silverlight中RadioButton在DataGrid的单选

与之前的silverlight中CheckBox在DataGrid的全选/取消 一样很在编程的中经常用到RadioButton控件用于在DataGrid或Repeater控件中的数据选择

在此与各位分享RadioButton的用法 如果还有好方法，望留言相互学习：

demo 如下

XAML 为

 

<Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="20"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="30"/>
            </Grid.RowDefinitions>
            <data:DataGrid x:Name="ContentGrid" Grid.Row="1"  AutoGenerateColumns="False">
            <data:DataGrid.Columns>
                <data:DataGridTemplateColumn Header="选择">
                    <data:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <RadioButton x:Name="ck" HorizontalAlignment="Center" Click="ck_Click" Tag="{Binding ID}" GroupName="SelectedItem"></RadioButton>
                            </StackPanel>
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellTemplate>
                </data:DataGridTemplateColumn>
                <data:DataGridTextColumn  Header="编号"  Binding="{Binding ID}" />
                <data:DataGridTextColumn  Header="名称"  Binding="{Binding Name}" />
                <data:DataGridTextColumn  Header="年龄" Binding="{Binding age}" />
                <data:DataGridTextColumn  Header="性别" Binding="{Binding sex}" />
                <data:DataGridTextColumn  Header="时间" Binding="{Binding AddTime}" />
            </data:DataGrid.Columns>
        </data:DataGrid>
         <Button Content="查看选中项" Grid.Row="2" Width="60" Click="Button_Click"></Button>
        </Grid>
