ObjectList.CommandStyle プロパティ

定義

名前空間:

System.Web.UI.MobileControls

アセンブリ:

System.Web.Mobile.dll

オブジェクト リスト コマンドに使用するスタイルを取得または設定します。 この API は、互換性のために残されています。 ASP.NET モバイル アプリケーションを開発する方法については、「mobile Apps & Sites with ASP.NET」を参照してください。

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

プロパティ値

Style

オブジェクト リスト コマンドに使用するスタイル。

例

次のコード例では、 プロパティをCommandStyle使用して宣言型DeviceSpecificセクションを使用してのスタイルをObjectList設定し、デバイスごとに異なるCommandStyle設定を指定する方法を示します。

注釈

このプロパティがプログラムによって設定されている場合、各要求で プロパティが動的に設定されていない限り、このプロパティは保持されません。 プロパティが宣言によって設定されている場合、各要求で プロパティが設定されます。 既定値はありません。

デバイスによってスタイルの要件が異なるためです。 プロパティのいくつかの DeviceSpecific 設定が CommandStyle 必要な場合があります。
