Question

I would like to set up a menu navigation on the left side of my page which is only shown up after the user logs in.

I don’t know how can I achieve this with MVC4 WebSecurity class and Razor in my index.cshtml file.

Answer 1

try using 2 Layout:

_Layout.cshtml for non login user and

_memberLayout.cshtml for login user.
put your member menu in _memberLayout.

/Home/Index controller:

    public ActionResult Index()
    {
        if (User.Identity.IsAuthenticated)
        {
            return RedirectToAction("Index", "Member");
        }

        return View();
    }

/Member/Index controller:

    [Authorize]
    public ActionResult Index()
    {
        return View();
    }

Index.cshtml in Member folder:

@{
    ViewBag.Title = "Member Area";
    Layout = "~/Views/Shared/_memberLayout.cshtml";
}

<div>
         ... your member html code
</div>
