Code-Behind Pages

Pages without code-behind are another story. They are compiled into a code-behind class when run, but you cannot actually tell it to inherit from another class which is why code-behind pages are better for this.

Code-behind pages are the "raw page code" and allow you to do all of this fancy inheritance from the Page class.

Take a look at your code-behind page -

Public Class cdo Inherits System.Web.UI.Page

You can see here that the code-behind class is just an inherited Page class as well (sure is a useful class eh?)

Well, enough of this stuff, let's get into these page classes.
