System.TypeInitializationException à l'affichage d'un calendrier dans un TabControl

**sagaraph** · 24/05/2008, 03h38

Hello !

J'ai un gros problème avec mon application. J'ai crée un calendrier. Il s'affiche parfaitement quand j'utilise un Form. Par contre j'ai une erreur que je n'arrive pas à résoudre si j'utilise ce calendrier dans un TabControl. Le code est pourtant identique...

Voilà le détail complet de l'erreur:

L'exception System.TypeInitializationException n'a pas été gérée

Une idée ?

Hello !

Apparemment l'erreur viendrait de la classe cControlArrayUtils qui parcoure les contrôles de mon formulaire frmCalendar. Il faudrait la modifier pour qu'elle descende dans la hiérarchie et parcoure les contrôles contenu dans le TabControl.

Je n'ai pas codé cette classe et je ne sais pas comment faire pour qu'elle fonctionne comme décrit plus haut.

System.TypeInitializationException à l'affichage d'un calendrier dans un TabControl
