I understood!
There is no need use updaterow function, just use cellsrenderer.
Sample cellsrenderer function:
var cellsrenderer = function (row, columnfield, value, defaulthtml, columnproperties) { var data = $("#jqxgrid").jqxGrid('getrowdata', row); if (data.isCheck) { return '<span style="margin: 4px; float: ' + columnproperties.cellsalign + '; font-weight: bold; text-decoration: underline">' + value + '</span>'; } else { return '<span style="margin: 4px; float: ' + columnproperties.cellsalign + '; font-weight: normal;">' + value + '</span>' }}
Where variable isCheck is a input checkbox.
