Web custom controls issue

[Emanuele]

Hi all,
i am developing a web custom control. Basically it's something like a
listbox, a bit enhanced. i have some problem when i have to add items to the
controls. this is the basic structure of the control:

CREATECHILDCONTROLS (method)
create the child controls of the component.
add the items inserted (if i don't add them here, i can't handle item
events)

RENDERCONTENTS
render the control and each item i have inserted.

---- IMPLEMENTATION IN A WEBFORM ---

the control is added in a Webform, and from a dorpdownlist the user can
choose which "set" of items explore. obviously, in the SELECTEDINDEXCHANGED
event of the dropdownlist i populate the custom control, but i can't see
anything.

i have found the problem: the items contained are not rendered because the
CREATECHILDCONTROLS is called before the SELECTEDINDEXCHANGED, thus i don't
have items added and created in the controls collection of the custom
control...

can anyone help me, please? i really don't know how to manage it...

Might be off topic, but you do realize that there's commercial and
open source solutions available for mostly everything you
could possibly imagine in a "drop down list"...??
Oe of them is http://ajaxwidgets.com which has an AutoCompleter
control, fully ajax enabled...
