Question

我有一个带有四列和四行的网格控件的窗口。它包含以下内容：

<Label Name="HeightLabel" Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" Content="Height" Target="{Binding ElementName=HeightValue}"/>
<TextBox Name="HeightValue" Grid.Column="0" Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Top" TextAlignment="Center"/>

<Label Name="WeightLabel" Grid.Column="2" Grid.Row="0" Grid.ColumnSpan="2" Content="Weight" Target="{Binding ElementName=WeightValue}"/>
<TextBox Name="WeightValue" Grid.Column="2" Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Top" TextAlignment="Center"/>

<Label Name="WidthLabel" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" Content="Width" Target="{Binding ElementName=WidthValue}"/>
<TextBox Name="WidthValue" Grid.Column="0" Grid.Row="3" HorizontalAlignment="Stretch" VerticalAlignment="Top" TextAlignment="Center"/>

<Label Name="LengthLabel" Grid.Column="2" Grid.Row="2" Grid.ColumnSpan="2" Content="Length" Target="{Binding ElementName=LengthValue}"/>
<TextBox Name="LengthValue" Grid.Column="2" Grid.Row="3" HorizontalAlignment="Stretch" VerticalAlignment="Top" TextAlignment="Center"/>

在资源字典中应用以下样式：

<Style TargetType="{x:Type Label}">
    <Setter Property="OverridesDefaultStyle" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Label}">
                <Border>
                    <ContentPresenter TextBlock.FontSize="18"
                                      TextBlock.Foreground="Red" 
                                      HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}" 
                                      RecognizesAccessKey="True"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

问题是只有最后一个标签控件被设置样式;其余的都接收默认的TextBlock样式。我知道Label包含一个嵌入式TextBlock，这使得样式比大多数其他控件更难，所以我怀疑存在某种层次结构问题，但对于我的生活，我无法弄明白。

使用VALID Style时，它们都会在我的屏幕上显示样式。你有几个问题，比如Foreground =“{Red}”而不是Foreground =“Red”，而且缺少一个/＆gt;

<Style TargetType="{x:Type Label}">
    <Setter Property="OverridesDefaultStyle" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Label}">
                <Border>
                    <ContentPresenter TextBlock.FontSize="18"
                                      TextBlock.Foreground="Red" 
                                      HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}" 
                                      RecognizesAccessKey="True" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

根据我上面的评论，问题是当未指定访问密钥加速器时，Label将呈现为TextBlock，因此我的Label样式未被应用。

样式未应用于容器中的所有控件
