ASP.NET MVC Checkbox Group

Question

I am trying to formulate a work-around for the lack of a \"checkbox group\" in ASP.NET MVC. The typical way to implement this is to have check boxes of the same name, each

I don't know how to solve your problem, but you could define your checkboxes with this code:

<%= Html.CheckBox("n[0]") %><%= Html.Hidden("n[0]",false) %>
<%= Html.CheckBox("n[1]") %><%= Html.Hidden("n[1]",false) %>
<%= Html.CheckBox("n[2]") %><%= Html.Hidden("n[2]",false) %>

Hidden fields are needed, because if checkbox is not checked, form doesn't send any value. With hidden field it sends false.

Your post method will be:

[HttpPost]
public ActionResult Test(bool[] n)
{
    return View();
}

It may not be optimal and I am open to comments, but it works:)

EDIT

Extended version:

<%= Html.CheckBox("n[0].Checked") %><%= Html.Hidden("n[0].Value",32) %><%= Html.Hidden("n[0].Checked",false) %>
<%= Html.CheckBox("n[1].Checked") %><%= Html.Hidden("n[1].Value",55) %><%= Html.Hidden("n[1].Checked",false) %>
<%= Html.CheckBox("n[2].Checked") %><%= Html.Hidden("n[2].Value",76) %><%= Html.Hidden("n[2].Checked",false) %>

Your post method will be:

[HttpPost]
public ActionResult Test(CheckedValue[] n)
{
    return View();
}

public class CheckedValue
{
     public bool Checked { get; set; }
     public bool Value { get; set; }
}

I wrote it without VS, so it may need little correction.
