Comentários
Usando o conjunto de controles Web Parts, você pode ativar dois controles de servidor formar uma conexão e compartilhar dados, com um controle que atua sistema autônomo o provedor de dados e Outros atuando sistema autônomo consumidor de dados. Os dois controles podem ser WebPart controles ou qualquer Outros tipo de controle de servidor, fornecido que eles foram projetados para manipular conexões e residem em um WebPartZoneBase zona.
Para obter mais informações sobre o ConnectionsZone e controles Web Parts, consulte ASP.NET Web Parts Controls.
Exemplo
O exemplo de código a seguir demonstra como usar o ConnectionsZone controle em uma página da Web, declarativamente. Dentro do elemento, um número de propriedades está conjunto declarativamente. Outras propriedades na zona de conexões são definidas por meio de programação no script seção da página.
Para obter as definições para o controle de usuário e o controle personalizado que é definido com @ Registerdiretivas, consulte "Exemplo" na classe visão geral do ConnectionsZone.
