简单的一个，我想要一个没有标题空间的 GroupBox

最接近的是边框，但边框“默认”不具有与组框相同的样式。

获得所需 GroupBox 的最简单方法（最少 xaml / 代码）是什么？

谢谢

如果您真的不想要边框，那么可以有以下两种解决方案：

(1) 在 blend 中编辑模板：

  • 右键单击 GroupBox > 编辑模板 > 编辑副本 > 确定

  • 搜索部分

      <Border.OpacityMask>
       <MultiBinding Converter="{StaticResource BorderGapMaskConverter}" ConverterParameter="7">
            ......
       </MultiBinding>
  </Border.OpacityMask>

  • 删除这个（上面提到的）部分。你刚刚删除了“差距”

  • 现在，如果您不设置标题（如示例中所示），这将起作用。但是，如果您设置标题，它将在边框后面。所以要纠正这个问题，只需Panel.ZIndex="-1"在包含您刚刚删除的部分的边框中设置（看起来像<Border BorderBrush="White" BorderThickness= ...）

(2) 使用复制的 GroupBox 并将其水平翻转并将其放置在原始 groupbox 下方：

  • 将此代码放在您的 groupbox 下方（假设您的 groupbox 的名称是 ' OriginalGroupbox'）

     <GroupBox Header="" Focusable="False" Panel.ZIndex="-1" 
           Width="{Binding ActualWidth, ElementName=OriginalGroupbox}" 
           Height="{Binding ActualHeight, ElementName=OriginalGroupbox}" 
           IsEnabled="{Binding IsEnabled, ElementName=OriginalGroupbox}"
           RenderTransformOrigin="0.5,0.5">
           <GroupBox.RenderTransform>
                <ScaleTransform ScaleX="-1"/>
           </GroupBox.RenderTransform>
 </GroupBox>

  • 将这两个 GroupBox 包含在这样的格式中Grid：

    <Grid>
     <GroupBox x:Name="OriginalGroupbox" Header="Mihir" ...>
        ...
     </GroupBox>
     <GroupBox Header="" Width="{Binding ActualWidth, ElementName=OriginalGroupbox}" ...>
        ...
     </GroupBox>
</Grid>

您可以通过将边框更改为圆角和不同颜色来模拟组框的样式。这是一个看起来非常接近 GroupBox 边框的边框：

<Border BorderThickness="1" CornerRadius="4" Height="100" Width="100" Padding="5" BorderBrush="LightGray"><TextBlock>Border</TextBlock></Border>

基于 Mihir Gokani 的回答，您可以更改默认模板以使用触发器在标题为空或为空时将标题的填充更改为空。

在 GroupBox 上使用以下样式，应该可以修复它。

<BorderGapMaskConverter x:Key="BorderGapMaskConverter"/>
<Style x:Key="GroupBoxStyle" TargetType="{x:Type GroupBox}">
    <Setter Property="BorderBrush" Value="#D5DFE5"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type GroupBox}">
                <Grid SnapsToDevicePixels="true">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="6"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="6"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                        <RowDefinition Height="6"/>
                    </Grid.RowDefinitions>
                    <Border BorderBrush="Transparent" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.ColumnSpan="4" Grid.Column="0" CornerRadius="4" Grid.Row="1" Grid.RowSpan="3"/>
                    <Border x:Name="Header" Grid.Column="1" Padding="3,1,3,0" Grid.Row="0" Grid.RowSpan="2">
                        <ContentPresenter ContentSource="Header" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                    </Border>
                    <ContentPresenter Grid.ColumnSpan="2" Grid.Column="1" Margin="{TemplateBinding Padding}" Grid.Row="2" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                    <Border BorderBrush="White" BorderThickness="{TemplateBinding BorderThickness}" Grid.ColumnSpan="4" CornerRadius="4" Grid.Row="1" Grid.RowSpan="3">
                        <Border.OpacityMask>
                            <MultiBinding ConverterParameter="7" Converter="{StaticResource BorderGapMaskConverter}">
                                <Binding ElementName="Header" Path="ActualWidth"/>
                                <Binding Path="ActualWidth" RelativeSource="{RelativeSource Self}"/>
                                <Binding Path="ActualHeight" RelativeSource="{RelativeSource Self}"/>
                            </MultiBinding>
                        </Border.OpacityMask>
                        <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3">
                            <Border BorderBrush="White" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="2"/>
                        </Border>
                    </Border>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="Header" Value="{x:Null}">
                        <Setter TargetName="Header" Property="Padding" Value="0" />                                 
                    </Trigger>
                        <Trigger Property="Header" Value="">
                            <Setter TargetName="Header" Property="Padding" Value="0" />
                        </Trigger>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

注意唯一的补充是：

<ControlTemplate.Triggers>
    <Trigger Property="Header" Value="{x:Null}">
        <Setter TargetName="Header" Property="Padding" Value="0" />                                 
    </Trigger>
    <Trigger Property="Header" Value="">
        <Setter TargetName="Header" Property="Padding" Value="0" />
    </Trigger>
</ControlTemplate.Triggers>

我一直在寻找类似的解决方案。我需要一种仅在没有标题文本时才关闭边框的组框样式。

我不相信这是最好的解决方案，但它工作正常......

我们有一个转换器（仅适用于文本 atm）：

public class GroupBoxHeaderVisibilityConverter : IMultiValueConverter
{
    #region IMultiValueConverter Members

    public object Convert(object[] values, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        ContentPresenter header = values[0] as ContentPresenter;
        if (header != null)
        {
            string text = header.Content as string;
            if (string.IsNullOrEmpty(text))
            {
                return 0.0;
            }
        }
        return values[1];
    }

    public object[] ConvertBack(object value, System.Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new System.NotImplementedException();
    }

    #endregion
}

以及对组框样式的修改：

<Border
    x:Name="Header"
    Grid.Column="1"
    Grid.Row="0"
    Grid.RowSpan="2"
    Padding="3,1,3,0">
    <Border.Tag>
        <MultiBinding Converter="{StaticResource GroupBoxHeaderVisibilityConverter}">
            <Binding Path="Content" ElementName="groupBoxLabel" />
            <Binding Path="ActualWidth" RelativeSource="{RelativeSource Self}" />
        </MultiBinding> 
    </Border.Tag>
    <Label x:Name="groupBoxLabel"
        FontSize="{StaticResource Fonts_SmallFontSize}"
        Foreground="{TemplateBinding Foreground}">
        <ContentPresenter
            SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
            ContentSource="Header"
            RecognizesAccessKey="True" />
    </Label>
</Border>
<ContentPresenter
    Margin="{TemplateBinding Padding}"
    SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
    Grid.Column="1"
    Grid.ColumnSpan="2"
    Grid.Row="2" />
<Border
    Grid.ColumnSpan="4"
    Grid.Row="1"
    Grid.RowSpan="3"
    BorderBrush="Transparent"
    BorderThickness="{TemplateBinding BorderThickness}"
    CornerRadius="4">
    <Border.OpacityMask>                                
        <MultiBinding
            Converter="{StaticResource BorderGapMaskConverter}"
            ConverterParameter="7">
            <Binding ElementName="Header" Path="Tag" />
            <Binding
                Path="ActualWidth"
                RelativeSource="{RelativeSource Self}" />
            <Binding
                Path="ActualHeight"
                RelativeSource="{RelativeSource Self}" />
        </MultiBinding>
    </Border.OpacityMask>
    <Border
        BorderBrush="{TemplateBinding BorderBrush}"
        BorderThickness="{TemplateBinding BorderThickness}"
        CornerRadius="3" />
</Border>
