Using Models in MVC

What is Models in MVC.

You might see lot of definitions for Models in MVC. This will be interesting.

Model is nothing but a creation of property class for the member functions. We can directly add class and define all the entities in it. Else, we can Add Entity models directly from the Database using Entity framework. It will just bring your database structure to the .edmx file.so it’s also called as mirror of database design.

Ø  Open new project and Create MVC Application,

Ø  Right click on the Models and create new class as below.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace ModelsExample.Models

{

    public class Employee

    {

        public int EmployeeID { get; set; }

        public string Name { get; set; }

        public string Gender { get; set; }

        public string City { get; set; }

    }

}

Ø  On controller’s folder Right Click and create new controller by maintaining Controller at the end. Here my controller is named as ‘EmployeeController’

Ø  Add model reference in the namespace section of controller, this will be helpful to access the models in controller.

Below is my controller code.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using ModelsExample.Models;

namespace ModelsExample.Controllers

{

    public class EmployeeController : Controller

    {  

        public ActionResult Details()

        {

            Employee employee = new Employee()

            {

                EmployeeID=101,

                Name="Rajamouli",

                City="Hyderbad",

                Gender="Male"

            };

            return View(employee);

        }

    }

}

Ø  Right click on Controller action and create the view it. Maintain the same name as it generated the Action Result name.

To access the models in the View,

·         we need to create the Strongly typed View.

·         We need to return Model in the view from the action result

         View code.

@model ModelsExample.Models.Employee

@{

    ViewBag.Title = "Employee Details";

}

<h2> Employee Details</h2>

<span>Employee City : </span> @Model.City <br />

<span>Employee Name :</span>@Model.Name <br />

<span>Employee Id   :</span>@Model.EmployeeID<br /> 

<span>Gender : </span>@Model.Gender

Ø  Output will be Like:
