指定不透明度=0：

<Border x:Name="outerBorder" Background="{TemplateBinding Background}" OpacityMask="{StaticResource TallVerticalMask}" Opacity="0">
                            </Border>



将ExitAction的故事板命名为：

<MultiTrigger.ExitActions>
    <BeginStoryboard Name="ExitStoryBoard">
    ...


...

并替换了RadioButton的触发器。检查如下：

    <Trigger Property="RadioButton.IsChecked" Value="True">
            <Trigger.EnterActions>
                    <PauseStoryboard BeginStoryboardName="ExitStoryBoard"/>
            </Trigger.EnterActions>
            <Trigger.Setters>
                    <Setter TargetName="outerBorder" Property="Opacity" Value="1"/>
            </Trigger.Setters>
            <Trigger.ExitActions>
                    <ResumeStoryboard BeginStoryboardName="ExitStoryBoard"/>
            </Trigger.ExitActions>
    </Trigger>
