DBAdvGrid editor with dinamic button caption

I have a DBGrid with a edButton column.

I would like to change the caption on the button in every row depending on another field value.
Which event I have to handle ? Something like OnGetDisplText, but for the button caption?

There was not a way to do this in the current version.
We did a small adaption to make it possible from the next version via:


procedure TForm5.DBAdvGrid1GetCellColor(Sender: TObject; ARow, ACol: Integer;
  AState: TGridDrawState; ABrush: TBrush; AFont: TFont);
begin
  if acol = 2 then
  begin
    DBAdvGrid1.Columns[2].ButtonCaption := inttostr(arow);
  end;
end;
