ASP.NET return multiple list to view

Question

I am using ASP.NET MVC Entity Framework and I am trying to return two list to one view.

So far I am able to return one list:

public ActionResult Index()
{
    return View(db.Data.ToList().Where(model => model.hidden == false).Where(model => model.collection == "Singles"));
}

I also need to return:

db.Data.ToList().Where(model => model.hidden == false).Where(model => model.collection == "Towns")

Just create a ViewModel that contains both lists and pass it to the View. — Red, Sep 07 '16 at 18:51

Create a view model with 2 properties.

Assuming db.Data returns a collection of type Data

public clas ListViewModel
{
  public List<Data> SinglesData { set;get;}
  public List<Data> TownsData { set;get;}
}

Now use this

public ActionResult Index()
{
  var vm=new ListViewModel();
  vm.SinglesData = db.Data
                     .Where(a=> a.hidden == false && a.collection == "Singles").ToList();
  vm.TownsData = db.Data
                   .Where(b=> b.hidden == false && b.collection == "Towns").ToList();
  return View(vm);
}

Now make sure your view is strongly typed to the new view model

@model ListViewModel
<h2>Singles Data </h1>
@foreach(var item in Model.SinglesData)
{
  <p>@item.SomeProperty</p>
}
<h2>Towns Data </h1>
@foreach(var item in Model.TownsData)
{
  <p>@item.SomeProperty</p>
}

I get an error saying `Data could not be found` in my new class – user979331 Sep 07 '16 at 19:23
This is what db is `private Homefront db = new Homefront();` – user979331 Sep 07 '16 at 19:24
What is the type of `db.Data.ToList()` ? or what was your view strongly typed to earlier ? – Shyju Sep 07 '16 at 19:24
which comes from here `public class Homefront : DbContext { public DbSet Data { get; set; } }` – user979331 Sep 07 '16 at 19:24
Replace `Data` with `CentralParkPricing` in the ListViewModel view model. Ex : `public IEnumerable SinglesData` – Shyju Sep 07 '16 at 19:25
