Ajax AccordionPane problem

[Kursat]

Hi,

I have two accordion panes on a page and one of them includes a
DropdownList. I want to fill that DropdownList on page load but null
reference error occurs if the AccordionPane on which the DropdownList
exists is collapsed . As far as I understand child controls of an
AccordionPane created at the time it is expended. Well but how can I fill my
little poor DropdownList with some data?

Thanks in advance.
