[ASP2.0][BUG?] DropDown lost selectedValue at different bind

[Pablo]

Hi at all!
I have a problem (what's new! ).
I have two dropDown and two ODS.
The dropDown filter each other at postback.
When I select an item of the first DD, it fire a postback and filter
the second DD.
Now: If i select an item of the second DD, it fire a second postBack
and filter the first DD.
The first DD have some item and the past selected Item...but it's NOT
SELECTED!!!
AArgh...how can i mantein the selected item at different databind?
Ps: the value and the text are the same at every filter!

Tnx at all for any comments!
Ps: sorry for my english, guy
