silverlight Treeview分层数据绑定 三层

建筑类别集合Collection里包含区域的集合RegionCollection，区域集合又包含子区children集合。建筑类别名CategoryName，区域名Name。做如下绑定。

 <StackPanel>
            <StackPanel.Resources>

                <sdk:HierarchicalDataTemplate x:Key="Child" ItemsSource="{Binding Children}">
                    <TextBlock Text="{Binding Name}"/>
                </sdk:HierarchicalDataTemplate>
                <sdk:HierarchicalDataTemplate x:Key="Category"
                                              ItemsSource="{Binding RegionCollection}"
                                              ItemTemplate="{StaticResource Child}">
                    <TextBlock Text="{Binding CategoryName}"/>
                </sdk:HierarchicalDataTemplate>
            </StackPanel.Resources>

        <sdk:TreeView  Height="300" Width="280" ItemsSource="{Binding}" ItemTemplate="{StaticResource Category}" x:Name="tvBuildingTree" >
            </sdk:TreeView>
        </StackPanel>
后台代码:                tvBuildingTree.ItemsSource = Collection;

效果图：
