Hello
Checkboxes in indicator column is a reflaction of TDBGridEh.SelectedRows property.

Here is an example of using SelectedRows

Code:
procedure TForm1.Button1Click(Sender: TObject);
var
  s: String;
  i: Integer;
begin
  DBGridEh1.DataSource.DataSet.DisableControls;
  s := '';
  for i := 0 to DBGridEh1.SelectedRows.Count-1 do
  begin
    DBGridEh1.DataSource.DataSet.Bookmark := DBGridEh1.SelectedRows[I];
    s := s + IntToStr(DBGridEh1.DataSource.DataSet.RecNo) + ',';
  end;
  DBGridEh1.DataSource.DataSet.EnableControls;

  ShowMessage('Selected Records are: ' + s );
end;


Best regards
Admin

Teacher Admin,
Plz ignore my last question.
It works after I set the dgMultiSelect to be true.

Thanks.
