Syntaxe déclarative du contrôle serveur Web ProxyWebPartManager
Fournit un moyen aux développeurs de déclarer des connexions statiques dans une page de contenu lorsqu'un contrôle WebPartManager a été déclaré dans la page maître associée à la page de contenu.

Notes
Le contrôle ProxyWebPartManager existe pour le scénario particulier de déclaration des connexions statiques dans les pages de contenu lorsqu'un contrôle WebPartManager a déjà été déclaré dans une page maître.
Pour plus d'informations sur les contrôles ProxyWebPartManager et WebPart, consultez Contrôles WebPart ASP.NET.
Exemple
L'exemple de code suivant illustre comment utiliser la classe ProxyWebPartManager pour déclarer des connexions statiques sur les pages de contenu dans une application qui utilise des pages maîtres.
Pour les définitions du contrôle utilisateur et le contrôle personnalisé défini avec des directives @ Register et la page maître référencée avec l'attribut MasterPageFile dans la directive @ Page, consultez l'« Exemple » dans la vue d'ensemble de la classe pour ProxyWebPartManager.
