Hello Ranganath,

Here is an example of connecting to the database (in this case, Northwind) and creating dynamic RadMenuItems to add to a RadMenu. Keep in mind that this is just a simple example and you would want to use your own data access classes to retrieve relevant data from your tables.

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="DynamicRadMenu.aspx.cs" Inherits="DynamicRadMenu" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <telerik:RadScriptManager ID="RadScriptManager1" runat="server" />       
        
                    <telerik:RadMenu ID="RadMenu1" runat="server" />         
        
                </form> 
        
            </body> 
        
            </html>

    
            using System; 
        
            using System.Data; 
        
            using System.Data.SqlClient; 
        
            public partial class DynamicRadMenu : System.Web.UI.Page 
        
            { 
        
                protected void Page_Load(object sender, EventArgs e) 
        
                { 
        
                    var dataTable = this.GetData(); 
        
                    foreach (DataRow row in dataTable.Rows) 
        
                    { 
        
                        var companyName = Convert.ToString(row["CompanyName"]); 
        
                        var navigateUrl = String.Format("http://www.someurl.com/customers?id={0}", Convert.ToString(row["CustomerID"])); 
        
                        var menuItem = new Telerik.Web.UI.RadMenuItem(companyName, navigateUrl); 
        
                        RadMenu1.Items.Add(menuItem); 
        
                    } 
        
                } 
        
                private DataTable GetData() 
        
                { 
        
                    var data = new DataTable(); 
        
                    using (SqlConnection con = new SqlConnection("Data Source=.\\SQLSERVER;Initial Catalog=Northwind;User ID=sa;Password=*******")) 
        
                    { 
        
                        var sql = "SELECT TOP 5 [CompanyName], [CustomerID] FROM [Customers];"; 
        
                        using (SqlCommand cmd = new SqlCommand(sql, con)) 
        
                        { 
        
                            cmd.CommandType = CommandType.Text; 
        
                            SqlDataAdapter adapter = new SqlDataAdapter(cmd); 
        
                            try 
        
                            { 
        
                                // Retrieve the records 
        
                                adapter.Fill(data); 
        
                            } 
        
                            catch (SqlException e) { } 
        
                        } 
        
                    }  
        
                    return data; 
        
                } 
        
            }

I hope this example helps.

Sincerely,
Kevin Babcock
