Re: Dynamic WebControl events...

I believe that the "catching up" of the lifecycle is for the *control's*
lifecycle - not the Page. Since it is the Page lifecycle that populates
viewstate and the IPostBackHandler data, missing the Page lifecycle does
not get those actions done. However, all of the control lifecycle events
(Init, Load, etc.) would be fired.

As a confirmation of this, I moved the checkbox creation to
Page_PreRender, and it does *not* maintain viewstate or trigger the
event handler - both of which would have already passed in the Page
lifecycle.

This is incorrect.
Control's life cycle begins after they have been added to their parent
controls; so, even if you add a Control to another Controls collection
in the Page PreRender event, it will still fire its postback events...
As Stacey pointed out, setting the AutoPostback property to true will
solve this problem.
