Asp.net MVC , CheckBoxs not binding in case of list - asp.net-mvc-4

Question

Though it seems like it has been discussed earlier also , but I could not find the solution -:
I have a VM like this-:
public class RoomsVm
{
public RoomsVm()
{
Rooms.Add(new Room()
{
IsVip = true,Id = "1"
}
);
Rooms.Add(new Room()
{
IsVip = false,
Id = "2"
}
);
}
public List<Room> Rooms=new List<Room>();
}
public class Room
{
public bool IsVip { get; set; }
public string Id { get; set; }
}
My controller has 2 simple actions- 1- for get and 2 for post-:
public ActionResult IndexView2()
{
var roomVM = new RoomsVm();
return View(roomVM);
}
[HttpPost]
public ActionResult IndexView2(RoomsVm roomsVm)
{
return View(roomsVm);
}
In my view - I simply display my rooms with check boxes like this-:
#model MVCApplication.Models.RoomsVm
<h2>IndexView2</h2>
#using (Html.BeginForm())
{
for (int i = 0; i < Model.Rooms.Count(); i++)
{
#Html.CheckBoxFor(modelItem=>modelItem.Rooms[i].IsVip,new{value=Model.Rooms[i].Id})
}
<input type="submit" value="Submit"/>
}
Problem- When I click Submit button, I don't get updated values of rooms checkboxes in input value of Post action ..
What wrong am I doing ?

Answer 1

You don't have accessors on your Rooms property
public class RoomsVm
{
public RoomsVm()
{
Rooms = new List<Room>(); // Initialize rooms
Rooms.Add(new Room() {.... //Add rooms
}
public List<Room> Rooms { get; set; } // Add get/set
}
