具体实现：
一、
using DevExpress.XtraNavBar;二、
从窗体上拖一个 NavBarControl 控件 命名为：nbcLeft
三、窗体OnLoad 事件
private void FrmLeftMenu_Load(object sender, EventArgs e){DataTable dt=stu.GetMain().Tables[0];CreateGroup(dt, "MainName", "ChildName",nbcLeft);}NavBarControl 调用方法：
/// <summary>/// NavBarControl 数据填充/// </summary>/// <param name="dt">含有主菜单(子菜单)的表</param>/// <param name="mainColumnsName">主菜单名称</param>/// <param name="childColumnsName">子菜单名称</param>/// <param name="nbc">NavBarControl 控件名称</param>private void CreateGroup(DataTable dt,string mainColumnsName,string childColumnsName,NavBarControl nbc) {//创建之前，清空navbargroupnbcLeft.Groups.Clear();//过滤重复记录DataTable dt1 = dt.DefaultView.ToTable(true, mainColumnsName);if (dt1.Rows.Count < 1) {return;}DataRow[] drs = dt1.Select();int i = 0;//foreach (DataRow dr in drs) {i++;//添加 navbargoupDevExpress.XtraNavBar.NavBarGroup nbg = new NavBarGroup();nbg.Caption = dr[0].ToString();nbg.GroupClientHeight = 60;nbc.Groups.Add(nbg);//添加子项//根据主菜单项名称 获取所属的所有子项string abc=mainColumnsName +"='"+ nbg.Caption+"'";DataRow[] drsChild = dt.Select(abc);if (drsChild.Length < 1) {continue;}CreateGroupChild(drsChild,nbg,childColumnsName);//加载时，第一个是展开的if (i == 1) {nbg.Expanded = true;}}}/// <summary>/// 添加子项/// </summary>/// <param name="drs">子菜单表</param>/// <param name="nbg">NavBarGroup 主菜单项</param>private void CreateGroupChild(DataRow[] drs, DevExpress.XtraNavBar.NavBarGroup nbg,string childColumnsName) {foreach (DataRow dr in drs) {//给子项赋值DevExpress.XtraNavBar.NavBarItem nbi = new NavBarItem();nbi.Caption = dr[childColumnsName].ToString();//nbi.Appearance.BackColor = Color.Yellow;////子菜单图片//nbi.SmallImage=new Bitmap(@"C:\Users\Thinkpad\Pictures\美图\psu.jpg");nbg.ItemLinks.Add(nbi);nbi.LinkClicked += new DevExpress.XtraNavBar.NavBarLinkEventHandler(Nbi_LinkClicked);}}//单击事件private void Nbi_LinkClicked(object sender, DevExpress.XtraNavBar.NavBarLinkEventArgs e) {//点击子项，，执行…..}说明：数据表举例：
