Menu
I am new to MVC, I looked through similar posts on stack, but they did'nt seem to help my problem. I have two roles Admin and User. When a person logs in, I want the layout to change based on whether the person had Admin privileges or User Privileges.
My Admin Layout is _Layout.cshtml
My User Layout is _LayoutUser.cshtml
Is there something in my Login Controller that I can put which will change the layout based on the role of the User? The role of the user is specified in the Login table.
id LoginStudentNumber LoginPassword Role
1 123456 123456 Admin
2 234567 234567 Admin
3 345678 345678 User
4 456789 456789 User
Login Controller:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using RMS.DAL;
using RMS.Models;
namespace RMS.Controllers
{
public class LoginController : Controller
{
RMSContext db = new RMSContext();
[AllowAnonymous]
public ActionResult Login(string returnUrl)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
public ActionResult Login(Login model, int? LoginStudentNumber, string LoginPassword)
{
//RMS.Models.Login user = db.Logins.Find(LoginID);
RMS.Models.Login user = db.Logins.FirstOrDefault(l => l.LoginStudentNumber == model.LoginStudentNumber);
if (user == null)
{
ViewBag.InvalidID = "Invalid User Id";
return View(model);
}
if ((user.LoginPassword.Equals(LoginPassword)) && (user.Role.Equals("Admin")))
{
return RedirectToAction("Index", "Home");
}
if ((user.LoginPassword.Equals(LoginPassword)) && (user.Role.Equals("User")))
{
return RedirectToAction("IndexUser", "Home");
}
ViewBag.InvalidPassword = "Invalid Password";
return View(model);
}
}
}

You just need to modify the /Views/_ViewStart.cshtml file.
@{
if (this.User.IsInRole("Admin") || !this.User.Identity.IsAuthenticated) {
Layout = "~/Views/Shared/_Layout.cshtml";
} else {
Layout = "~/Views/Shared/_LayoutUser.cshtml";
}
}
You didn't mention what should happen if no user is logged in, so I added the check and just sent them to the
_Layout.cshtmlview. You should change the logic as needed for your application.

You need to first work in global.asax file add the method Application_PostAuthenticateRequest . Then get your roles from database ex:
roles = spRepository.GetUserRolByUsername(username)
then add this roles to HttpContext ex:
HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(
new System.Security.Principal.GenericIdentity(username, "Forms"), roles.Split(';'));
Finally you can access role from your layout page:
@if (HttpContext.Current.User.IsInRole("Administrator"))
{
Html.RenderPartial("AdminMenu");
}
