Question

I’m using this jquery multiselect control on an asp.net webforms page. Here is the code:

<script type="text/javascript">
    $(document).ready(function () {
        $(".multiselect").multiselect();
    });
</script>

<asp:listbox runat="server" CssClass="multiselect">
    <asp:ListItem Value="1">foo</asp:ListItem>
    <asp:ListItem Value="2">bar</asp:ListItem>
</asp:listbox>

<asp:Button runat="server" Text="save" OnClick="SaveClick"/>

My SaveClick event is empty, so only a postback is being performed. If I select both items in my multiselect dropdown, and then click submit, only the last item is selected. I found one similar issue here, but it doesn’t seem to apply to asp.net. Anyone figured this one out?

I forgot to set SelectionMode=”Multiple”
