binding的有关问题

binding的问题

<Grid>
                        <phone:LongListSelector>
                            <phone:LongListSelector.ItemTemplate ItemsSource="{Binding Names}" >
                                <DataTemplate>
                                    <StackPanel >
                                    <TextBlock Text="{Binding ID}" />
                                    <TextBlock Text="{Binding Name}" />
                                    </StackPanel>
                                </DataTemplate>
                            </phone:LongListSelector.ItemTemplate>
                        </phone:LongListSelector>
                    </Grid>

grid的datacontext

class Test
{
public string id;
public List<string> Names;
}

如何实现这种绑定啊。。内层的list里面需要外面datacontext的属性。。。。
[解决办法]
你可以把class A的一个实例当作class B的一个属性。然后只设置grid的data context.
