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));

                    node.CustomAttributes.Add(new ConfigItem("SAVETYPE", item.SAVETYPE, ParameterMode.Value));

                    node.Leaf = true;

                    //加载子节点

                    GetSubNode(node, listALL);

                    if (node.Children.Count > )

                        node.Leaf = false;

                    root.Children.Add(node);

                }

            }

        }
