I am in the process of upgrading my users to the newest version of ArcGIS Pro 2.4.3 and testing my code. It appears that CancelEdit is not performing as expecting in the OnRowChangeEvent? It seems to work in OnRowDeleteEvent but not in OnRowChange?
else if (ConditionTrue) //rollback
//CANCEL the Redraw Change
args.CancelEdit(() => ChangeError("Changes Not Allowed!", "Parent Shape Cannot be changed"));
I also put in simply args.CancelEdit() and that failed too
