GroupBox 样式和模板

  • 项目

本主题介绍 GroupBox 控件的样式和模板。 可以修改默认 ControlTemplate 以赋予控件独特的外观。 有关详细信息，请参阅为控件创建模板。

GroupBox 部件

GroupBox 控件没有任何命名部件。

GroupBox 状态

下表列出了 GroupBox 控件的可视状态。

VisualState 名称 VisualStateGroup 名称 说明
有效 ValidationStates 该控件使用 Validation 类，Validation.HasError 附加属性为 false。
InvalidFocused ValidationStates 如果控件具有焦点，则 Validation.HasError 附加属性为 true。
InvalidUnfocused ValidationStates Validation.HasError 附加属性是让控件不具有焦点的 true。

GroupBox ControlTemplate 示例

以下示例演示如何定义 GroupBox 控件的 ControlTemplate。

<Style TargetType="GroupBox">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="GroupBox">
        <Grid>
          <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
          </Grid.RowDefinitions>
          <Border Grid.Row="0"
                  BorderThickness="1"
                  CornerRadius="2,2,0,0">
            <Border.BorderBrush>
              <LinearGradientBrush StartPoint="0,0"
                                   EndPoint="0,1">
                <LinearGradientBrush.GradientStops>
                  <GradientStopCollection>
                    <GradientStop Color="{DynamicResource BorderLightColor}"
                                  Offset="0.0" />
                    <GradientStop Color="{DynamicResource BorderDarkColor}"
                                  Offset="1.0" />
                  </GradientStopCollection>
                </LinearGradientBrush.GradientStops>
              </LinearGradientBrush>
            </Border.BorderBrush>

            <Border.Background>
              <LinearGradientBrush StartPoint="0,0"
                                   EndPoint="0,1">
                <LinearGradientBrush.GradientStops>
                  <GradientStopCollection>
                    <GradientStop Color="{DynamicResource ControlLightColor}"
                                  Offset="0.0" />
                    <GradientStop Color="{DynamicResource ControlMediumColor}"
                                  Offset="1.0" />
                  </GradientStopCollection>
                </LinearGradientBrush.GradientStops>
              </LinearGradientBrush>
            </Border.Background>

            <ContentPresenter Margin="4"
                              ContentSource="Header"
                              RecognizesAccessKey="True" />
          </Border>

          <Border Grid.Row="1"
                  BorderThickness="1,0,1,1"
                  CornerRadius="0,0,2,2">
            <Border.BorderBrush>
              <SolidColorBrush Color="{StaticResource BorderMediumColor}" />
            </Border.BorderBrush>
            <Border.Background>
              <LinearGradientBrush EndPoint="0.5,1"
                                   MappingMode="RelativeToBoundingBox"
                                   StartPoint="0.5,0">
                <GradientStop Color="{DynamicResource ContentAreaColorLight}"
                              Offset="0" />
                <GradientStop Color="{DynamicResource ContentAreaColorDark}"
                              Offset="1" />
              </LinearGradientBrush>
            </Border.Background>
            <ContentPresenter Margin="4" />
          </Border>
        </Grid>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

ControlTemplate 使用以下资源的一项或多项。
