DevExpress组件之——TreeList组件 yangan

        由于是第一次接触到第三方控件DevExpress中的TreeList，对其进行了进一步的研究，采用递归算法实现。做下自己熟悉第三方控件的整个过程，为和我一样处理于起步阶段的同仁们提供个参考，以下为最终效果

1、以下是代码实现

 1 //加载行政区数据
 2 public void LoadDistrictData()
 3 {
 4     string distsql = "select * from district";
 5     DataTable dataTable = _dbhelp.GetDataTable(distsql);
 6     this.tvDist.Nodes.Clear();
 7     TreeListNode treenode = tvDist.AppendNode(new object[] { "广西壮族自治区" }, null);
 8     treenode.Tag = 1000;
 9     treenode.Expanded = false;
10     CreateChildNodes(treenode, dataTable);
11     tvDist.Nodes[0].Expanded = true;
12 }
13 
14 private void CreateChildNodes(DevExpress.XtraTreeList.Nodes.TreeListNode node, DataTable dataTable)
15 {
16     DataRow[] rowList = dataTable.Select("SUPERID = '" + node.Tag + "'");
17     foreach (DataRow row in rowList)
18     {
19         TreeListNode tempNode = this.tvDist.AppendNode(new object[] { row["NAME"] }, node);
20         tempNode.Tag = row["ID"];
21         CreateChildNodes(tempNode, dataTable);
22     }
23 }
