ASP.NET - AJAX and jQuery on the same screen

Don't use  $(document).ready(function()  as it will not work with Ajax.
Use pageLoad() instead

        function pageLoad(){
            $('#gvReport tr[class="ItemStyle"],#gvReport tr[class="AlternatingItemStyle"]')
            .bind('mouseover', function() { $(this).css('background-color', '#6E6E6E') })
            .bind('mouseout', function() { $(this).css('background-color', '') });
        }
