TemplateContainer 類別

衍生自 Panel 類別並由 ASP.NET 用於包含 DeviceSpecificChoice 樣板。

命名空間： System.Web.UI.MobileControls
組件： System.Web.Mobile (在 system.web.mobile.dll 中)

語法

'宣告
Public Class TemplateContainer
    Inherits Panel
    Implements INamingContainer
'用途
Dim instance As TemplateContainer

public class TemplateContainer : Panel, INamingContainer

public ref class TemplateContainer : public Panel, INamingContainer

public class TemplateContainer extends Panel implements INamingContainer

public class TemplateContainer extends Panel implements INamingContainer

備註

若行動控制項透過裝置樣板來提供樣板化呈現功能，則必須在型別為 TemplateContainer 的各個控制項中，建立每個樣板的執行個體。如果資料繫結 (Data Binding) 運算式位於樣板的控制項中，運算式 Container 變數的型別一定是 TemplateContainer。

範例

在下列程式碼中，示範了如何使用 TemplateContainer 物件在行動表單的 DeviceSpecific 物件內建立樣板。

注意事項
以下程式碼範例使用單一檔案程式碼模型，如果直接複製到程式碼後置 (Code-Behind) 檔案即可能無法作用。這個程式碼範例必須複製到副檔名為 .aspx 的空白文字檔。如需 Web Form 程式碼模型的詳細資訊，請參閱 ASP.NET Web 網頁程式碼模型。
