Fetch values from
View in 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.
For Example:-
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.
@{
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
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(FormCollection data)
{
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.
For any
query you can send me mail at info@techaltum.com
