Hi! I don't quite understand how to change attribute values when some geoprocessing tool (e.g. "Calculate Field" is modifying rows. I want to change some attribute values within the same row event. I know how to do this in edit session (I followed this example and it works when I' m using Edit tab tools). But with Calculate Field using this parent Edit operation does not seem to work and I don't know why, although I get the operation from the RowChangedEvent.
