如何在Asp中動態生成TreeView？

使用微軟。Web . UI.WebControls//添加對控件private void GetTreeView()//程序start { try { string strql = " select distinct Menu _ id，Menu _ name from docmodulemanager where Menu _ level = 1和sn in ("+All。子串(0，全部。長度-1)。ToString()+")；Oracle dataadapter obj adapter = new Oracle dataadapter(strSql，obj conn)；數據集ds =新數據集()；ds。clear()；objAdapter。Fill(ds，“temp”)；數據表dt = ds。表格[" temp "]；樹形視圖1。nodes . Clear()；//建立根節點並遍歷。foreach(數據行dr in dt。rows){ TreeNode Root = new TreeNode()；根。Text = dr["Menu_name"]。ToString()；樹形視圖1。Nodes.Add(根)；//建立根節點字符串str = "SELECT Menu_name，menu_addr，sn from docmodulemanager where upper _ id = ' "+dr[" Menu _ id "]。ToString() +'和sn in ("+menu_sn。子串(0，menu_sn。長度-1)。ToString()+"+"+" order by menu _ id，child _ id "；Oracle dataadapter objAdapterNode = new Oracle dataadapter(str，obj conn)；數據集dsNode =新數據集()；dsNode。clear()；objAdapterNode。Fill(dsNode，“tempNode”)；數據表dtNode = dsNode。表[" tempNode "]；//創建子節點並遍歷。foreach(dtNode中的DataRow drNode。rows){ TreeNode Node = new TreeNode()；節點。Text = drNode["Menu_name"]。ToString()；節點。Target = ā8ǐ8？”main bottom”；string Path = drNode["menu_addr"]。ToString()；int menusn = Convert。ToInt32(drNode["sn"]。ToString())；節點。NavigateUrl = "Transfer.aspx"+"？menu _ addr = "+Path；根。Nodes.Add(節點)；//創建子節點} } Catch { response . write(" alert('您沒有菜單項可操作，請聯系管理員！');)；}最後{ if (objConn。State.ToString()。Equals ("Open")) objConn。close()；} }
