構文
解説
DocumentList コントロールは、ネイティブ Windows CE DocList コントロールのマネージ実装を提供します。DocList コントロールは、たとえば、Microsoft® Pocket Word や Microsoft® Pocket Excel を起動すると表示されます。このコントロールには、次の機能が用意されています。
DocumentList は、FileDialog のようにダイアログ ボックス全体ではなく、1 つのコントロールです。DocumentList コントロールを使用すると、ファイルを選択する UI にカスタム メニューや他のコントロールを含めることができます。
DocumentList は、これを配置するフォームと同じ幅にする必要があります。長さは必要な長さに設定できます。
DocumentList は、マイ ドキュメントの階層にある選択したフォルダのファイルだけを表示します。
Panel に含める DocumentList コントロールを作成するコード例を次に示します。
