ProxyWebPartManager Web 伺服器控制項宣告式語法

更新：2007 年 11 月

為開發人員提供了當 WebPartManager 控制項已在內容頁面的關聯主版頁面 (Master Page) 中宣告時在內容頁面中宣告靜態連接的方法。

 <asp:ProxyWebPartManager     EnableTheming="True|False"     EnableViewState="True|False"     ID="string"     OnDataBinding="DataBinding event handler"     OnDisposed="Disposed event handler"     OnInit="Init event handler"     OnLoad="Load event handler"     OnPreRender="PreRender event handler"     OnUnload="Unload event handler"     runat="server"     SkinID="string"     Visible="True|False" >         <StaticConnections>                 <asp:WebPartConnection                     ConsumerConnectionPointID="string"                     ConsumerID="string"                     ID="string"                     ProviderConnectionPointID="string"                     ProviderID="string">                             <asp:RowToFieldTransformer                                 FieldName="string"/>                             <asp:RowToParametersTransformer                                 ConsumerFieldNames="string"                                 ProviderFieldNames="string"/>                 </asp:WebPartConnection>         </StaticConnections> </asp:ProxyWebPartManager>

備註

當 WebPartManager 控制項已經在主版頁面中宣告時，則 ProxyWebPartManager 控制項會存在於內容頁面中宣告靜態連接的特定案例。

如需 ProxyWebPartManager 和 Web 組件控制項的詳細資訊，請參閱 ASP.NET Web 組件控制項。

範例

下列程式碼範例示範如何使用 ProxyWebPartManager 類別來宣告使用主版頁面之應用程式中內容頁面上的靜態連接。

如需使用者控制項和以 @ Register 指示詞定義之自訂控制項的定義及用 @ Page 指示詞中 MasterPageFile 屬性參考的主版頁面，請參閱 ProxyWebPartManager 之類別概觀中的「範例」。
