Hinweise

Das ItemCommand Ereignis wird ausgelöst, wenn auf eine Schaltfläche innerhalb des FormView Steuerelements geklickt wird. Dadurch können Sie eine Ereignisbehandlungsmethode bereitstellen, die eine benutzerdefinierte Routine ausführt, wenn dieses Ereignis auftritt.

Schaltflächen in einem FormView Steuerelement können auch einige der integrierten Funktionen des Steuerelements aufrufen. Um einen dieser Vorgänge auszuführen, legen Sie die CommandName -Eigenschaft einer Schaltfläche auf einen der Werte in der folgenden Tabelle fest.

CommandName-Wert BESCHREIBUNG
"Abbrechen" Bricht einen Bearbeitungs- oder Einfügevorgang ab und gibt das FormView Steuerelement in den von der DefaultMode -Eigenschaft angegebenen Modus zurück. Löst die ModeChanged Ereignisse und ModeChanging aus.
"Löschen" Löscht den aktuellen Datensatz. Löst die ItemDeleted Ereignisse und ItemDeleting aus.
"Bearbeiten" Versetzt das Steuerelement in den FormView Bearbeitungsmodus. Löst die ModeChanged Ereignisse und ModeChanging aus.
"Einfügen" Fügt den aktuellen Datensatz in der Datenquelle ein. Löst die ItemInserted Ereignisse und ItemInserting aus.
"Neu" Versetzt das Steuerelement in den FormView Einfügemodus. Löst die ModeChanged Ereignisse und ModeChanging aus.
"Seite" Führt einen Pagingvorgang aus. Legen Sie die CommandArgument -Eigenschaft der Schaltfläche auf "First", "Last", "Next", "Prev" oder eine Seitenzahl fest, um den Typ des auszuführenden Pagingvorgangs anzugeben. Löst die PageIndexChanged Ereignisse und PageIndexChanging aus.
"Update" Aktualisiert den aktuellen Datensatz in der Datenquelle. Löst die ItemUpdated Ereignisse und ItemUpdating aus.

Obwohl das ItemCommand Ereignis ausgelöst wird, wenn auf eine schaltfläche geklickt wird, die in der vorherigen Tabelle aufgeführt ist, wird empfohlen, die in der Tabelle für den Vorgang aufgeführten Ereignisse zu behandeln.

Beim Erstellen eines FormViewCommandEventHandler-Delegaten bestimmen Sie die Methode für die Ereignisbehandlung. Um dem Ereignishandler das Ereignis zuzuordnen, fügen Sie dem Ereignis eine Instanz des Delegaten hinzu. Der Ereignishandler wird bei jedem Eintreten des Ereignisses aufgerufen, sofern der Delegat nicht entfernt wird. Weitere Informationen zu Ereignishandlerdelegaten finden Sie unter Behandeln und Auslösen von Ereignissen.
