C#-Druckbeleg, Vorkalkulation, Rechnung ⇐ C#

[Guest]

Wenn ich weniger oder gleich 15 Elemente hinzufüge, ist es in Ordnung, aber wenn ich mehr als 15 Elemente hinzufüge, sollte es zur nächsten Seite gehen, aber das Programm erstellt unendlich viele Seiten und wenn ich Esc drücke, stoppt es, erstellt aber nur Kopien der ersten Seite, nicht 16. 17.... Element auf der nächsten Seite, kopiert nur die erste Seite unendlich oft. Es gibt keine weiteren Probleme, es druckt gut, die Verbindung zum Drucker funktioniert einwandfrei.
