ASP.NET Model View Controller

Introduction

The MVC (Model-View-Controller) architecture is a way of decomposing an application into three parts: the model, the view and the controller. It was originally applied in the graphical user interaction model of input, processing and output. A model represents an application's data and contains the logic for accessing and manipulating that data. Any data that is part of the persistent state of the application should reside in the model objects. The view is responsible for rendering the state of the model. The presentation semantics are encapsulated within the view, therefore model data can be adapted for several different kinds of clients. The controller is responsible for intercepting and translating user input into actions to be performed by the model. The controller is responsible for selecting the next view based on user input and the outcome of model operations.

Example

• Model Code

        public class model
        {
            public string name { get; set; }
            public int id { get; set; }
        }

• Controller code:

        model ms = new  model();
        public ActionResult Index11()
        {
            ViewData["Message"] = "Welcome to ASP.NET MVC!";
            ms.name = "Hello Users";
            ms.id = 10000;
            return View();
         }

• View code

         <p>
         <%=Html.TextBox(Model.name) %>
         </p>
         <p>
         <%=Html.TextBox(Model.id.ToString()) %>
         </p>
