我制作了一个样式RadioButtonToggleButtonStyle,如下所示

  <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                        xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
                        d1p1:Ignorable="d" 
                        xmlns:d1p1="http://schemas.openxmlformats.org/markup-compatibility/2006"                    
                        xmlns:local="clr-namespace:TeachpendantControl">

        <Style x:Key="RadioButtonToggleButtonStyle" 
               BasedOn="{StaticResource {x:Type ToggleButton}}"
               TargetType="{x:Type RadioButton}">
            <Style.Triggers>
                <Trigger Property="IsChecked" Value="True">
                    <Setter Property="Background" Value="Gold"/>
                </Trigger>
            </Style.Triggers>
        </Style>   
    </ResourceDictionary>

我是这样用的

 <ListBox  Grid.Column="0" Grid.Row="0" Grid.RowSpan="10" ItemsSource="{Binding LeftPaneViewModelInfoItems, UpdateSourceTrigger=PropertyChanged}" Background="Transparent" SelectedItem="{Binding SelectedViewModelInfoItem}">
                    <ListBox.ItemContainerStyle>
                        <Style TargetType="{x:Type ListBoxItem}">
                            <Setter Property="Background" Value="Transparent" />
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                                        <ContentPresenter />
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </ListBox.ItemContainerStyle>
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <RadioButton 
                                Content="{Binding Text}"                                     
                                GroupName="DisplayPage"
                                IsChecked="{Binding IsSelected, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}"
                                Style="{StaticResource RadioButtonToggleButtonStyle}"                                     
                                >                                    
                            </RadioButton>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>

运行应用程序时,
复选框
显示为
切换按钮
(但在设计模式下它显示为
复选框

但是当选中
复选框
(样式为
切换按钮
)时,我没有得到金色背景。此外,Visual Studio(2015)在资源文件中抱怨说,无法解决资源{x:Type ToggleButton}


任何人都可以解释为什么这不起作用(以及如何解决)

您需要修改
控制模板
,以便能够更改
切换按钮的
背景

默认的
ControlTemplate
包含的硬编码值优先于在
样式中指定的值

通过在Visual Studio或Blend中的设计模式中右键单击
切换按钮
,然后选择编辑模板->编辑副本,然后根据需要编辑副本,可以将默认模板复制到项目中。试试这个:

<Style x:Key="RadioButtonToggleButtonStyle" TargetType="{x:Type ToggleButton}">
    <Style.Resources>
        <Style x:Key="FocusVisual">
            <Setter Property="Control.Template">

                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

谢谢,这是一个打字错误,我不应该拘泥于这种风格。更改它有助于现在在设计模式下查看切换按钮,并删除了错误消息。问题仍然存在,在IsChecked上背景没有更改。是的,我已经在Checked状态下删除了键入,默认的ToggleButton模板没有显示任何使用Background属性的元素。您必须修改ToggleButton模板。谢谢,是的,下面的样式和ToggleButton模板解决了这个问题。谢谢Visual Studio中的编辑->复制的额外信息,我只认为在Blend中可以做到这一点。
