How to Bind an IList to a View in MVC 4?

Bind to a List in MVC 4

Binding an IList to a view in MVC 4 can be achieved through the following steps:

Define a ViewModel with a List property:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

In the View, create a form and iterate through the list to render input fields:

@model MyViewModel

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

In the Action, receive the posted ViewModel:

[HttpPost]public ViewResult(MyViewModel vm)
{
...
}

Note that only properties with inputs in the form will be populated in the postback. If properties are conditionally hidden, gaps in the ID sequence will cause binding issues for subsequent items.
