wpf - 将嵌套列表框绑定(bind)到嵌套列表？

Question

我有以下 ViewModel-Property:

public List<List<string>> Names .... //It's a dependency property

在我看来，我想要一个 ItemsControl有一个 ItemsControl :

 <ItemsControl ItemsSource="{Binding Names}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <ItemsControl ItemsSource="{Binding ?????}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <Label Text="{Binding ??????}" />
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

如何绑定(bind)到 List 的项目?在上面的代码示例中，我将其标记为 ?????

只需使用绑定(bind)到当前绑定(bind)源:

ItemsSource="{Binding}"

请参阅下面的一些评论:

<ItemsControl ItemsSource="{Binding Names}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <! -- Here is the current binding source will be inner
                      List<string> 
                -->
                <ItemsControl ItemsSource="{Binding}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>

                    <! -- Here is the current binding wource will be 
                          a string value from the inner List<string>
                    -->
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <Label Text="{Binding}" />
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
