Please ignore my previous chaotic post. Thanks for those who wanted to
help me and please let me know if you you see any problems in the
solution I found.

Public Class BasePage
Inherits System.Web.UI.P age

If IncludeTab Then

Now I am thinking better not posting, it's not a big deal, I've just
moved the dynamic control inclusion from CreateChildCont rols into
Render.
What was the problem: CreateChildCont rols fires after Page_Load ( page
load event) except some cases (a usercontrol in a page contains a
button, click on the button and the order is changed!!!). So, in this
case CreateChildrenC ontrols fires first, and of course Page_Load can't
set some properties inside the BaseClass.
I've spent a day learning the way Microsoft implemented this model and
that there's reasons behind. It didn't help me of course cause it
didnt give me a solution but only reasons why things work the way they
work.
I came with this solution which I hope it's a good one .... pls let me
know if you see anything wrong here.
Thanks,

I have a base class which overrides CreateChildCont rols / Render.
Inside CreateChildCont rols, based on a public property ShowLinks in
this class, I can include/display a usercontrol (kind of set of links
like a menu)
A form P inherits this base class. I set the property me.ShowLinks =
true on the load event of P.
P contains another usercontrol (C) which has a button on it.
When I first call P, everything renders fine. First it goes on P_Load,
C_Load, BaseClass:Creat eChildControls and Render. Depends on ShowLinks
property, the links are properly displayed on the page.
The problem is when I press the button from the C control, it changes
the order, it first go to CreateChildCont rols, it doesn't have
ShowLinks set at this moment, it goes afterwards to Load and the Links
do not display properly.
How can I fix this issue?
Thanks
