            function searchTable(inputVal) {
                var table = $('#GridView1');
                table.find('tr').each(function (index, row) {
                    var allCells = $(row).find('td');
                    if (allCells.length > 0) {

                    return false;
                }});

var gv = document.getElementById("#GridView1");

    for (var i = 0; i < gv.all.length; i++) {
var cellValue = grid.rows[i].cells[0].elements[0];
cellValuestyle.background = '#DD00DD';
}
