Windows应用商店列表视图

Question

I've a ListView that its items are a set of RadioButtons, the ListView is bonded to a list of 100 strings when I select a radio button let say from the first item , and maybe the second and the third, everything work just fine. But when I scroll for the maybe the 50th item or when I select a radiobutton in any item not appearing the first page, the selection of the first item which are in the previous page is just deselected, as if the listview rendered the items again and forgot about may manipulation

        <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", };

I'm guessing your problem is that all of your RadioButton s have the same GroupName . The default GroupName for radio buttons is null, so all your RadioButtons have the same GroupName . To fix this you need to come up with a unique GroupName for each item in your ListView . Also, all of your Checked properties are bound to the same property. Are you maybe wanting a CheckBox instead of a RadioButton ?
