Remarques

Utilisez la ChangeMode méthode pour basculer par programmation le contrôle entre le DetailsView mode édition, insertion et lecture seule. Cette méthode met également à jour la CurrentMode propriété avec le mode spécifié. Le tableau suivant répertorie les différentes valeurs de mode.

Mode Description
DetailsViewMode.Edit Le DetailsView contrôle est en mode édition, ce qui permet à l’utilisateur de mettre à jour les valeurs d’un enregistrement.
DetailsViewMode.Insert Le DetailsView contrôle est en mode Insertion, ce qui permet à l’utilisateur d’ajouter un nouvel enregistrement à la source de données.
DetailsView.ReadOnly Le DetailsView contrôle est en mode lecture seule, qui est le mode d’affichage normal.
