                    public void finish(MessageBoxResult result) {
                        if (result == MessageBoxResult.Yes)
                            //...
                    }

                    @Override
                    public void dialogClosed() {
                    }
                });

Answer 2

dialog.setCancelable(true); should be like  dialog.setCancelable(false);

It prevents closure of alert dialog when user presses back button :)
