I am editing file geodatabase using edit toolbar. I've writing an extension to listen to edit events. It gives me the new feature with OnChangeFeature. However I am trying to obtain the original feature as well as a log of edits made. I've tried OnStartOperation but IWorkspaceEdit::EditDataChanges some how comes back null for file gdb. I could try to listen to OnSelectionChanged event but sometimes features attributes can be edited without selecting the row. ideas?
