Comentários
O ProxyWebPartManager existe um controle para o determinado cenário de declarar conexões estáticas no conteúdo de páginas quando um WebPartManager controle já foi declarado em um página mestra.
Para obter mais informações sobre o ProxyWebPartManager e Web Parts de controles, consulte ASP.NET Web Parts Controls.
Exemplo
O exemplo de código a seguir demonstra como usar o ProxyWebPartManager classe para declarar conexões estáticas em páginas de conteúdo em um aplicativo que usa páginas mestras.
Para as definições para o controle de usuário e o controle personalizado que é definido com @ Register diretivas e a página mestra referenciado com o MasterPageFile o atributo na @ Página diretiva, consulte "Exemplo" na visão geral de classe para ProxyWebPartManager.
