 datatype: "json",
    colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'],
    colModel:[

    pager: '#pager15',
    sortname: 'id',
    viewrecords: true,
    sortorder: "desc",
 loadComplete: function(){
  var ret;
  if (sw==0) {
  alert("This function is executed immediately after\n data is loaded. We try to update data in row 6.");
  ret = jQuery("#list15").jqGrid('getRowData',"6");
  if(ret.id == "6"){
   jQuery("#list15").jqGrid('setRowData',ret.id,{note:"<font color='red'>Row 6 is updated!</font>"})
  }
  
  sw = 1;}
 }
});
jQuery("#sids").click( function() {
    jQuery("#list15").jqGrid('setSelection',"6");
 //alert("Id's of Grid: \n"+jQuery("#list15").jqGrid('getDataIDs'));
});
