asp.net mvc - How to extend html.textboxfor to remove the name attribute?

Question

I want to extend the helper to make it like this:

@html.TextBoxFor(x=>x.CustomerId).ReadOnly()

and output the input element without the name attribute, so that it will not be posted to the server.

Answer 1

This should do the trick:

public static class MyInputExtensions
{
    public static MvcHtmlString NameLessTextBoxFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression)
    {
        var textBox = htmlHelper.TextBoxFor(expression);

        string pattern = @"name=""([^""]*)""";

        string fixedHtml = Regex.Replace(textBox.ToHtmlString(), pattern, "");

        return new MvcHtmlString(fixedHtml);
    } 
}

Usage:

@Html.NameLessTextBoxFor(x=> x.CustomerId)
