Listbox on Postback

[Danno]

Ok, I'm losing my mind. I have a simple ASP.NET page with a listbox
control. I am loading the listbox with a few items during Page_Load,
but only if it is NOT postback (the listbox is unbound, the items come
from XML).

I select an item from the list and click a Delete button, but on
postback the SelectedIndex property is always = 0 (unless I don't
select an item and then I get -1).

EnableListView is true for the page and the listbox.

Any ideas?

viewstate is on?

Even I am facing the same problem. EnableViewState is true.
What might be the problem?

Yeah, sorry. I meant to say EnableViewState (not EnableListView) is
on for the form and listbox.
