Add new template-Feld im datagrid,

in der Vorlage-Feld hinzufügen einer Beschriftung..

in der rowdatabound-Ereignis datgrid stellen Sie den label-text zu der Seriennummer.
http://bytes.com/topic/c-sharp/answers/874915-how-generate-serial-number-datagrid-view-automatically

Versuchen, diese...Bin nicht sicher, aber versuchen Sie dies.

Füllen einer datatable aus der Datenbank, und fügen Sie neue Spalte in der datatable

 DataColumn dcAuto = new DataColumn();
  dcAuto.AutoIncrement = true;
  dcAuto.AutoIncrementSeed = 1;
  dt.Columns.Add(dcAuto);

Binden, die die datatable an das gridview.

Ist dies so etwas wie Notwendigkeit zum hinzufügen von Seriennummern zu Ihren datgridview und Sie wollen, dass die Seriennummern zu handeln, wie Sie Aufzählungszeichen und zahlen in Microsoft word:- hier ist die Antwort. Sie können diese Methode aufrufen, in datagridview-Eigenschaften "RowsAdded" und "RowsRemoved"
