Data fetching using Request object in MVC| MVC Tutorials | data fetching from view to controller

fetch data from view to controller using request

In this article I will explain how to fetch data from controls which are on View to Controller using Request. In my last article I explain the same example using FormCollection. Request objects work with both GET and POST Method.

Example of Request object

In this example I have created the Home Controller and in this I have created index view.

In this view I have created the following form in which I am taking first name and last name from the user. For each control I have set the property name. This property I will use in form collection to fetch the data.

Code of Index.cshtml

		
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <form method="get" action="Welcome\Index">
        <table>
            <tr>
                <td>Enter First Name</td>
                <td><input type="text" id="fname_id" name="fname_name" /></td>
            </tr>
             <tr>
                <td>Enter Last Name</td>
                <td><input type="text" id="lname_id" name="lname_name" /></td>
            </tr>
             <tr>
                <td></td>
                <td><input type="submit"  /></td>
            </tr>
        </table>
    </form>
</body>
</html>

In action I have set the welcome controller and index view. So I have created welcome controller and create index view.

I have fetched the data using Request and pass name property (which we set for the controls) as a key

Code of Home Controller

		
		using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication1.Controllers
{
    public class WelcomeController : Controller
    {
        

        public ActionResult Index()
        {
            string fname = Request["fname_name"];
            string lname = Request["lname_name"];
            Response.Write("Your Full name is= " + fname + " " + lname);

            return View();
        }

    }
}

Now execute this code

Output when method set as Get

Output when method set as Post

As you can see that we can fetch data in controller. So after fetching data we can also store in the database.
