Hi Thanks for the guide - I can see that the rows are now traversed but class is not added to row, my code is
load: function(evt, ui){
var $grid = $(this),
data = $grid.pqGrid('option','dataModel.data');
$.each(data, function (i, rowData) {
if (rowData[2] == "true") {
$grid.pqGrid("addClass", { rowIndx: i, cls: "pq-red" });
}
});
},
