WPF中复选框左侧的文字？

Question

将复选框内容（文本）放在复选框本身左侧的最简单方法是什么？

Answer 1

最大化“宽松度”和“正确性”的解决方案是使用RightToLeft内容制作LeftToRight复选框：

<CheckBox FlowDirection="RightToLeft">
    <TextBlock FlowDirection="LeftToRight" Text="CheckBox Content:" />
</CheckBox>

或者如果你喜欢一种风格：

<Style TargetType="CheckBox">
    <Setter Property="FlowDirection" Value="RightToLeft" />
    <Setter Property="ContentTemplate">
        <Setter.Value>
            <DataTemplate>
                <ContentControl FlowDirection="LeftToRight" Content="{Binding}" />
            </DataTemplate>
        </Setter.Value>
    </Setter>
</Style>

Answer 2

在代码中：

System.Windows.Controls.CheckBox checkBox = new System.Windows.Controls.CheckBox();
checkBox.Content = ":CheckBox Enabled";
checkBox.FlowDirection = System.Windows.FlowDirection.RightToLeft;

在XAML中：

<CheckBox FlowDirection="RightToLeft" Content=":CheckBox Enabled" />

编辑

用户punker76帮助我注意到冒号“：”必须位于正确显示的文本前面（“CheckBox Enabled：”），可能是由于文本元素上的影响流方向引起的。很好的抓住。

另一种方法是制作新的自定义样式

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <SolidColorBrush Color="#F4F4F4"
                   x:Key="CheckBoxFillNormal" />
  <SolidColorBrush Color="#8E8F8F"
                   x:Key="CheckBoxStroke" />
  <Style x:Key="EmptyCheckBoxFocusVisual">
    <Setter Property="Control.Template">
      <Setter.Value>
        <ControlTemplate>
          <Rectangle Margin="1"
                     SnapsToDevicePixels="true"
                     Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"
                     StrokeDashArray="1 2"
                     StrokeThickness="1" />
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
  <Style x:Key="CheckRadioFocusVisual">
    <Setter Property="Control.Template">
      <Setter.Value>
        <ControlTemplate>
          <Rectangle Margin="14,0,0,0"
                     SnapsToDevicePixels="true"
                     Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"
                     StrokeDashArray="1 2"
                     StrokeThickness="1" />
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
  <Style TargetType="{x:Type CheckBox}"
         x:Key="ContentLeftCheckBoxStyle">
    <Setter Property="Foreground"
            Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" />
    <Setter Property="Background"
            Value="{StaticResource CheckBoxFillNormal}" />
    <Setter Property="BorderBrush"
            Value="{StaticResource CheckBoxStroke}" />
    <Setter Property="BorderThickness"
            Value="1" />
    <Setter Property="FocusVisualStyle"
            Value="{StaticResource EmptyCheckBoxFocusVisual}" />
    <Setter Property="VerticalContentAlignment"
            Value="Center" />
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="{x:Type CheckBox}">
          <StackPanel Orientation="Horizontal">
            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                              Margin="{TemplateBinding Padding}"
                              RecognizesAccessKey="True"
                              SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                              VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
            <BulletDecorator Background="Transparent"
                             SnapsToDevicePixels="true"
                             VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
              <BulletDecorator.Bullet>
                <Microsoft_Windows_Themes:BulletChrome Background="{TemplateBinding Background}"
                                                       BorderBrush="{TemplateBinding BorderBrush}"
                                                       IsChecked="{TemplateBinding IsChecked}"
                                                       RenderMouseOver="{TemplateBinding IsMouseOver}"
                                                       RenderPressed="{TemplateBinding IsPressed}" />
              </BulletDecorator.Bullet>
            </BulletDecorator>
          </StackPanel>
          <ControlTemplate.Triggers>
            <Trigger Property="HasContent"
                     Value="true">
              <Setter Property="FocusVisualStyle"
                      Value="{StaticResource CheckRadioFocusVisual}" />
              <Setter Property="Padding"
                      Value="0,0,4,0" />
            </Trigger>
            <Trigger Property="IsEnabled"
                     Value="false">
              <Setter Property="Foreground"
                      Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
            </Trigger>
          </ControlTemplate.Triggers>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
</ResourceDictionary>

用法：

<CheckBox Style="{StaticResource ContentLeftCheckBoxStyle}" Content="CheckBox:" />

希望有所帮助！

另一种解决方法是，在定义全新的CheckBox样式时，为了避免上面讨论的流向和大量代码的细微问题，只需使用包含Label（带有所需的CheckBox内容字符串）和CheckBox的WrapPanel（没有）内容字符串）。

<WrapPanel>
    <Label Content="Checkbox content"/>
    <CheckBox VerticalAlignment="Center" Margin="5,0,0,0"/>
</WrapPanel>

我花了两个小时，但我找到了最好的决定

<Style x:Key="TextAlignLeft" TargetType="CheckBox">
    <Style.Resources>
        <Style TargetType="Path">
            <Setter Property="FlowDirection" Value="LeftToRight" />
        </Style>
        <Style TargetType="TextBlock">
            <Setter Property="FlowDirection" Value="LeftToRight" />
        </Style>
    </Style.Resources>

    <Setter Property="FlowDirection" Value="RightToLeft" />
</Style>

Answer 6

我知道已经有一段时间了，我迟到了。但经过几个复杂的答案并在互联网上搜索了很多，我终于找到了最简单的方法来实现这一点，而不会扭曲来自here的嘀嗒声。

<CheckBox Content="Checked" FlowDirection="RightToLeft">
    <CheckBox.Resources>
        <Style TargetType="{x:Type Path}">
            <Setter Property="FlowDirection" Value="LeftToRight" />
        </Style>
    </CheckBox.Resources>
</CheckBox>

结果：

最简单的方法是使用堆栈面板：

            <StackPanel Orientation="Horizontal">
                <TextBlock Text="Some Text"/>
                <CheckBox  />
            </StackPanel>

您可以编辑复选框模板，然后可以将文本块放在矩形的前面
