Question

I am learning MVC from Stephen Walther tutorials on MSDN website. He suggests that we can create Html Helper method.

Say Example

using System;
namespace MvcApplication1.Helpers
{
          public class LabelHelper
          {
               public static string Label(string target, string text)
               {
                    return String.Format("<label for='{0}'>{1}</label>",
                    target, text);
               }
          }
}

My Question under which folder do i need to create these class?

View folder or controller folder? or can i place it in App_Code folder?

Answer 1

I would create a subfolder Extensions in which define helper methods:

namespace SomeNamespace
{
    public static class HtmlHelperExtensions
    {
        public static string MyLabel(this HtmlHelper htmlHelper, string target, string text)
        {
            var builder = new TagBuilder("label");
            builder.Attributes.Add("for", target);
            builder.SetInnerText(text);
            return builder.ToString();
        }
    }
}

In your view you need to reference the namespace and use the extension method:

<%@ Import Namespace="SomeNamespace" %>

<%= Html.MyLabel("abc", "some text") %>
