使用RadioButtonFor在ViewModel中设置布尔值？

Question

I have a fairly complex form, but the problem I'm having is with a very basic part of it. I have a radio button group with two radio buttons to represent a true or false value for a bool within my view model. So I have a model like this:

public class MyViewModel {
    public bool IsPOBox { get; set; }
}

Then within my view I have the following code to produce the radio buttons:

@Html.RadioButtonFor(m => m.IsPOBox, true, new { id = "togglePOBoxOn" }) @Html.Label("togglePOBoxOn", "PO Box")
@Html.RadioButtonFor(m => m.IsPOBox, false, new { id = "togglePOBoxOff" }) @Html.Label("togglePOBoxOff", "Street Address")

The problem is, when I submit this with "PO Box" selected, the IsPOBox property is being set to false instead of true . In fact, the property is set to false regardless of which radio button is selected.

Have I messed something up here?

It turns out ASP.NET MVC doesn't include disabled fields' values when you submit a form. The field was being disabled by a checkbox further up in the form. Annoying!

Edit: After seeing @JohnSaunders' comment below I did a quick search for how I'm supposed to have an uneditable field, but still have the information submitted. It turns out you should use the readonly attribute. I learned something today!

ie <input type="text" readonly />
