Question

I have two models:

class ModelIn{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Address { get; set; }
}

class ModelOut{
    public ModelOut(){ People = new List<ModelIn>();}
    public List<ModelIn> People { get; private set;}
    public string Country { get; set; }
}

And I have Controller editing ModelOut:

public ActionResult People()
{
    ...
    return View(SomeModelOutInstanceWith3People);
}
[HttpPost]
public ActionResult(ModelOut items)
{
    ...
}

In view I have sth like:

<% using (Html.BeginForm()) { %>
    <%: Html.EditorFor(m => Model.Country) %>
    <% for(int i = 0; i < Model.People.Count; ++i){ %>
        <%: Html.EditorFor(m => Model.People[i].FirstName) %>
        <%: Html.EditorFor(m => Model.People[i].LastName) %>
        <%: Html.EditorFor(m => Model.People[i].Address) %>
    <% } %>
    <input type="submit" />
<% } %>

It works all OK, but in post action I have empty ModelOut items.
I can see in logs that data is sent correctly.

I have tried everything, nothing works.

Answer 1

@Dai were right. MVC let me use items for model instance name when it is instance of List, but doesn’t let me use it for ModelOut.

After renaming items to model it works fine.
