Hi, I do need to format the data but no examples from the linked site seem to work as they all work on an input box and I am not sure how to pass in the cell data for formatting. I have tried a few things but all of them break the grid. I can get the date format to work fine off the datepicker format example you gave just not the datetimepicker you linked.
obj.colModel[9].render = function (ui)
{
var cellData = new Date(ui.cellData);
return $.datetimepicker({ dateFormat: "yy-mm-dd", timeFormat: "hh:mm:ss" }, cellData);
}
