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 DeviceSpecific 個 CommandStyle 設定。
