Answer 1

I achieved it using some extension methods

private const string endFieldPattern = "^(.*?)>";

    public static MvcHtmlString IsDisabled(this MvcHtmlString htmlString, bool disabled)
    {
        string rawString = htmlString.ToString();
        if (disabled)
        {
            rawString = Regex.Replace(rawString, endFieldPattern, "$1 disabled=\"disabled\">");
        }

        return new MvcHtmlString(rawString);
    }

    public static MvcHtmlString IsReadonly(this MvcHtmlString htmlString, bool @readonly)
    {
        string rawString = htmlString.ToString();
        if (@readonly)
        {
            rawString = Regex.Replace(rawString, endFieldPattern, "$1 readonly=\"readonly\">");
        }

        return new MvcHtmlString(rawString);
    }

and then....

@Html.TextBoxFor(model => model.Name, new { @class= "someclass"}).IsDisabled(Model.ExpireDate == null)
