Subclassing a web page

[Negative0]

Can anyone explain to me how to subclass a webpage that someone else wrote with their codebehinds in C#?

One company we are working with wrote a few web pages that call their API. I want to add a smidgen of new functionality to it, while maintaining the same look and feel. I was told that I could subclass their page, but I have no clue on where to start on this. I would like to write my page using VB.net code behind, but I can do C# if necessary.

By "subclass" do you mean "derive from"?

I think thats right woss. They used the term subclass, so that is how I presented the issue here. What I want to be able to do is access some of the public (or protected) methods and variables they used in the code behind.

you would be looking to inherit a page from that page

in your standard code behind you usually have this
Inherits System.Web.UI.Page
so if you changed that to
Inherits SomeProject.SomePage

then you will inherit the page you want, which itself inherits from System.Web.UI.Page, so you get everything you need (this of course also needs to rely on the original programmer making everything accessable that you need to be)
