Display records in ASP.NET using MVC


Introduction : I developed a simple application to display person records in ASP.NET using MVC tools. This application for beginners to help them understand what MVC tools is and the benefits of ASP.NET MVC.

ASP.NET MVC gives you a powerful, patterns-based way to build dynamic websites that enables a clean separation of concerns and that gives you full control over markup for enjoyable, agile development. ASP.NET MVC includes many features that enable fast, Test-driven development-friendly development for creating sophisticated applications that use the latest web standards. ASP.NET MVC is a part of the ASP.NET Web application framework. It is one of the two different programming models you can use to create ASP.NET Web applications, the other being ASP.NET Web Forms.

  • Model: The model contains the core information for an application. This includes the data and validation rules as well as data access and aggregation logic.
  • View: The view encapsulates the presentation of the application, and in ASP.NET this is typically the HTML markup.
  • Controller: The controller contains the control-flow logic. It interacts with the Model and Views to control the flow of information and execution of the application.

Step 1 : Open Visual Studio 2010.

  • Go to file -> New->Projects.

        public string  name { get; set; }

 using MvcCustomer.Models;
 namespace MvcCustomer.Controllers
{
    public class CustomerDiaplayController : Controller
    {
        //
        // GET: /CustomerDiaplay/
        public ActionResult Index()
        {
            Person pr = new Person();
            pr.id = 1000;
            pr.name = "manish singh";
            pr.salary = 20000;
            return View(pr);
        }
    }
}

Step 4 :

  • Right click of Index Method -> Add View.

  • View name same as "Index".

  • Create a Strong type View.

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MvcCustomer.Models.Person>" %>
 <!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">

    person name is <% = Model.name %><br />
    persone salary is <% = Model.salary %>
    </div>
