  AProperties1: TcxCustomEditProperties; const AValue1: Variant;
  ARow2: TcxGridDataRow; AProperties2: TcxCustomEditProperties;
  const AValue2: Variant; var AAreEqual: Boolean);
begin
  inherited;
  if (ARow1.Values[0] = ARow2.Values[0]) AND (ARow1.Values[1] = ARow2.Values[1]) then
    AAreEqual := True
  else
  AAreEqual := False;
