问题描述

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)

通过以上查询，我使用hir \her角色ID确认指定用户的菜单。

和aspx文件中我有这个代码来填充asp菜单c ontrol

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？

this is working fine but i want to show child menu too under it parent menu. How can i acheive this??

推荐答案

// 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);
