aspx_beginners thread: Why are there TWO bubble events from ONE click?

Hi,
I can't work out why clicking ONCE on the button in User_Control.ascx
causes TWO bubble events to fire in the parent page Main_Page.aspx (all
code below).
Both events are reported in the main page as having the same source object
(unsurprisingly, the button), but have different event arguments (the
first "System.EventArgs", the
second "System.Web.UI.WebControls.CommandEventArgs").
Can anyone tell me what on earth is going on?
Thanks!
JON

Try adding AutoEventWireup=false to your Page directive.

Hi,
I changed the first line on MAIN_PAGE.aspx to
<%@ Page Language="VB" AutoEventWireup="false" %>
and it doesn't seem to have helped - I'm still getting the same TWO bubble
events as before.
Any other ideas?
Thanks,
JON
