.NET Framework Class Library GridViewUpdatedEventHandler Delegate
Namespace:
System.Web.UI.WebControls
Assembly:
System.Web (in System.Web.dll)
Syntax
Public Delegate Sub GridViewUpdatedEventHandler ( _
sender As Object, _
e As GridViewUpdatedEventArgs _
)
public delegate void GridViewUpdatedEventHandler(
Object sender,
GridViewUpdatedEventArgs e
)
public delegate void GridViewUpdatedEventHandler(
Object^ sender,
GridViewUpdatedEventArgs^ e
)
type GridViewUpdatedEventHandler =
delegate of
sender:Object *
e:GridViewUpdatedEventArgs -> unit
Remarks
The GridView control raises the RowUpdated event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but after the GridView control updates the record. This allows you to provide an event-handling method that performs a custom routine, such as checking the results of an update operation, whenever this event occurs. When you create a GridViewUpdatedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
Examples
The following example demonstrates how to programmatically add a GridViewUpdatedEventHandler delegate to the RowUpdated event of a GridView control.

Notes
Le contrôle GridView déclenche l'événement RowUpdated lors d'un clic sur un bouton Mettre à jour (bouton dont la propriété CommandName a la valeur « Update ») situé dans le contrôle, mais après mise à jour de l'enregistrement par le contrôle GridView. Cela vous permet de fournir une méthode de gestion d'événements qui exécute une routine personnalisée, par exemple la vérification des résultats d'une opération de mise à jour, chaque fois que cet événement se produit. Lorsque vous créez un délégué GridViewUpdatedEventHandler, vous spécifiez la méthode qui gérera l'événement. Pour associer l'événement à votre gestionnaire d'événements, ajoutez une instance du délégué à l'événement. Le gestionnaire d'événements est appelé chaque fois qu'un événement se produit, sauf si vous supprimez le délégué. Pour plus d'informations sur les délégués de gestionnaires d'événements, consultez Événements et délégués.
