I'm trying to figure out why when I click Remove on any listbox the postback doesn't refresh the listbox to show the change. I thought that every updatepanel refreshes. If this is so, then why isn't my listbox automatically reloading the updated list after I remove an item? I end up having to refresh the whole page manually in order to see any removed items from my listboxes

Hello,
How do you get the data into the listbox? Try this:
for example the list box inside this updatePanel
<asp:updatepanel id="CuentUpdatePanel" runat="server">
<contenttemplate>
<asp:listbox id="lbCuent" runat="server" width="214px" /><br />
</contenttemplate>
</asp:updatepanel>
After you click Remove, for sure you have to call a function right? In that function, also call: CuentUpdatePanel.Update()
This will update the UpdatePanel ... and if your list box uses a ObjectDataSource ... example below
<asp:updatepanel id="CuentUpdatePanel" runat="server">
<contenttemplate>
<asp:listbox id="lbCuent" runat="server" DataSourceID="GetListITems" width="214px" /><br />
</contenttemplate>
</asp:updatepanel>
then in your function, you do this: lbCuent.Databind();
Hope it helps ... by the way, next time don't bother post all of your HTML in here, too much, waste your time. =) just the part that you have problem is enough already ... and the code behind that is related to it ... Cheers
The problem is that I didn't rebind my listbox after whatever event (insert, delete, etc.)
I didn't even have to call the .Update() manually, it all works fine now after the obvious missing rebind of my listbox controls
