Hi Friend,Today we will learn "How to implement form based authentication concepts in ASP.NET MVC Application". This concepts is basically used for authenticating the user credentials using Forms.In Previous post , i have already implemented two authentication concepts in asp.net application .which are as given below:-
There are some steps to implement this concepts in asp.net mvc application as given below:-
Step 1 :- First open your visual studio --> File -->Project --> Select ASP.NET MVC 3 OR MVC 4 Application --> write your project name --> press OK as shown below:-
Step 2 :- Now select Empty template -->Choose ASPX view engine as shown in below image.- How to implement form based authentication in asp.net application

There are some steps to implement this concepts in asp.net mvc application as given below:-
Step 1 :- First open your visual studio --> File -->Project --> Select ASP.NET MVC 3 OR MVC 4 Application --> write your project name --> press OK as shown below:-
How to pass data from controller to view in asp.net mvc application.
Step 5 :-
- Now open login_form.asp page (view engine) --> Design text boxes and button controls using coding (you can add Html controls from toolbox) as given below:-
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<!DOCTYPE html>
<html>
<head runat="server">
<meta name="viewport" content="width=device-width" />
<title>login_form</title>
</head>
<body>
<div>
<form action="Authenticate_User" method ="post">
<span class="auto-style1"><strong> Simple Form Based Authentication in ASP.NET MVC Application</strong></span><br />
<br />
Enter User Name <input id="txt_id" name ="txt_id" type="text" /> <br />
Enter Password <input id="txt_Pass" name="txt_pass" type="password" /><br />
<input id="Submit1" type="submit" value="Login" />
</form>
</div>
</body>
</html>
- Now go Design mode --> You will see following login layout as shown below:-
1.) <form action="Authenticate_User" method ="post"> ,this Action (Authenticate_User) will be invoked when any user fill the login credentials and press login button.
2.) This action = Authenticate_User will call the controller class ActionResult method = Authenticate_User .
3.) This action (Authenticate_User ) will execute and check the user credentials from controller class .if entered user name and password are correct then it returns home_page otherwise returns same page.
4.) Method = "post" is used to retrieve the data from the page.you can use Get Method also.But it less secure and slower than post. you can see, Facebook is also used Post Method .
Step 6 :- Now Write the codes in Authentication_Controller.cs file as given below:-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
namespace SIMPLE_ASP.NET_MVC__AUTHENTICATION.Controllers
{
public class Authentication_Controller : Controller
{
//
// GET: /Authentication_/
public ActionResult login_form()
{
return View("login_form");
}
// Add [Authorize] Attribute to Authenticate the below codes
[Authorize]
public ActionResult home_page()
{
return View("home_page");
}
public ActionResult Authenticate_User()
{
//here we will check the users for forms authetication
//first check whether username and passwordis correct or not
if ((Request.Form["txt_id"] == "ram") && (Request.Form["txt_pass"] == "ram123"))
{
FormsAuthentication.SetAuthCookie(Request.Form["txt_id"], true);
return View("home_page");
}
else if ((Request.Form["txt_id"] == "neha") && (Request.Form["txt_pass"] == "neha123"))
{
FormsAuthentication.SetAuthCookie(Request.Form["txt_id"], true);
return View("home_page");
}
else if ((Request.Form["txt_id"] == "sujeet") && (Request.Form["txt_pass"] == "sujeet123"))
{
FormsAuthentication.SetAuthCookie(Request.Form["txt_id"], true);
return View("home_page");
}
else
{
//if entered data(username and passowrd) is incorrect,then return back to login_form
return View("login_form");
}
}
}
}
Descriptions:-1.) First include namespace using System.Web.Security; This is used in form authentication.
2.) If any user want to login then it first call the ActionResult = Authenticate_User.
3.) Here I have used a [Authorize] attribute.Which is used form validation purpose.Means nobody (anonymous user) can access the data by passing the Urls in Browser directly.
4.) Here, i have validated the user name and password using RequestForm methods in controller class as shown in above codes.
5.) Here i have set cookie also.
6.) In above codes, our application returns a view "home_page". I will create it in Step 7
Step 7 :- Now Right click on Authenticate_User action --> Add a view (home_page) as shown below:-
[Authorize]
public ActionResult home_page()
{
return View("home_page");
}
Step 10:- Now open Web.Config file from Solution Explorer window --> Write the following codes as shown below:-
<forms loginUrl="~/Authentication_/login_form" timeout="2880" />
Means
<forms loginUrl="~/Controller-name/view-name" timeout="2880" />
Step 11:- Now Run the application (press F5) --> You will see following error as shown below:-
localhost:1509/Controller-name/View-name
OR
localhost:1509/Authentication_/login_form
