Comentários

O verbo de desconexão, como usado com um ConnectionsZone controle, é um verbo de nível de zona que aparece na interface do usuário da conexão como parte da exibição na qual os usuários gerenciam uma conexão existente entre dois controles.The disconnect verb, as used with a ConnectionsZone control, is a zone-level verb that appears in the connection user interface (UI) as part of the view in which users manage an existing connection between two controls. Depois que os usuários clicarem no WebPart verbo conectar no menu de verbos de um controle, e a interface de usuário de conexão aparecer, se já houver uma conexão entre dois controles, o verbo de desconexão aparecerá ativado próximo à parte inferior da interface do usuário.After users have clicked the WebPart connect verb on the verbs menu of a control, and the connection UI appears, if there is already a connection between two controls, the disconnect verb appears activated near the bottom of the UI.

Use a DisconnectVerb propriedade para obter uma referência ao objeto correspondente WebPartVerb na interface do usuário.Use the DisconnectVerb property to get a reference to the corresponding WebPartVerb object in the UI. Embora a própria propriedade seja somente leitura, depois de ter uma referência ao verbo, você pode alterar seus valores de propriedade conforme necessário.Although the property itself is read-only, after you have a reference to the verb, you can change its property values as needed.

Você pode definir os valores de Propriedade do verbo de desconexão declarativamente, declarando o <disconnectverb> elemento entre as marcas de abertura e de fechamento de um <asp:connectionszone> elemento.You can set the property values of the disconnect verb declaratively, by declaring the <disconnectverb> element between the opening and closing tags of an <asp:connectionszone> element. As propriedades do verbo também podem ser definidas declarativamente dentro da marca de abertura do <asp:connectionszone> elemento, adicionando um atributo no formulário Property-Subproperty , em que Subproperty é uma propriedade do WebPartVerb objeto (por exemplo, DisconnectVerb-Text ).The properties of the verb can also be set declaratively within the opening tag of the <asp:connectionszone> element, by adding an attribute in the form Property-Subproperty, where Subproperty is a property of the WebPartVerb object (for example, DisconnectVerb-Text). Você também pode definir as propriedades programaticamente no formulário Property.Subproperty (por exemplo, DisconnectVerb.Text ).You can also set the properties programmatically in the form Property.Subproperty (for example, DisconnectVerb.Text).
