好的，最近我没有做太多WPF，这使我感到困惑。
我有一个为Style定义的RadioButton，它使用带有ControlTemplate的MultiTrigger。要点是，当鼠标悬停在Border或IsChecked为true时，我希望MultiTrigger变得不透明。
因此，我有了Opacity，它可以在2种情况下对IsChecked进行动画处理。 IsMouseOver为false，IsChecked为true。然后，我还有另外3个触发器。一组是鼠标悬停在其上时要移动的光标。当IsChecked为false时，另一组将边界不透明度设置为0，而当RadioButton为true时，最后一组将不透明度设置为1。
我的问题是最终触发器无法按我期望的方式工作。被选中的MultiTrigger不再满足MultiTrigger的条件，因此动画不会发生，但是单击时边框的不透明度恢复为0。Style必须加上一些东西，因为注释掉它会使另一个触发器起作用。
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"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<Grid>
<Border
BorderThickness="1,0,1,0"
BorderBrush="{StaticResource XWhiteX}">
</Border>
<Border x:Name="outerBorder"
Background="{TemplateBinding Background}"
OpacityMask="{StaticResource TallVerticalMask}">
</Border>
<ContentControl
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center">
<TextBlock x:Name="txt" Style="{StaticResource ButtonText}" IsHitTestVisible="False"
Text="{TemplateBinding Content}"
VerticalAlignment="Center"
HorizontalAlignment="Center"/>
</ContentControl>
</Grid>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition SourceName="outerBorder" Property="UIElement.IsMouseOver" Value="True"/>
<Condition Property="RadioButton.IsChecked" Value="False"/>
</MultiTrigger.Conditions>
<MultiTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:0.2" Storyboard.TargetName="outerBorder" Storyboard.TargetProperty="(UIElement.Opacity)" To="1"/>
</Storyboard>
</BeginStoryboard>
</MultiTrigger.EnterActions>
<MultiTrigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:0.5" Storyboard.TargetName="outerBorder" Storyboard.TargetProperty="(UIElement.Opacity)" To="0"/>
</Storyboard>
</BeginStoryboard>
</MultiTrigger.ExitActions>
</MultiTrigger>
<Trigger Property="UIElement.IsMouseOver" Value="True">
<Setter Property="Cursor" Value="Hand"/>
</Trigger>
<Trigger Property="RadioButton.IsChecked" Value="False">
<Setter TargetName="outerBorder" Property="Opacity" Value="0"/>
</Trigger>
<Trigger Property="RadioButton.IsChecked" Value="True">
<Setter TargetName="outerBorder" Property="Opacity" Value="1"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我真的不确定为什么单击边框时边框会逐渐消失。
一如既往，任何帮助将不胜感激。

最佳答案
这是一个解决方案，
我修改了externalBorder以指定Opacity = 0：
<Border x:Name="outerBorder" Background="{TemplateBinding Background}" OpacityMask="{StaticResource TallVerticalMask}" Opacity="0">
</Border>
命名为ExitAction的故事板：
<MultiTrigger.ExitActions>
<BeginStoryboard Name="ExitStoryBoard">
...
并用以下代码替换RadioButton.IsChecked的触发器：
<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>
