Wpf 属性触发器中按钮的前景未更改

为什么触发会起作用（鼠标结束时将按钮的前景更改为“红色”）

但当按钮的前景被设置为颜色（在本例中为“蓝色”）时，该触发器不是吗

按钮的本地值覆盖样式。尝试：

<Grid>

    <Grid.Resources>
        <Style TargetType="{x:Type Button}">
            <Setter Property="Foreground" Value="Blue"/>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Foreground" Value="Red"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>

    <Button Content="Hello"/>

</Grid>

我知道这是一篇老文章，但这是解决方案（在属性触发器中）。答复:

<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="Blue"/>

最合乎逻辑的方法是：

<Setter Property="Foreground" Value="Blue"/>

但是。。不工作..

只需添加一个控件模板，然后以您的样式将

ContentPresenter

的

TextElement.前台

绑定到

{TemplateBinding前台}

：

<Grid>
    <Grid.Resources>
        <Style TargetType="{x:Type Button}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                            <ContentPresenter TextElement.Foreground="{TemplateBinding Foreground}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Foreground" Value="Red"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>
    <Button Content="Hello"/>
</Grid>

我不确定，但我认为最好删除除英语以外的特定语言的句子。

<Setter Property="Foreground" Value="Blue"/>

<Grid>
    <Grid.Resources>
        <Style TargetType="{x:Type Button}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                            <ContentPresenter TextElement.Foreground="{TemplateBinding Foreground}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Foreground" Value="Red"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>
    <Button Content="Hello"/>
</Grid>
