Does ReadOnly(true) work with Html.EditorForModel?

Consider the following setup:

Model:

public class Product
{
    [ReadOnly(true)]
    public int ProductID
    {
        get;
        set;
    }

    public string Name
    {
        get;
        set;
    }
}

View:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" 
Inherits="System.Web.Mvc.ViewPage<MvcApplication4.Models.Product>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <%= Html.EditorForModel() %>
</asp:Content>

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new Product
            {
                ProductID = 1,
                Name = "Banana"
            });
    }
}

There result is this: alt text

I was expecting that the ProductID property was not going to be editable via the ReadOnly(true) attribute. Is this supported? If not is there any way to hint ASP.NET MVC that some properties of my model are read-only? I would not like to just hide ProductID via [ScaffoldColumn(false)].

I solved this problem by adding a UIHintAttribute to the property on my class of "ReadOnly".

[UIHint("ReadOnly")]
public int ClassID { get; set; }

Then I simply added a ~\Views\Shared\EditorTemplates\ReadOnly.ascx file to my project with this in it:

<%= Model %>

A really simple way to add custom templates, you could include formatting or whatever.
