  private void FrmLeftMenu_Load(object sender, EventArgs e)
        {
            DataTable dt=stu.GetMain().Tables[0];            
            CreateGroup(dt, "MainName", "ChildName",nbcLeft);          
        }

 /// <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navbargroup
            nbcLeft.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 navbargoup
                DevExpress.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;
                }
            }
        
        }

            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;
