notice that the following checkbox (cbHeader1) did not check all gridview checkboxes.


<script type='text/javascript' src="../Scripts/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        var chkBox = $("input[id$='cbHeader1']");
        chkBox.click(
                    function () {
                        $("#gvStudent INPUT[type='checkbox']")
                        .attr('checked', chkBox
                        .is(':checked'));
                    });
        // To deselect CheckAll when a GridView CheckBox        // is unchecked       
                    $("#gvStudent INPUT[type='checkbox']").click(
                    function (e) {
                        if (!$(this)[0].checked) {
                            chkBox.attr("checked", false);
                        }
                    });
    });

          
                 
</script>
