Event firing problem

I create a simple web page, put on a couple of
<asp:listboxes with
autopost=true. I then write code in the events behind
them, doing some simple stuff like using the values in the
first listbox to effect the values in the second listbox
(with a button to fire off Page_Load, which processes the
selected values in the listboxes). When I step through
them in the debugger I see that the events behind the
listboxes fire when I select values in the listboxes, and
Page_Load doesnt fire until I click on the button -
exactly as I expect.

However, when I take the same listboxes and place them in
a web control (which inherits it a base class), Page_Load
is always called when I select items in the listbox (after
Page_Load processes the event behind listbox is fired, but
the damage is done) - NOT what I want.

I would like to solve this myself, but so far all Ive done
is spent a lot of quality time in the debugger, and
deadlines loom near. Can someone please give me some
ideas on how to solve this, where to start looking?

Thanks much, Mark
 
Page.IsPostback to populate the first listbox ("lc1"); the
SelectedIndexChanged event for lc1 is used to populate the
second listbox ("lc2").
