Question

I am refactoring a web app built with previous versions of Asp.Net MVC where all the views have 2 codebehind files each.

Also if the views are working correctly I want to begin to remove all the code behind files as most of them are empty.

There are few of them that have properties like this in the codebehind:

public partial class List {
    public Message NewMessage { get { return new Message(); } }
}

Before completely removing them (I know this methods do not pertain to the views) how do I replicate them in the single page aspx or ascx?
I just tried to copy and paste the public methods in <% %> tags but this is not working.

May I ask why you were using this approach in the first place? I think you could achieve the same thing by making your View strongly typed, and pass the message as the View‘s Model.

Inherits="System.Web.Mvc.View<Message>"

If you already have a strongly typed View, you could make a custom class in your class library that has room for your message, for example

public class ModelWithMessage  {
    public Message Message { get; set; }
    public Object Model { get; set; }
    public ModelWithMessage(Message Message, Object Model) {
        this.Message = Message;
        this.Model = Model;
    }
}

You can of course make that type generic as well, allowing for a ModelWithMessage<T> construct and avoiding having to cast the Model to whatever type you need.

Another way to do it would be to use TempData. In your Controller, set

TempData["Message"] = "Hello world!";

Then in your View you write the message out simply with

<%= TempData["Message"] %>

Which approach you choose depends on what your Message class contains.
