To dispaly Custom Text when no records are found

Question

Hi ALL,

 

I want to display custom message " NO RECORDS" when user deletes all data entries from the grid.

 

Javascript CODE-

function Delete(altId) {
           var ctrlDeleteId = '.deleteAl' + alertId.toString();
           if (confirm('Are you sure you want to delete it?')) {
               $.post('Update.ashx', { AltId: altId, actionType: 'delete' }, function (data) {
                   if (data === 'Success') {
                       $(ctrlDeleteId).closest("tr").hide(300, function () { $target.remove(); });
                   }
               });
           }
       };

thanks,
