先上效果图：

这个控件其实是俩个RadioButton，通过样式就可以实现。

样式资源：

 <Style x:Key="Tong_Yong_RadioButtonStyle" TargetType="{x:Type RadioButton}">
                 <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" />
                 <Setter Property="Background" Value="White" />
                 <Setter Property="BorderThickness" Value="" />
                 <Setter Property="HorizontalContentAlignment" Value="Center" />
                 <Setter Property="VerticalContentAlignment" Value="Center" />
                 <Setter Property="Padding" Value="" />
                 <Setter Property="Margin" Value="10,10,0,0" />
                 <Setter Property="Cursor" Value="Hand" />
                 <Setter Property="Height" Value="{Binding Height}" />
                 <Setter Property="Width" Value="{Binding Width}" />
                 <Setter Property="Cursor" Value="Hand" />
                 <Setter Property="Template">
                 <Setter.Value>
                         <ControlTemplate TargetType="{x:Type RadioButton}">
                             <Grid>
                                 <!--  选中或者鼠标移入颜色  -->
                                 <Grid
                                     x:Name="B"
                                     Background="#0099ff"
                                     Visibility="Collapsed" />
                                 <!--  默认颜色  -->
                                 <Grid x:Name="A" Background="{TemplateBinding Background}" />

                                 <ContentPresenter
                                     x:Name="b"
                                     HorizontalAlignment="Center"
                                     VerticalAlignment="Center"
                                     TextBlock.Foreground="White" />
                                 <ContentPresenter
                                     x:Name="a"
                                     HorizontalAlignment="Center"
                                     VerticalAlignment="Center"
                                     TextBlock.Foreground="Black" />
                             </Grid>
  　　　　　　　　　　　　　　　　<ControlTemplate.Triggers>
                                 <Trigger Property="IsChecked" Value="True">
                                     <Setter TargetName="A" Property="Visibility" Value="Collapsed" />
                                     <Setter TargetName="B" Property="Visibility" Value="Visible" />
                                     <Setter TargetName="a" Property="Visibility" Value="Collapsed" />
                                     <Setter TargetName="b" Property="Visibility" Value="Visible" />
                                 </Trigger>
                             </ControlTemplate.Triggers>
                         </ControlTemplate>
                     </Setter.Value>
                 </Setter>
             </Style>

2.引用样式

 <RadioButton
                                Width=""
                                Margin=""
                                Content="开"
                                Foreground="Black"
                                Style="{DynamicResource Tong_Yong_RadioButtonStyle}" />
                            <RadioButton
                                Width=""
                                Margin=""
                                Content="关"
                                Foreground="Black"
                                IsChecked="True"
                                Style="{DynamicResource Tong_Yong_RadioButtonStyle}" />
