If the logged-in user is in Admin role, then we want to display Manage Roles navigation menu item. If the logged-in user IS NOT in Admin role, then Manage Roles navigation menu item should not be displayed.

Show or hide navigation menu based on logged-in user role

Navigation menu is in the laylout view (_Layout.cshtml).
Inject SignInManager service into the layout view using @inject directive
Use the SignInManager service, IsSignedIn() method and IsInRole() method to check if the user is signed in and if the user is in the Admin role

@using Microsoft.AspNetCore.Identity
@inject SignInManager[ApplicationUser] SignInManager

[ul class="navbar-nav"] [li class="nav-item"] [a class="nav-link" asp-controller="home" asp-action="index"]List[/a] [/li] [li class="nav-item"] [a class="nav-link" asp-controller="home" asp-action="create"]Create[/a] [/li] @if (SignInManager.IsSignedIn(User) && User.IsInRole("Admin")) { [li class="nav-item"] [a class="nav-link" asp-controller="Administration" asp-action="ListRoles"] Manage Roles [/a] [/li] }
[/ul]

What if the user types the URL in address bar

The URL associated with Manage Roles navigation menu item is /Administration/ListRoles. What if the user types this URL directly in the address bar.

The Authorize attribute on the AdministrationController protects from the unauthorised access. If the logged-in user is not in Admin role, asp.net core automatically redirects the user to /Account/AccessDenied.

[Authorize(Roles = "Admin")]
public class AdministrationController : Controller
{ // Code
}

AccessDenied action in AccountController

public class AccountController : Controller
{ [HttpGet] [AllowAnonymous] public IActionResult AccessDenied() { return View(); } // Other actions
}

AccessDenied View

[div class="text-center"] [h1 class="text-danger"]Access Denied[/h1] [h6 class="text-danger"]You do not have persmission to view this resource[/h6] [img src="~/images/noaccess.png" style="height:300px; width:300px" /]
[/div]
