Datagrid in Tabstrip - aber wie (C#)?

S

Stempi

Grünschnabel
Hallo zusammen

Versuche seit nunmehr Tagen einen Datagrid in ein Tabstrip einzubauen, bisher jedoch ohne Erfolg. Der Tabstrip läuft zwar, der Datagrid läuft ebenfalls, aber sobald ich den Code merge, kommt zwar keine Fehlermeldung aber auch kein Datagrid. Wo könnte das Problem liegen?

Für eure Ideen wäre ich sehr dankbar.

Gruss und bis bald,

Pat
