如何从数据库创建动态Aspxmenu

Question

**我在C＃上工作。**我想开发包含菜单的asp.net应用程序，但是应该从数据库生成菜单项。我的意思是管理员可以通过仅在数据库上工作来更改菜单项，无需如何更改前端。

**

For example: Web page contains Menu as 
   1. Home
   2. About Us
   3. Contact Us

**

  So if Administrator wants can change  About Us menu to Our Clients menu, so administrator only need to modify in database don't touch front end any how.

  Any small help also appreciated.
  Thanks in advance.

Bellow是我的SQL脚本：

Menu_Type=1=Form
Menu_Type=2=Report

Tree_Level=1=MainMenuItem.
Tree_Level=2=SubMenuItem.
Tree_Level=3=Sub-SubMenuItem.

在服务器端，AspxMenu如何与XML文件绑定。实际上我需要1）使用Linq创建XML文件。 2）然后我需要将此文件与AspxMenu绑定。

使用Linq我想创建像下面这样的.xml文件：

 XElement xml = new XElement("MyMenu",
                  from c in db.Security_Module_Menus
                  where (c.ParentID == 0)
                  orderby c.Menu_ID
                  select new XElement("Item",
                            new XAttribute("Text", c.Menu_Name), new XAttribute("NavigateUrl",c.Target_URL)


                            )
                  );
**Fill AspxMenu like bellow:**
            XmlDataSource1.DataFile = @"C:\contacts.xml";
        XmlDataSource1.XPath = "MyMenu/Item";

我需要帮助来创建XML文件。帮助我根据下面的标准创建Xml文件

    Menu_Type=1=Form
    Menu_Type=2=Report

    ParentID=0=MainMenuItem

    Tree_Level=1=MainMenuItem.
    Tree_Level=2=SubMenuItem.
    Tree_Level=3=Sub-SubMenuItem.
