How to use more than 1 model per page using asp.net mvc 5?
I want to use 2 models. The first is on the page Index.cshtml
and the second is on the page_Layout.cshtml
In the controller that contains the action public ActionResult Index(){...}
, I declare some values and return them to View (). Like this:
public ActionResult Index()
{
HomePageViewModel model = new HomePageViewModel();
// do something...
return View(model);
}
And in MyProjectName.Models
I am writing some classes to check the account and put it on the page _Layout.cshtml
. Like this:
On the page _Layout.cshtml
:
@using MyProjectName.Models
@model MyProjectName.Models.LoginModel
@if (Model.LoginAccount != null)
{
foreach(Account acc in Model.LoginAccount)
{
@Html.ActionLink(@acc.Email, "SomeAction", "SomeController", null, new { id = "loginEmail" })
@Html.ActionLink("Logout", "SomeAction", "SomeController", null, new { id = "logout" })
}
}
The code on the page _Layout.cshtml
doesn't work. He said that: I returned a model ( HomePageViewModel model
), but some of the values I want to display refer toMyProjectName.Models.LoginModel
Basic requirement: the first model is used to display content on the page Index.cshtml
, and the second model is used to validate user login (on the page _Layout.cshtml
).
Can you tell me how to do this? Thank!
In your layout, use Html.Action()
or Html.RenderAction()
to call a method ChildActionOnly
that returns a partial view forLoginModel
[ChildActionOnly]
public ActionResult Login()
{
LoginModel model = // initialize the model you want to display in the Layout
return PartialView(model);
}
and create a partial view showing links then in layout
@ { Html.RenderAction("Login", "yourControllerName") }

The best approach would be to use Partial Views and ViewBag.
in your controller, you would do something similar to this:
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Accounts = new AccountsViewModel();
ViewBag.HomePage = new HomePageViewModel();
return View();
}
}
From here you can pass your model from ViewBag to partial view
@{
AccountViewModel Accounts = (AccountViewModel)ViewBag.Accounts;
}
@Html.Partial("_accountPartial", Accounts)
