Problem with ORCA and DBGrid was created by Marcin W.

Hi!

1. Windows 10 Prof
2. CT 5.8
3. ZEOS components as data source from SQlite data base.
4. On form I put TD2Scene object, then TD2Background, and then TD2DBGrid.
5. I connect DBGrid to DataSource.
6. As far I don't create columns and connect them to the fields from DataSource, everything is fine.
But after connecting columns to fields, when I close application, it crashes.

greetings,
Marcin

I've just realized that problem does not occur when the base is empty.
Sample data in attachment.

For some time I also had problems with TD2DBGrid and I was not successful either. I had to use another grid.
See here
If the problem is resolved, I can reconsider using it again.

Guys
we "partial" fix the problem

Please TRY to Free TD2DBGrid before ZQuery1.close

procedure TForm1.FormClose(Sender: TObject; var CloseAction: TCloseAction);
begin
  FreeAndNil(DBGrid1); // SOS Free TD2DBGrid before ZQuery1.close
  ZQuery1.Close;
end;

In our tests (Win10-32 and Win10-64) work OK

PS: This sample is in Lab CT-CodeOcean now...

On Windows 10 Prof 64 and CT 5.8 it works too.
