树形导航列表与菜单列表实现同步

public void BindTree()        {                 DataSet ds = new DataSet();            SqlServerDAL.MenuTree MT=new SqlServerDAL.MenuTree();            ds=MT.GetCategory();            treeview_hr.ImageList = imgtreeview;            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)            {                //顶部菜单                ToolStripMenuItem item= new ToolStripMenuItem(ds.Tables[0].Rows[i]["name"].ToString().Trim());                menuStrip_hr.Items.Add(item);                //树形菜单                DataSet Cds = MT.GetcData(int.Parse(ds.Tables[0].Rows[i]["cID"].ToString()));                TreeNode[] ChildNodes = new TreeNode[Cds.Tables[0].Rows.Count];                for (int j = 0; j < Cds.Tables[0].Rows.Count; j++)                {                    //树形二级菜单                    ChildNodes[j] = new TreeNode();                    ChildNodes[j].Text = Cds.Tables[0].Rows[j]["title"].ToString().Trim ();                    ChildNodes[j].Tag = Cds.Tables[0].Rows[j]["dataID"].ToString().Trim ();                    ChildNodes[j].ImageIndex = 1;                    //顶部二级菜单                                   ToolStripMenuItem childitem = new ToolStripMenuItem(Cds.Tables[0].Rows[j]["title"].ToString().Trim());                    item.DropDownItems.Add(childitem);                    childitem.Click += new EventHandler(childitem_Click);                          }                                TreeNode node = new TreeNode(ds.Tables[0].Rows[i]["name"].ToString().Trim (), ChildNodes);                               treeview_hr.Nodes.Add(node);            }                     }        private void childitem_Click(object sender, EventArgs e)        {            HR.ModuleClass.MyModule mymodule = new HR.ModuleClass.MyModule();            mymodule.Show_Form(((ToolStripMenuItem)sender).Text);         }        private void frm_main_Load(object sender, EventArgs e)        {            this.toolStripStatuslbldate.Text="当前系统日期: "+ DateTime .Now.ToShortDateString();            this.toolStripStatuslbluser.Text = "当前用户: "+Utility.userloginfor.username.ToString();                  }        private void treeview_hr_AfterSelect(object sender, TreeViewEventArgs e)        {            TreeNode node = e.Node;            if (node.Level == 1) //子节点            {                HR.ModuleClass.MyModule mymodule = new HR.ModuleClass.MyModule();                mymodule.Show_Form(node.Text.Trim());                treeview_hr.SelectedImageIndex = 1;            }            else            {                treeview_hr.SelectedImageIndex = 0;            }首先需要为窗体添加ImageList，然后把所有需要显示的图标加载其中。     然后用此去初始化treeview的ImageList属性注意：ImageList也是个控件。从工具箱找到ImageList   拖到你的TreeView上   然后就可以设置了
