please help

how to update some fields after, update one field?

i try using event onValidate, but seems IB_Grid not refresh new fileds value

my code like this below:

procedure TForm.QueryValidateField(Sender: TIB_Statement;
ARow: TIB_Row; AField: TIB_Column);
begin
if not Assigned(AField) then exit;

if AField.FieldName='IDGOODS' then
begin
Query.FieldByName('Note1').AsString:= 'TEST1';
Query.FieldByName('Note2').AsString:= 'TEST2';
Query.FieldByName('Note3').AsString:= 'TEST3';
end;
end;

thanks.
