DataTemplate中的单选按钮

我制作了一个DataTemplate，它将自动生成一些问题（从我的dataview加载）。每个问题都有四个单选按钮，我将所有四个按钮分组到GroupName上。

我的问题是-如果我有2或3个问题，则每当我检查一个问题的单选按钮时，上面问题的单选按钮都不会被选中。有人对此有解决方案吗？

这是我的XAML：

<ItemsControl Name="itmCntrl" >
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel Orientation="Horizontal" ></WrapPanel>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <StackPanel Name="stk">
                <StackPanel Margin="5,2,0,0">
                    <WrapPanel Margin="10,10,10,5" Height="Auto">
                        <TextBlock TextWrapping="Wrap" x:Name="tbC"  FontSize="18" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black" Text="Question : "/>
                        <TextBlock TextWrapping="Wrap" Text="{Binding NOIDUNG}" FontSize="18" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black"/>
                    </WrapPanel>
                    <WrapPanel Margin="10,5,10,5" Height="Auto">
                        <RadioButton x:Name="rdoA" GroupName="DA"/>
                        <TextBlock TextWrapping="Wrap" Name="A" Text="{Binding A}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                        <RadioButton x:Name="rdoB" GroupName="DA" Margin="10,0,0,0"/>
                        <TextBlock TextWrapping="Wrap" Name="B" Text="{Binding B}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                    </WrapPanel>
                    <WrapPanel Margin="10,5,10,5" Height="Auto">
                        <RadioButton x:Name="rdoC" GroupName="DA"/>
                        <TextBlock TextWrapping="Wrap" Name="C" Text="{Binding C}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                        <RadioButton x:Name="rdoD" GroupName="DA" Margin="10,0,0,0"/>
                        <TextBlock TextWrapping="Wrap" Name="D" Text="{Binding D}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                    </WrapPanel>
                </StackPanel>
            </StackPanel>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

该RadioButton.GroupNameProperty是一个DependencyProperty，因此这意味着您可以为每个组数据绑定唯一值：

<DataTemplate>
    <StackPanel Name="stk">
        <StackPanel Margin="5,2,0,0">
            <WrapPanel Margin="10,10,10,5" Height="Auto">
                <TextBlock TextWrapping="Wrap" x:Name="tbC"  FontSize="18" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black" Text="Question : "/>
                <TextBlock TextWrapping="Wrap" Text="{Binding NOIDUNG}" FontSize="18" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black"/>
            </WrapPanel>
            <WrapPanel Margin="10,5,10,5" Height="Auto">
                <RadioButton x:Name="rdoA" GroupName="{Binding GroupName}"/>
                <TextBlock TextWrapping="Wrap" Name="A" Text="{Binding A}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                <RadioButton x:Name="rdoB" GroupName="{Binding GroupName}" Margin="10,0,0,0"/>
                <TextBlock TextWrapping="Wrap" Name="B" Text="{Binding B}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
            </WrapPanel>
            <WrapPanel Margin="10,5,10,5" Height="Auto">
                <RadioButton x:Name="rdoC" GroupName="{Binding GroupName}"/>
                <TextBlock TextWrapping="Wrap" Name="C" Text="{Binding C}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
                <RadioButton x:Name="rdoD" GroupName="{Binding GroupName}" Margin="10,0,0,0"/>
                <TextBlock TextWrapping="Wrap" Name="D" Text="{Binding D}" FontSize="15" FontFamily="Times New Roman" FontWeight="Bold" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="Black" Margin="3,0,0,0"/>
            </WrapPanel>
        </StackPanel>
    </StackPanel>
</DataTemplate>
