    <script  type="text/javascript">
        $(function () {
           $("#btnSave").click(function () {
                var checkedboxes =$("#dataTable  input:checkbox:checked").length;
                if (checkedboxes > 1)
                    return confirm("Do you want to Save " + checkedboxes + " records");
                else
                    return true;
            });
        });
</script>

<table id="dataTable">
