WPF 自定义RadioButton样式

一、RadioButton基本样式

RadioButton基本样式包含两种状态，这里也是使用两张图片来代替两种状态，当然你也可以通过IconFont或Path来替换这两种状态。

效果如下：

样式代码如下：

<Style x:Key="radBase" TargetType="RadioButton">
            <Setter Property="IsChecked" Value="False"/>
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="Foreground" Value="#555"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="RadioButton">
                        <DockPanel  Background="{TemplateBinding Background}" ToolTip="{TemplateBinding Content}" LastChildFill="False" Width="{TemplateBinding Width}">
                            <Image Margin="2 0 0 0" DockPanel.Dock="Left" x:Name="_img"  Stretch="None" Source="/Images/rdo_no.png"/>
                            <TextBlock DockPanel.Dock="Left" Margin="3 0 0 0" VerticalAlignment="Center" Foreground="{TemplateBinding Foreground}" Text="{TemplateBinding Content}" />
                        </DockPanel>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsChecked" Value="true">
                                <Setter TargetName="_img" Property="Source" Value="/Images/rdo_yes.png"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                  </ControlTemplate>
             </Setter.Value>
        </Setter>
 </Style>

二、RadioButton其它样式

先看效果图：

这种样式一般用于突出用户选择。这里的每个选项都是填充的颜色，你也可以选择填充文字内容。

样式代码如下：

<Style x:Key="RadioThemeColor" TargetType="RadioButton">
            <Setter Property="Margin" Value="1"/>
            <Setter Property="Background" Value="#e892ca"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="RadioButton">
                        <Grid Background="{TemplateBinding Background}" Width="62" Height="35" Margin="{TemplateBinding Margin}">
                            <Border x:Name="_borderOver" Background="Transparent" BorderBrush="Transparent" BorderThickness="1" Margin="1">

                            </Border>
                            <Border x:Name="_borderChecked" Visibility="Collapsed" Background="#88000000" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="15" Height="15">
                                <Path Data="M0,5 5,10 13,1" Margin="2 2 0 0" Stroke="White" StrokeThickness="1"/>
                            </Border>
                        </Grid>
                        <ControlTemplate.Triggers>
                            <Trigger Property="HasContent" Value="True">
                                <Setter Property="FocusVisualStyle">
                                    <Setter.Value>
                                        <Style>
                                            <Setter Property="Control.Template">
                                                <Setter.Value>
                                                    <ControlTemplate>
                                                        <Rectangle Margin="14,0,0,0" SnapsToDevicePixels="True" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                                                    </ControlTemplate>
                                                </Setter.Value>
                                            </Setter>
                                        </Style>
                                    </Setter.Value>
                                </Setter>

                            </Trigger>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="BorderBrush" TargetName="_borderOver" Value="White"/>
                            </Trigger>
                            <Trigger Property="IsChecked" Value="True">
                                <Setter Property="Visibility" TargetName="_borderChecked" Value="Visible"/>
                            </Trigger>
                       </ControlTemplate.Triggers>
                  </ControlTemplate>
