TempData lost on page reload

I use TempData to store login user role but after the user logs in and presses F5 to reload the page, I run into an error stating that Object reference not set to an instance of an object

I use TempData because my page needs redirection. The user fills in the login form before submitting it, I don't know how to retrieve the posted data since I need to redirect the user to admin page in case his role is administrator or just standard page in case his is normal user.

    private bool IsAdmin(string username)
    {
        return (Roles.GetRolesForUser(username).ToList().Contains("administrator"));
    }

    public ActionResult AdminLayout() 
    {            
        if(IsAdmin(TempData["LoginUsername"].ToString())) //Error TempDate on Reload
        {
             return View();
        } 
        else
        {
             return Index();
        }
    }

Why don't you store it in a session variable? As the name suggests, TempData is only temporary and session variables will hold the data for longer.
