Silverlight GridView(DataGrid)嵌套多张表

可以通过设置DataGrid的HierarchyChildTemplate来实现表的主从嵌套，不过这里设置完成后所有嵌套的表的结构都是一样了，但是我需要不一样的结构，由一下代码完成。

注1：DataGrid的嵌套是直接点击后下拉出来的，平时看不出有嵌套的情况。但是我想在要那种树状结构，所以这里直接用了RAD第三方控件的插件，RadGridView，他们都能实现，只是显示的效果有点不一样。

注2：DLL

XAML:

<telerik:RadGridView x:Name="radTree" 
                         ShowGroupPanel="False"
                         CanUserFreezeColumns="False" 
                         GridLinesVisibility="Both" 
                         IsReadOnly="True" 
                         AutoGenerateColumns="False"
                         IsFilteringallowed="False"
                         RowIndicatorVisibility="Collapsed" Margin="0,2">
            <telerik:RadGridView.ChildTableDeFinitions>
                <telerik:GridViewTableDeFinition/>
            </telerik:RadGridView.ChildTableDeFinitions>
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="名称" DataMemberBinding="{Binding Name}"  MinWidth="100"/>
                <telerik:GridViewDataColumn Header="开始时间" DataMemberBinding="{Binding StartTime}" MinWidth="120" />
                <telerik:GridViewDataColumn Header="结束时间" DataMemberBinding="{Binding EndTime}" MinWidth="120" />
            </telerik:RadGridView.Columns>
            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView  ItemsSource="{Binding Items}" 
                                    ShowGroupPanel="False"
                                    CanUserFreezeColumns="False" 
                                    GridLinesVisibility="Horizontal" 
                                    IsReadOnly="True" 
                                    AutoGenerateColumns="False"
                                    IsFilteringallowed="False"  
                                    ShowColumnHeaders="False" BorderThickness="0">
                        <telerik:RadGridView.ChildTableDeFinitions>
                            <telerik:GridViewTableDeFinition/>
                        </telerik:RadGridView.ChildTableDeFinitions>
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Name}" MinWidth="100"/>
                        </telerik:RadGridView.Columns>
                        <telerik:RadGridView.HierarchyChildTemplate>
                            <DataTemplate>
                                <classes:MyDataGrid DataSources="{Binding Datas}" Visibility="Collapsed"/>
                            </DataTemplate>
                        </telerik:RadGridView.HierarchyChildTemplate>
                    </telerik:RadGridView>
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>
        </telerik:RadGridView>

后台：

 public partial class MainPage
    {
        public MainPage()
        {
            InitializeComponent();
            Init();
        }

        private void Init()
        {
            var fruit = new List<string> { "苹果","橘子","香蕉" };
            var municipality = new List<string> { "北京","天津","上海","重庆" };
            var province = new List<string> { "黑龙江","吉林","辽宁" };
            var leafItem1 = new LeafItem { Name = "水果",Datas = CreateNewDatas(fruit) };
            var leafItem2 = new LeafItem { Name = "直辖市",Datas = CreateNewDatas(municipality) };
            var leafItem3 = new LeafItem { Name = "省份",Datas = CreateNewDatas(province) };
            var leaf1 = new Leaf { Name = "总结点1",StartTime = "2013-06-01",EndTime = "2013-06-02",Items = new List<LeafItem> { leafItem1 } };
            var leaf2 = new Leaf { Name = "总结点2",StartTime = "2013-06-02",EndTime = "2013-06-03",Items = new List<LeafItem> { leafItem2,leafItem3 } };
            radTree.ItemsSource = new List<Leaf> { leaf1,leaf2 };
        }

        private static List<Dictionary<string,string>> CreateNewDatas(List<string> list)
        {
            var random = new Random();
            var datas = new List<Dictionary<string,string>>();
            var count = random.Next(10);
            for (var i = 0; i < count; i++)
            {
                datas.Add(list.ToDictionary(str => str,str => random.Next(50).ToString(CultureInfo.InvariantCulture)));
            }
            return datas;
        }
    }

这里为了实现不同的从属表结构，所以自定义了一个控件，继承自DataGrid。这里用到了上一篇里面DataGrid 绑定 字典集合。

 public class MyDataGrid : DataGrid
    {
        #region 数据值

        public static readonly DependencyProperty DataSourcesProperty =
        DependencyProperty.Register("DataSources",typeof(List<Dictionary<string,string>>),typeof(MyDataGrid),new PropertyMetadata(null));
        public List<Dictionary<string,string>> DataSources
        {
            get { return (List<Dictionary<string,string>>)GetValue(DataSourcesProperty); }
            set { SetValue(DataSourcesProperty,value); }
        }

        #endregion

        public MyDataGrid()
        {
            DefaultStyleKey = typeof(DataGrid);
            Loaded += MyDataGrid_Loaded;
        }

        void MyDataGrid_Loaded(object sender,RoutedEventArgs e)
        {
            if (DataSources == null || DataSources.Count == 0) return;
            var first = DataSources.First();
            foreach (var node in first)
            {
                Columns.Add(new DataGridTextColumn { Header = node.Key,Binding = new Binding(string.Format("[{0}]",node.Key)) });
            }
            AutoGenerateColumns = false;
            ItemsSource = DataSources;
            Visibility = Visibility.Visible;
        }
    }

再设置一个用于绑定的类

 public class LeafItem
    {
        public string Name { get; set; }
        public List<Dictionary<string,string>> Datas { get; set; }
        public LeafItem()
        {
            Datas = new List<Dictionary<string,string>>();
        }
    }

    public class Leaf
    {
        public string Name { get; set; }
        public string StartTime { get; set; }
        public string EndTime { get; set; }
        public List<LeafItem> Items { get; set; }
        public Leaf()
        {
            Items = new List<LeafItem>();
        }
    }
