LogOn Partial View

I want if user has not logged in then below View should open.

@Html.Partial("_LogOnPartial")

In ViewStart below is the Code . I want if User is not logged in then Login Partial Modal Popup should open.

@{
Layout = "~/Views/Shared/_Layout.cshtml";
}

In Web.Config i have written below code

******************************************************************

public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}

*********************************************************************************************************

public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
}

Thanks

In your account controller there must be two views one Login get and one post.

[HttpGet]
public ActionResult Login(string ReturnUrl)
{
ViewBag.ReturnUrl = ReturnUrl;
return View();
}
[HttpPost]
public ActionResult Login(string UserName, string Password, bool RememberMe, string
ReturnUrl)
{
FormsAuthentication.SetAuthCookie(UserName, RememberMe);
return Redirect(ReturnUrl);
return View("Login");
}

step 2. Design the view as

@{
ViewBag.Title = "Login";
}
Login
"/Home/Login" method="post">
User Name:@Html.TextBox("UserName")
Password :@Html.Password("Password")
Remember Me:@Html.CheckBox("RememberMe")
@Html.Hidden("ReturnUrl", new { @value = ViewBag.ReturnUrl})
"submit">Login

Now mark the controller like Home and other controllers with [Authorize] attribute. if you want controller based security, otherwise mark the method which you think requires users authentication as Authorize.

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