如何设计WPF单选按钮中的样式,如复选框

我想要一个类似于复选框的单选按钮,所以我在Dictionary文件中定义一个样式,如:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:WpfCheckBoxLikeRadiobutton">

<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RadioButton}">
                <Grid>
                    <CheckBox
                        IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, 
                        Path=IsChecked, Mode=TwoWay}"
                        IsHitTestVisible="False" />
                    <CheckBox
                    IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, 
                    Path=IsChecked, Mode=TwoWay}" Opacity="0"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

并将其合并到app.xaml文件中,如下所示

<Application x:Class="WpfCheckBoxLikeRadiobutton.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:WpfCheckBoxLikeRadiobutton"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Dictionary1.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

然后在我的窗口中使用它

<GroupBox Margin="5" Padding="5">
        <StackPanel >
            <CheckBox Content="this is checkbox" />
            <RadioButton Content="this is first radio button" Style="{DynamicResource MyRadioButton}"/>
            <RadioButton Content="this is Second radio button" Style="{DynamicResource MyRadioButton}"/>
            <RadioButton Content="this is third radio button" Style="{DynamicResource MyRadioButton}"/>
        </StackPanel>
    </GroupBox>

但在为radiobutton指定样式后,该内容将消失。 我的风格有什么问题?

这是因为您忽略了ControlTemplate中控件的内容。你的风格应该是这样的:

<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type RadioButton}">
            <Grid>
                <CheckBox
                    IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, 
                                Path=IsChecked, Mode=TwoWay}"
                    IsHitTestVisible="False" Content="{TemplateBinding Content}" />
                <CheckBox
                IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, 
                            Path=IsChecked, Mode=TwoWay}"   
                Content="{TemplateBinding Content}" Opacity="0"/>
            </Grid>
        </ControlTemplate>
    </Setter.Value>
</Setter>

我认为你甚至可以做得更简单,让它看起来更好,只需点击右键 - &gt; EditStyle并用模板中的矩形替换每个椭圆。有很多动画你不会以这种方式松散。

这就是我所做的看起来不错,你也可以复制&#34; CheckIcon&#34;从复选框样式中,如果您愿意,它看起来就像一个复选框。

除了Verbon的回答,我还有一个样式,其中复选框看起来像单选按钮。<Style x:Key="CheckBoxRadioButtonStyle" TargetType="CheckBox"> <Setter Property="Background" Value="Transparent"/> <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/> <Setter Property="Padding" Value="3"/> <Setter Property="HorizontalAlignment" Value="Center"/> <Setter Property="VerticalAlignment" Value="Center"/> <Setter Property="HorizontalContentAlignment" Value="Left"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/> <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/> <Setter Property="MinWidth" Value="30"/> <Setter Property="UseSystemFocusVisuals" Value="True"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="CheckBox"> <Grid BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"> <Grid.ColumnDefinitions> <ColumnDefinition Width="20"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="PointerOver"> </VisualState> <VisualState x:Name="Pressed"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Stroke" Storyboard.TargetName="OuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightBaseMediumBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Stroke" Storyboard.TargetName="CheckOuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightBaseMediumBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Fill" Storyboard.TargetName="CheckOuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightTransparentBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Fill" Storyboard.TargetName="CheckGlyph"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightAltBaseMediumBrush}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Disabled"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Stroke" Storyboard.TargetName="OuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlDisabledBaseLowBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Stroke" Storyboard.TargetName="CheckOuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlDisabledBaseLowBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Fill" Storyboard.TargetName="CheckOuterEllipse"> <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Fill" Storyboard.TargetName="CheckGlyph"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlDisabledBaseLowBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter"> <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlDisabledBaseLowBrush}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="CheckStates"> <VisualState x:Name="Checked"> <Storyboard> <DoubleAnimation Duration="1" To="0" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/> <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="OuterEllipse"/> <DoubleAnimation Duration="0" To="0" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckOuterEllipse"/> </Storyboard> </VisualState> <VisualState x:Name="Unchecked"> <Storyboard> <DoubleAnimation Duration="0" To="0" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="OuterEllipse"/> <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckOuterEllipse"/> <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/> </Storyboard> </VisualState> <VisualState x:Name="Indeterminate"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid Height="32" VerticalAlignment="Top"> <Ellipse x:Name="OuterEllipse" Height="20" Fill="Green" Stroke="Green" Opacity="0" StrokeThickness="{ThemeResource RadioButtonBorderThemeThickness}" UseLayoutRounding="False" Width="20"/> <Ellipse x:Name="CheckOuterEllipse" Fill="White" Height="20" Opacity="1" Stroke="Gray" StrokeThickness="{ThemeResource RadioButtonBorderThemeThickness}" UseLayoutRounding="False" Width="20"/> <Ellipse x:Name="CheckGlyph" Fill="White" Height="12" Opacity="1" UseLayoutRounding="False" Width="12"/> </Grid> <ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" Content="{TemplateBinding Content}" Grid.Column="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" TextWrapping="Wrap" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>

然后将上述风格合并到Verbon的风格中:

<Grid>
                        <CheckBox  IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsChecked, Mode=TwoWay}" IsHitTestVisible="False" Content="{TemplateBinding Content}" Style="{StaticResource CheckBoxRadioButtonStyle}"/>
                        <CheckBox  IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsChecked, Mode=TwoWay}" Content="{TemplateBinding Content}" Opacity="0" Style="{StaticResource CheckBoxRadioButtonStyle}"/>
                    </Grid>
