We have a few pages that use listboxes. They are declared as, for example:
<asp:ListBox ID="lst_Res" SelectionMode="Multiple" AutoPostBack="true" Style="font-family: Arial;
font-size: x-small" runat="server" Height="150px" CssClass="NoPrint" />
This works fine as long as we hold down ctrl or use shift. Any computer tech will feel at home with this. But many users don't know that you need to hold ctrl. So I was wondering if it was possible to make a listbox where you don't have to hold ctrl. Clicking on any item will simply select/deselect it. Note that it still has to submit a postback after each change.
