Dafür hat BugFix das passende geschrieben . Schau mal hier ListView - Editieren aller SubItems. 
Hat denn niemand eine Idee? 
Kannst du den Code so posten, dass man schnell testen kann?
Was ist denn los? Warum antwortet denn niemand 
Hi,
wenn ich das Debugging hinzufüge, dann geht es zumindest einmal Mal 
Mal sehen woran es liegt
