<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/css/bootstrap.min.css"
        rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>
    <link href="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/css/bootstrap-multiselect.css"
        rel="stylesheet" type="text/css" />
    <script src="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/js/bootstrap-multiselect.js"
        type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            $('[id*=lstCountries]').multiselect({
                includeSelectAllOption: true
            });
        });
    </script>
    <asp:ListBox ID="lstCountries" runat="server" SelectionMode="Multiple">

        foreach (ListItem item in lstCountries.Items)
        {
            if (item.Selected)
            {
                message += item.Text + " " + item.Value + "\\n";
