后台绑定数据源：

        private void BuildTree()
        {
            Ext.Net.Node root = new Ext.Net.Node();
            root.Text = "Root";
            IndexTableTree.Root.Add(root);
             List<EXTTreeNode> listALL = GetData();
            List<EXTTreeNode> list = GetData().FindAll(p=>p.pId=="");
            if (list!= null &&list.Count>)
            {
                foreach (var item in list)
                {
                    Ext.Net.Node node = new Ext.Net.Node();
                    node.Text = item.name;
                    node.NodeID = item.id;
                    if (!string.IsNullOrWhiteSpace(noid))
                    {
                        string flag = "";
                        ifMyChild(item.id, listALL, noid, ref flag);
                        if (flag=="")
                        {
                            node.Expanded = true;
                        }
                    }
                    //添加自定义属性
                    node.CustomAttributes.Add(new ConfigItem("S_CODE", item.CODE, ParameterMode.Value));
                    node.CustomAttributes.Add(new ConfigItem("BASETYPE", item.BASETYPE, ParameterMode.Value));

                    GetSubNode(node, listALL);
                    if (node.Children.Count > )
                        node.Leaf = false;
                    root.Children.Add(node);
                }
            }
        }
