Salut j'utilise l'application block de validation pour valider mes objects. Cependant, j'ai une structure de classes qui doivent se faire validé en cascade

La voici

		}
 
		[NotNullValidator(MessageTemplate = "Required")]

		}

			{

				{

				}
			}
		}
 
	}

J'aimerais que l'objectValidator valide en cascade, c'est à dire, valider jusqua FlightScheduleRouting. Tout ca pour ne pas être obliger de validé object par object.

Qqn a déja utiliser cet application block ?
