Windows应用商店列表视图

Question

我有一个ListView，它的项目是一组RadioButtons，当我从第一个项目中选择要说的单选按钮时，ListView绑定到100个字符串的列表，也许第二个和第三个项目一切正常。 但是，当我滚动到第50个项目时，或者当我在没有出现在第一页的任何项目中选择单选按钮时，只是取消选择了在前一页中的第一个项目，就好像listview再次渲染了这些项目并忘了可能的操纵

        <ListView ItemsSource="{Binding}" x:Name="list" VirtualizingStackPanel.VirtualizationMode="Standard">
        <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <RadioButton Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1" Click="x1_Click"  />
                    <RadioButton x:Name="x2" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1" Click="x1_Click"  />
                    <RadioButton x:Name="x3" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1"  Click="x1_Click"  />
                    <RadioButton x:Name="x4" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1"  Click="x1_Click"  />
                    <RadioButton x:Name="x5" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1"  Click="x1_Click"  />
                    <RadioButton x:Name="x6" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1"  Click="x1_Click"  />
                    <RadioButton x:Name="x7" Template="{StaticResource CheckBoxTemplate2}" Foreground="Orange" Content="Test" Label="YOK" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Canvas.ZIndex="12" FontSize="14" FontWeight="Bold" FontFamily="Advantage-SemiBold"  Checked="BetRadioButton_Checked_1"  Click="x1_Click"  />

                </StackPanel>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>



list.DataContext = new List<String>() { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", };

我猜您的问题是所有RadioButton都具有相同的GroupName 。 单选按钮的默认GroupName为null，因此所有RadioButtons都具有相同的GroupName 。 要解决此问题，您需要为ListView每个项目提供唯一的GroupName 。 此外，所有“已Checked属性都绑定到同一属性。 您是否要使用CheckBox而不是RadioButton ？
