The WebPartManager controle atua sistema autônomo o centralizar de hub ou um controle de um aplicativo Web Parts. Deve haver um — e somente um — a instância do WebPartManager controle em cada página que usa controles de Web Parts e deve ser colocado antes de qualquer controle de zona são colocados. sistema autônomo ocorre com a maioria dos aspectos de aplicativos de Web Parts, a WebPartManager controle funciona somente com usuários autenticados. Além disso, sua funcionalidade funciona quase que totalmente com os controles de servidor que residem nas zonas de Web Parts que herdam o WebZone classe. Controles de servidor que residem em uma página fora de nessas zonas podem ter muito pouca funcionalidade Web Parts ou interação com o WebPartManager controle.

Para obter mais informações sobre o WebPartManager e controles Web Parts, consulte ASP.NET Web Parts Controls.

Exemplo

O exemplo de código a seguir demonstra como usar o WebPartManager controle declarativamente em um cenário de Web Parts usando o Calendar controle. A página da Web permite que um usuário entrar no modo de edição para editar determinados aspectos do Calendar controle. The Alternar escopo botão alterna a página ao usuário ou o escopo de personalização compartilhado. The modo de edição and Procurar de modo botões cada comutador a página no modo de exibição apropriado. Observe que no <script> seção do arquivo, dois dos métodos que lidam com o uso de eventos de marca a Personalization propriedade para acessar membros útil do objeto base. Especificamente, esses métodos usam o ToggleScope método e o Scope propriedade no objeto que é acessado através do Personalization propriedade.

No exemplo de código seja executado, você também deve ativar um ou mais usuários personalizar páginas no escopo compartilhado. Para fazer isso, adicione uma entrada para o arquivo Web.config no webParts elemento (ASP.NET Settings esquema).
