Hi,
I need this functionality for a TcxGridMasterDataRow not TcxGridGroupRow. I applied the same logic for TcxGridMasterDataRow but that doesn't work. Maybe i wasn't clear what i wanted, i just want to hide the [+/-] button but still have the ability to expand the row with Left/Right keys.
with Result := not RecordInfo.Expanded in function TcxACGridMasterDataRow.GetExpandable i can expand the row but the button still show
with Result := False in function TcxACGridMasterDataRow.GetExpandable the button doesn't show but the row doesn't expand either
Second our grids are on inherited forms, which means all logic applied on the designtime view need to reapplied to the new view. That's alot off work just to hide (not show) a button…
Greetings,
