JavaScript

<script type="text/javascript">
        $(document).ready(function () {
            $(".chkSelectAll").click(function () {
                var aa = $(this).attr("checked");
                if (aa) {
                    $(".checkbox-style-vertical").attr("checked", "checked");
                }
                else
                    $(".checkbox-style-vertical").removeAttr("checked");

            });
        });
    </script>

in the above jquery code i suppose that your select all check box has css class applied and its name is .chkSelectAll (please replace that class name with your original css class name)

i have used class name selector of jquery to select your all check boxes using ".checkbox-style-vertical" this class name, and also use attr method to set attribute to checked all the check boxes and removeattr to remove all the check boxes
