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：

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.

根据设计，ASPxMenu仅支持通过其DataSourceID和DataSource属性绑定到分层数据源（实现IHierarchicalDataSource接口的数据源 - 例如XmlDataSource，SiteMapDataSource）。

如果需要将ASPxMenu控件绑定到数据表，则需要一些额外的编码。

我们发布了一个教程，说明如何根据数据库信息动态创建ASPxMenu控件： http://www.devexpress.com/Support/Center/e/E49.aspx

本教程是附加到以下问题的项目的简化版本： http://www.devexpress.com/Support/Center/p/DQ42250.aspx
