Introduction: We have know that the MVC is three separated words that are models,views,controllers. Models provide the business logic of your application. Views provide the Graphical user interface of your application. Controllers is handle all models and views requested. This is a simple application that provides help on how to add more then one area of your application. ASP.NET MVC makes use of interfaces, abstract classes, virtual methods. If you are not well-versed with these object-oriented concepts then the framework might not be very friendly for you.

The MVC pattern separates the model logic of an application from its presentation logic and business logic. In ASP.NET MVC logical separation is also implemented physically in the project structure where controllers and views are kept in folders that use naming conventions to define relationship. This structure supports the needs of most Web applications. Areas provide a way to separate a large MVC Web application into smaller functional groupings. An area is effectively an MVC structure inside an application. An application could contain several MVC structures.

Step1: Open Visual Studio 2010.

Go to file -> New->Projects

Name it as "manish application"

Right click on "Solution Explorer"->add->area
Area name is "sandeep"

Step4: Add a controller in the manish area folder..

Click on manish area folder
Right Click on controllers->add->controller
The controller name is "manish"

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Ajax;
namespace ManishApplication1.Areas.manish.Controllers
{
    public class manishController : Controller
    {
        //
        // GET: /manish/manish/
        public ActionResult ShowNewData()
        {
            return View();
        }
        public ActionResult ShowCombination()
        {
            return View();
        }
    }

    {
        //
        // GET: /sandeep/sandeep/
        public ActionResult AddData()
        {
            return View();
        }
        public ActionResult EditData()
