Hallo,

ich möchte eigentlich nichts weiter tun, als über ein Formular eingegebene Daten in eine Datenbank (AccessDataSource) zu schreiben. Das soll parametergesteuert geschehen:

Code :
1
2
3
4
5
6
7
8
9
10

Die angesprochenen Formularfelder werden im Anschluss an die Abfrage aufgebaut, z.B.:

Drückt man jedoch im Formular auf "Absenden", erscheint folgende Fehlermeldung:


Serverfehler in der Anwendung /.

Das Steuerelement f_ddlDiszplinen konnte in ControlParameter disziplin_id nicht gefunden werden.

Beschreibung: Unbehandelte Ausnahme beim Ausführen der aktuellen Webanforderung. Überprüfen Sie die Stapelüberwachung, um weitere Informationen über diesen Fehler anzuzeigen und festzustellen, wo der Fehler im Code verursacht wurde.

Ausnahmedetails: System.InvalidOperationException: Das Steuerelement f_ddlDiszplinen konnte in ControlParameter disziplin_id nicht gefunden werden.
Wahrscheinlich ist der Fehler mal wieder überaus banal, ich finde ihn nur nicht

Bin für jegliche Hinweise dankbar!
