ListBox selection change does postback even though AutoPostBack is set to false for the ListBox
<p>The problem is described in the title. It does postbacking also when I specifically set AutoPostBack property of the ListBox to false, though it should be like that by default.
ListBox selection mode is set to multiple.</p>

<p>There is a similar <a href="http://stackoverflow.com/questions/4066977/firing-selectedindexchanged-event-but-the-listboxs-autopostback-property-is-f">question</a> but with a different background.</p>

<p>What am I missing? Is this some well known issue?</p>

<p>Thank you for replying,
please tell if you need the exact code</p>

<p>EDIT:</p>

<p>Here's the aspx page. Codebehind is much larger, since this page is the target of redirection, please tell if you need additional info from there.</p>
