I'm creating unidbgrid and it's partially working, I'm not able to set the Filtering.editor property to below the code I'm doing.       Grade.Columns.Clear;     Grade.Columns.BeginUpdate;     tmpCons.first;     while not tmpCons.eof do     begin         with Grade do         begin             with Columns.Add do             begin               FieldName     := tmpCons.fieldbyname('campo').asstring;               Title.Caption := tmpCons.fieldbyname('titulo').asstring;               Width
