请问DEVExpress TreeList 控件怎么绑定数据？ 是哪个事件触发绑定的？谢谢了！

参考技术A 跟C#里面自带的那个一样的绑定，时间是databound事件 参考技术B 绑定
private void initTree()


string sqltree = "select fitemid id,fnumber 代码,fname 名称,fparentid parentid from T_ITEM WHERE FITEMCLASSID=4 and fdeleted=0 and substring(fnumber,1,1)='8' and fdetail=0";
DataTable dtTree = SqlFunc.ExecSQL(sqltree);
treeList1.DataSource = dtTree;
treeList1.Columns["id"].Visible = false;
treeList1.Columns["parentid"].Visible = false;
treeList1.ExpandAll();
gridView1.OptionsView.AllowCellMerge = true;

单击事件
private void treeList1_FocusedNodeChanged(object sender, DevExpress.XtraTreeList.FocusedNodeChangedEventArgs e)

DataRowView drv = (DataRowView)treeList1.GetDataRecordByNode(treeList1.FocusedNode);
DataRow dr = drv.Row;
int p = Convert.ToInt32(dr[0]);
