MVC radio buttons disabled readonly when not authenticated

@Html.RadioButtonFor(modelItem => item.CheckerApproved, true)
@Html.LabelFor(modelItem => item.CheckerApproved, "Accepted")
@Html.RadioButtonFor(modelItem => item.CheckerApproved, false)
@Html.LabelFor(modelItem => item.CheckerApproved, "Rejected")

What I'm wanting is for some way to make these disabled or readonly when the user isn't Authenticated.

ie. Enabled when:

HttpContext.Current.User.Identity.IsAuthenticated

Is there an easy way to do this? Would you put them on some sort开发者_如何转开发 of panel? Not sure for MVC?

Would you set there enabledability individually for each line?

A more than excellent candidate for a custom helper:

using System;
using System.Linq.Expressions;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;

public static class RadioExtensions // LOL for this name
{ 
    // TODO: Pick a better name here than MyRadioButtonFor
    public static IHtmlString MyRadioButtonFor<TModel, TProperty>(
        this HtmlHelper<TModel> html,
        Expression<Func<TModel, TProperty>> ex,
        object value
    )
    {
        var isAuthenticated = html.ViewContext.HttpContext.User.Identity.IsAuthenticated;
        if (isAuthenticated)
        {
            return html.RadioButtonFor(ex, value);
        }
        // Remark: adapt with readonly if necessary,
        // note that there is a crucial difference between a readonly and disabled
        // element in HTML. Up to you to pick the desired behavior
        return html.RadioButtonFor(ex, value, new { @disabled = "disabled" });
    }
}

and in your view simply consume the fruits of your labour:

@Html.MyRadioButtonFor(modelItem => item.CheckerApproved, true)
@Html.LabelFor(modelItem => item.CheckerApproved, "Accepted")
@Html.MyRadioButtonFor(modelItem => item.CheckerApproved, false)
@Html.LabelFor(modelItem => item.CheckerApproved, "Rejected")
