• Design & Develop ASP.NET MVC Controller.
How to create a controller:-
Go to solution explorer Right-click on “Controller” Folder >> Click on Add >> click on
“Controller” as follow.
HomeController.cs
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace controllerpro.Controllers
{
public class HomeController : Controller
{
// GET: Home
public string name()
{
return "Hiiiiiiiiii RCP";
}
public string name1()
{
return "RCPIMRD";
}
}

}
• Design & Develop Model Templates using Metadata for data values.
• Steps to create ASP.NET MVC 4 Application using Visual Studio.
• Open => Visual Studio and go to File >> New >> Click on Project as follow.
• Select “ASP.NET Web Application” and provide a meaningful name like
“WebApplication25” and Click on “Ok” button.
• Select the “Empty” template and check the “MVC” checkbox from “New Web
Application” window as follow.
Below file is HomeController.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using WebApplication25.Models; //this file as to be included
namespace WebApplication25.Controllers
{
{
public ActionResult Index()
{
var data = GetEmployee();
return View(data);
}
private Employee GetEmployee()
{
return new Employee()
{
id = 1,
Address = "India",
Name = "RCP",
};

}
}
}
• After coding above code, now to add Model class.
• Look for the Model is Solution Explorer.
• Right click on Model Click on Add Select Class give name to the class
Employee.cs
Do the following code in Employee.cs file
using System;
using System.Linq;
using System.Web;
namespace WebApplication25.Models
{
public class Employee
{
public int id { get; set; }
public string Name { get; set; }
public string Address { get; set; }
}
}
Right click in the Index() and add Index.cshtml
Index.cshtml

• Make sure we add created model in the Index.cshtml
• First line @model contains the Applicationname. Models.ClassName
• In this example WebApplication25 is Application name and Employee is
ClassName
@model WebApplication25.Models.Employee
@{
ViewBag.Title = "Index";
}
<body>
<center>
<h1>Model Templates using Metadata for data values. </h1>
<table style="border:5px solid black; ">
<tr>
<th style="border:5px solid red;">ID</th>
<th style="border:5px solid red;">@Model.id</th>
</tr>
<tr>
<th style="border:5px solid red;">Name</th>
<th style="border:5px solid red;">@Model.Name</th>
</tr>
<tr>
<th style="border:5px solid red;">Address</th>
<th style="border:5px solid red;">@Model.Address</th>
</tr>
</table>
</center>
</body>
• Demonstrate ASP.NET MVC for Model Validation.
Open Microsoft Visual studio Click on file NewProject Dialog Box will appear,
Select Asp.net Web application (.net Framework) click ok next dialog box will
appear select MVC and click ok. New Web application will be open
You can rename the controller name by :- Right click on HomeController and select
rename option and you can rename it. In this example StudentController.cs name is
given
Following is StudentController.cs file
using System;
using System.Linq;
using System.Web;
{
public class StudentsController : Controller
{

{
return View();
}
public ActionResult About()
{
ViewBag.Message = "Your application description page.";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
}
Open Index.cshtml file by right clicking on view() in to ActionResult Index() and do
the following code
Index.cshtml file
@model WebApplication7.Models.Student
@{
}
<h2>Validation Form</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Name, htmlAttributes: new { @class =
"control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Name, new { htmlAttributes = new {
@class = "form-control" } })
@Html.ValidationMessageFor(model => model.Name, "", new { @class =
"text-danger" })
</div>
</div>
@Html.LabelFor(model => model.Email, htmlAttributes: new { @class =

@Html.EditorFor(model => model.Email, new { htmlAttributes = new {
@Html.ValidationMessageFor(model => model.Email, "", new { @class =
"text-danger" })
</div>
</div>
@Html.LabelFor(model => model.Contact, htmlAttributes: new { @class =
@Html.EditorFor(model => model.Contact, new { htmlAttributes = new {
@Html.ValidationMessageFor(model => model.Contact, "", new { @class
= "text-danger" })
</div>
</div>
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
Right click on Models in Solution Explorer click on Add click on class Rename the
model Class As Student.cs and do the following code
Student.cs file
using System;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
{
public class Student
{
public int ID { get; set; }
// -- Validating Student Name
[Required(ErrorMessage = "Name is required")]
[MaxLength(12)]

// -- Validating Email Address
[Required(ErrorMessage = "Email is required")]
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
// -- Validating Contact Number
[Required(ErrorMessage = "Contact is required")]
[DataType(DataType.PhoneNumber)]
[RegularExpression(@"^(?([0-9]{3}))?[-. ]?([0-9]{3})[-. ]?([0- 9]{4})$",
ErrorMessage = "Not a valid Phone number")]
public string Contact { get; set; }
}
}
4) Design & develop to demonstrate working with razor engine.
appear select MVC and click ok. New Web application will be open
HomeController.cs file
using System;
using System.Linq;
using System.Web;
using WebApplication28.Models;//This Line as to be included
{
{
{
return View();
}
}
}
Now add model class right click on model in solution explorer click on add
buttonthen select class and name it as Student_Model.cs
using System;
using System.Linq;
using System.Web;
{
public class Student_Model
{
public int student_id { get; set; }
public string studnet_name { get; set; }
public string student_address { get; set; }

public string student_context { get; set; }
public string student_city { get; set; }
public string male { get; set; }
public string Female { get; set; }
}
}
Next go to HomeController and right click on View() in Index().Then do the coding
in Index.cshtml file
@model WebApplication28.Models.Student_Model //Include this line after adding
//Student_Model.cs
@{
}
<h1>Student Information</h1>
<div class="row">
<label>Student Name</label>
@Html.TextBoxFor(m => m.studnet_name, new { @class = "form-control" })
<label>Student Address</label>
@Html.TextAreaFor(m => m.student_address, new { @class = "form-control" })
<label>Student Contact</label>
@Html.TextBoxFor(m => m.student_context, new { @class = "form-control" })
<label>Student City</label>
@Html.DropDownListFor(m=>m.student_city , new List<SelectListItem> {
new SelectListItem { Text="--Select City--",Value="0"},
new SelectListItem { Text="Pune",Value="1"},
new SelectListItem { Text="Mumbai",Value="2"},
new SelectListItem { Text="Indore",Value="3"},
new SelectListItem { Text="Dhule",Value="4"}
} ,new {@class="form-control" })
<label>Male</label>
@Html.RadioButtonFor(m => m.male, "Male", new { @class = "form-control" })
<label>Female</label>
@Html.RadioButtonFor(m => m.male, "Female", new { @class = "form-control"
})

appear select Empty and click on web API
Adding a Model
• Add the following code in model class: Product.cs
using System;
using System.Linq;
using System.Web;
{
public class Product
{
public int Id { get; set; }
public string Category { get; set; }
public decimal Price { get; set; }
}
}
Adding a Controller

In Solution Explorer, right-click the Controllers folder. Select Add and then select
Controller.
In the Add Scaffold dialog, select Web API Controller - Empty. Click Add.
In the Add Controller dialog, name the controller "ProductsController". Click Add.
The scaffolding creates a file named ProductsController.cs in the Controllers folder.

If this file is not open already, double-click the file to open it. Replace the code in this file
with the following.
using System;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using WebApplication21.Models;
{
public class ProductsController : ApiController
{
Product[] products = new Product[]
{
new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 },
new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M },
new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M }
};
public IEnumerable<Product> GetAllProducts()
{
return products;
}
public IHttpActionResult GetProduct(int id)
{
var product = products.FirstOrDefault((p) => p.Id == id);
if (product == null)
{
return NotFound();
}
return Ok(product);
}
}
}
