ListControl and Postback

[SK]

Hello,

I have a list control, with multiselection enabled. Now
when the user selects something the first time from it,
then I can easily write out the selected items, but on
postback I cant do that, although they are selected.
I mean I can print the selected items, but I cant do it
after the postback. It behaves like there is no selected
item, but i can see that they are selected.

Any idea?
