wpf - WPF 中的切换按钮

Question

我是 wpf 的新手。我想创建像这样的切换按钮



我怎样才能做到这一点。我是否需要使用两个按钮，点击每个按钮时我需要禁用另一个按钮。或者wpf中还有其他类似切换按钮的东西。实现这一目标的最佳方法是什么.. 任何建议表示赞赏。谢谢

这是一个快速版本。诀窍是使用样式。

风格:

<Style x:Key="ButtonFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#F3F3F3" Offset="0"/>
        <GradientStop Color="#EBEBEB" Offset="0.5"/>
        <GradientStop Color="#DDDDDD" Offset="0.5"/>
        <GradientStop Color="#CDCDCD" Offset="1"/>
    </LinearGradientBrush>
    <SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/>
    <Style x:Key="ToggleButtonStyle1" TargetType="{x:Type ToggleButton}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
        <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
        <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}">
                    <StackPanel Orientation="Horizontal">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Border x:Name="on" Width="25" Height="25" Background="LightGray" CornerRadius="2,0,0,4" Margin="10,0,0,0">
                            <TextBlock x:Name="onText" Text="On" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                        <Border x:Name="off" Width="25" Height="25" Background="LightGray" CornerRadius="0,2,4,0">
                            <TextBlock x:Name="offText" Text="Off" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                    </StackPanel>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="#ADADAD"/>
                        </Trigger>
                        <Trigger Property="IsChecked" Value="true">
                            <Setter TargetName="on" Property="Background" Value="LightBlue"/>
                            <Setter TargetName="onText" Property="Foreground" Value="White"/>
                        </Trigger>
                        <Trigger Property="IsChecked" Value="False">
                            <Setter TargetName="off" Property="Background" Value="LightBlue"/>
                            <Setter TargetName="offText" Property="Foreground" Value="White"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

切换按钮调用:

    <ToggleButton 
        Content="ON LINE MODE" 
        Style="{StaticResource ToggleButtonStyle1}"/>
