ObjectList.CommandStyle 屬性

定義

取得或設定物件清單命令所使用的樣式。 這個 API 已經過時。 如需如何開發 ASP.NET 行動應用程式的資訊,請參閱 mobile Apps & Sites with ASP.NET

public:
 property System::Web::UI::MobileControls::Style ^ CommandStyle { System::Web::UI::MobileControls::Style ^ get(); void set(System::Web::UI::MobileControls::Style ^ value); };
public System.Web.UI.MobileControls.Style CommandStyle { get; set; }
member this.CommandStyle : System.Web.UI.MobileControls.Style with get, set
Public Property CommandStyle As Style

屬性值

物件清單命令所使用的樣式。

範例

下列程式代碼範例示範如何使用 CommandStyle 屬性來設定 樣式 ObjectList ,並使用宣告式 DeviceSpecific 區段來指定不同裝置的不同 CommandStyle 設定。

注意

下列程式代碼範例會使用單一檔案程式代碼模型,如果直接複製到程式代碼後置檔案,可能無法正常運作。 此程式代碼範例必須複製到具有.aspx擴展名的空白文本檔。 如需詳細資訊,請參閱 ASP.NET Web Forms Page Code Model

備註

如果以程式設計方式設定此屬性,除非在每個要求上動態設定屬性,否則不會保存此屬性。 如果屬性是以宣告方式設定,則會在每個要求上設定 屬性。 沒有預設值。

因為不同的裝置有不同的樣式需求。 您可能需要屬性的數 DeviceSpecificCommandStyle 設定。
