RadioButton 没有聚焦时有白色背景?

RadioButton has a white background when not focused?

手动点击单选按钮时的单选按钮

当我按下另一个按钮来设置选择时的单选按钮

似乎是当单选按钮没有聚焦时,然后将这个白色方框放在周围

RB 的样式:

                            <TextBlock Margin="0,0,0,0" Foreground="#FF3E3E3E" FontFamily="Calibri" FontSize="12">
                                <ContentPresenter />
                            </TextBlock>
                        </BulletDecorator>

                        <ControlTemplate.Triggers>
                            <Trigger Property="IsChecked" Value="true">
                                <Setter TargetName="RadioMark" Property="Visibility" Value="Visible"/>
                                <Setter TargetName="RadioOuter" Property="BorderBrush" Value="Yellow" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

列表框:

        <ListBox Background="Transparent" BorderThickness="0" ItemsSource="{Binding WhatsNewList}" SelectedItem="{Binding SelectedItem}">
            <ListBox.Resources>
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
                <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
            </ListBox.Resources>                    
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Horizontal" 
                            VerticalAlignment="Center" 
                            HorizontalAlignment="Center">
                    </StackPanel>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate DataType="{x:Type local:ExampleClass}">
                    <RadioButton GroupName="Properties" Background="Transparent">
                        <RadioButton.IsChecked>
                            <Binding Path="IsSelected"
                             RelativeSource="{RelativeSource AncestorType=ListBoxItem}"
                             Mode="TwoWay" />
                        </RadioButton.IsChecked>
                    </RadioButton>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

我有一个按钮,可以通过编程方式更改列表框上的 "SelectedItem"。但是,当我单击该按钮时,它会更新选择,但一个不需要的副作用是我的单选按钮选择后面出现一个白色方框。我该如何删除它?

我发现了问题,我需要将 InactiveSelectionHighlightBrushKey 颜色更改为透明

<ListBox.Resources>
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" Opacity=".4"/>
     <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey }" Color="Transparent" Opacity=".4"/>
</ListBox.Resources>
