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...
