Benutzerdefinierter Editor für modale Dialogfelder zur Adapterkonfiguration
Der Code für den benutzerdefinierten Editor zeigt einen Von der System.Drawing.Design.UITypeEditor-Klasse abgeleiteten Editor an, der ein modales Popupdialogfeld zum Eingeben eines Kennworts anzeigt. Die Außerkraftsetzung der GetEditStyle-Methode gibt UIEditorEditStyle.Modal zurück, um ein modales Formularuntersteuerelement anzugeben. Die Dienstmethode ShowDialog verwaltet das mit CreatePassword erstellte Steuerelement. ShowDialog gibt ein DialogResult zurück, das auf die übliche Weise behandelt wird (z. B. eine switch-Anweisung), wobei nur der Wert der Groß-/Kleinschreibung DialogResult.OK geändert wird.
Der folgende Code stellt die Klassendefinition für den benutzerdefinierten modalen Editor dar:
