How to build a control with multiple codebehind

Is there someway to build a control and bind multiple codebehind files againts it.
So we can seperate the code among multiple controls and not using inheritance!
It works when I do it static, but i would like it to be dynamic, but then the binding of the attributes does not work
Below is a simple example that works like this:
1. first i create a interface control that holds all the attributes of the ascx
2. then i create two extra codebehind controls that seperates the attributes of the interface

4. then we attach the codebehind controls to the control tree of the interface.

Code (put this in a single apsx page and see how it works)
<%@ Page Language="C#" AutoEventWireup="true" %> Code 1: <asp:Literal ID="ltlCode1" runat="server" /><br /> Code 2: <asp:Literal ...
