How do I make a textbox readonly only for a specific MVC Action?

Question

The title might be confusing, so here is my problem: I'd like in my View a readonly textbox only if my Action is for editing (something like EditLocation) and if my Action is intended for adding a new record (AddLocation), I'd like an editable textbox.

My ff. code works, but I was wondering if there's a "cleaner" solution

@using (Html.BeginForm(Model.Location.Id == 0 ? "AddLocation" : "EditLocation", "Location"))
    {
        <fieldset>
            @Html.HiddenFor(x => x.Location.Id)
            @Html.HiddenFor(x => x.Location.CompanyGroupId)
            @Html.HiddenFor(x => x.CompanyGroup.Id)
            @Html.HiddenFor(x => x.CompanyGroup.Code)

            <div class="form-group">
                <strong><span>@ResourcesCommon.Location_Code</span></strong>
                @if (Model.Location.Id == 0)
                {
                    @Html.TextBoxFor(x => x.Location.Code, new { @class = "form-control" })
                    @Html.ValidationMessageFor(x => x.Location.Code)
                }
                else
                {
                    @Html.TextBoxFor(x => x.Location.Code, new { @class = "form-control", @readonly = "readonly" })
                    @Html.ValidationMessageFor(x => x.Location.Code)
                }

            </div> ...

Thanks and have a good week ahead!

This might help you:

@Html.TextBoxFor(x => x.Location.Code, new Dictionary<string, object>() .AddIf(true, "@class", "form-control") .AddIf(Model.Location.Id != 0, "@readonly", "readonly"))

// This returns the dictionary so that you can "fluently" add values
    public static IDictionary<TKey, TValue> AddIf<TKey, TValue>(this IDictionary<TKey, TValue> dictionary, bool addIt, TKey key, TValue value)
    {
        if (addIt)
            dictionary.Add(key, value);
        return dictionary;
    }

I took it from another stackoverflow post long back which i don't have the link.
