我无法将MouseOver样式应用于ContentPresenter内的Path.

我有一个包含ContentPresenter的Button样式:

<Style x:Key="ContentButton" TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <ContentPresenter
                x:Name="contentPresenter"
                Content="{TemplateBinding Content}">
                    <ContentPresenter.Resources>
                    <Style TargetType="{x:Type Path}"
                        BasedOn="{StaticResource ContentButtonPathStyle}"/>
                    </ContentPresenter.Resources>
                </ContentPresenter>

这是一种风格,所以我可以在路径上有一个翻转效果:

<Style x:Key="ContentButtonPathStyle" TargetType="{x:Type Path}">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Fill" Value="#FF00FF10"/>
            <Setter Property="Stroke" Value="Red"/>
            <Setter Property="StrokeThickness" Value="6"/>
        </Trigger>
    </Style.Triggers>
    <Setter Property="Stroke" Value="Red"/>
    <Setter Property="Fill">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="#FFB4B3E7" Offset="0"/>
                <GradientStop Color="#FF0800FF" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
</Style>

我还有一个图标资源文件,其中包含一个包含路径的Viewbox:

<Viewbox x:Key="MyIcon">
    <Grid>
        <Path Data="M78,296 L37.5,306.5 45.5,354.5 123.5,343.5 z" />
    </Grid>
</Viewbox>

最后,我创建了一个按钮并将Viewbox资源分配给内容:

<Button Style="{DynamicResource ContentButton}"> …

我有一个带有ContentPresenter模板的按钮样式,我试图将路径的填充绑定到按钮的前景:

<!-- This is inside the template of a button style -->
<ContentPresenter>
 <ContentPresenter.Resources>
  <Style TargetType="{x:Type Path}">
   <Setter Property="Fill" Value="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType=Button}}"/>
   </Style>
  </ContentPresenter.Resources>
</ContentPresenter>

我也有一个没有填充集的路径,我可以在按钮中引用内容,如下所示:

<Button Style="{DynamicResource MyButtonStyle}" Content="{DynamicResource PathIcon}" Foreground="Blue"/>

我希望按钮内的路径是蓝色的,但它不是......它不会从按钮中获取前景.

如何获取绑定到按钮颜色的路径？

谢谢!

PS:

如果我在值中加入硬编码颜色(即值="红色"),按钮内的路径为红色...所以我知道它有效......

<ContentPresenter>
 <ContentPresenter.Resources>
  <Style TargetType="{x:Type Path}">
   <Setter Property="Fill" Value="Red"/>
   </Style>
  </ContentPresenter.Resources>
</ContentPresenter>

这是完整的Style和ControlTemplate:

<Style x:Key="Button_Style" TargetType="{x:Type Button}">
        <Setter Property="Foreground" Value="{StaticResource White_Brush}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid x:Name="grid" Background="Transparent">
                        <ContentPresenter>
                            <ContentPresenter.Resources>
                                <Style TargetType="{x:Type Path}">
                                    <Setter Property="Fill" Value="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType=Button}}"/>
                                </Style> …
