The following is my menu item data table in design mode:

sql database

The following is the script of my table:

CREATE TABLE [dbo].[tbl_Menu](
[Menu_ID] [int] IDENTITY(1,1) NOT NULL,
[Menu_ParentID] [int] NULL,
[Menu_Name] [varchar](50) NULL,
[Menu_Page_URL] [varchar](500) NULL,
CONSTRAINT [PK_tbl_Menu] PRIMARY KEY CLUSTERED
(
[Menu_ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

Now the data in my tbl_Menu table:

tbl_menu table

Here in this application I am using a Master Pager to provide a consistent look in the entire application. So I wrote code to generate a menu item from the database in MasterPage.master.cs.

The following is my MasterPage.Master:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs" Inherits="MenuFromDB.MasterPage" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<link href="StyleSheetMenu.css" rel="stylesheet" />
<link href="StyleSheet.css" rel="stylesheet" />
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<table cellpadding="1" cellspacing="1" width="880px" align="center" class="BlueBorder"
style="background: White;">
<tr>
<td style="height: 100px; background-color: skyblue; padding-left: 10px;">
<span style="font-size: 20pt; font-weight: bold; color: blue;">Data Base Driven Menu Item In ASP.NET C#</span>
</td>
</tr>
<tr>
<td style="background-color: orange; padding-left: 1px;">
<asp:Menu ID="MenuFromDB" runat="server" Orientation="Horizontal">
<levelmenuitemstyles>
<asp:menuitemstyle cssclass="Parent_Menu" />
<asp:menuitemstyle cssclass="level_menu" />
</levelmenuitemstyles>
<staticselectedstyle cssclass="selected" />
</asp:Menu>
</td>
</tr>
<tr>
<td style="padding-top: 40px; padding-bottom: 80px; padding-left: 10px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>

Now the MasterPage.Master.cs is:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
namespace MenuFromDB
{
public partial class MasterPage : System.Web.UI.MasterPage
{
SqlDataAdapter da;
DataSet ds = new DataSet();
DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
dt = GetMenuDataFromDB(0);
PopulateMenu(dt, 0, null);
}
}
public DataTable GetMenuDataFromDB(int MenuParentID)
{
SqlConnection con = new SqlConnection();
ds = new DataSet();
con.ConnectionString = @"Data Source=MyPC\SqlServer2k8; Initial Catalog=Test; Integrated Security=true;";
SqlCommand cmd = new SqlCommand("SELECT * FROM tbl_Menu WHERE Menu_ParentID='" + MenuParentID + "'", con);
da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
return ds.Tables[0];
}
private void PopulateMenu(DataTable dt, int Menu_Parent_ID, MenuItem Parent_MenuItem)
{
string currentPage = Path.GetFileName(Request.Url.AbsolutePath);
foreach (DataRow row in dt.Rows)
{
MenuItem menuItem = new MenuItem
{
Value = row["Menu_Id"].ToString(),
Text = row["Menu_Name"].ToString(),
NavigateUrl = row["Menu_Page_URL"].ToString(),
Selected = row["Menu_Page_URL"].ToString().EndsWith(currentPage, StringComparison.CurrentCultureIgnoreCase)
};
if (Menu_Parent_ID == 0)
{
MenuFromDB.Items.Add(menuItem);
DataTable dtChildMenu = new DataTable();
dtChildMenu = this.GetMenuDataFromDB(int.Parse(menuItem.Value));
PopulateMenu(dtChildMenu, int.Parse(menuItem.Value), menuItem);
}
else
{
Parent_MenuItem.ChildItems.Add(menuItem);
}
}
}
}
}
