Data Access Pages

Hi,

I am new to creating data access pages and what I am trying to do is
create a page that will allow users to update projects and add new
projects. I am trying to insert a tabstrip control so I can update
projects on one tab and add new projects on the other but when I do
this both tabs display the same thing. How do I create a page that
can do different things on different tabs? All I really need is a
fairly simple example to get started. Thanks.
