我有2张菜单制作菜单 **页面** PathId ParentId PathUrl PathName ** PagesAssigned ** AssignedId PathId RoleId

i have these 2 table for menu Making **Pages** PathId ParentId PathUrl PathName **PagesAssigned** AssignedId PathId RoleId

SELECT [Path].Menu_Id,dbo.[Path].Path_Detail, [Path].Path_Url, [Path].Sub_Menu_Id, pagesAssigend.roleId FROM pagesAssigend INNER JOIN [Path] ON pagesAssigend.pageNo = Path.Menu_Id WHERE (dbo.pagesAssigend.roleId = 1)

Through above query i confirming a menu for a specified user using hir\her role id. and in aspx file i have this code to fill asp menu control

int RoleNo = Convert.ToInt16(Session["RoleId"]); objLogin.Role_Id = RoleNo; DataTable dt = new DataTable(); dt = objLogin.MenuMaking(); GridView1.DataSource = dt; GridView1.DataBind(); foreach (DataRow dr in dt.Rows) { MenuItem objMenuItem = new MenuItem(); objMenuItem.Text = dr["Path_Detail"].ToString(); objMenuItem.NavigateUrl = dr["Path_Url"].ToString(); MenuBar.Items.Add(objMenuItem); }

这个工作正常，但我想在父菜单下显示子菜单。我怎么能实现这个？

推荐答案

有子菜单你只需将menuItems添加到menuItems ChildItems。 to have submenus you just add menuItems to a menuItems ChildItems. // Retrieve the root menu item from the Items // collection of the Menu control using the indexer. MenuItem homeMenuItem = NavigationMenu.Items[0]; // Create the submenu item. MenuItem newSubMenuItem = new MenuItem("New Category"); // Add the submenu item to the ChildItems // collection of the root menu item. homeMenuItem.ChildItems.Add(newSubMenuItem);
