DataGrid のスタイルとテンプレート

更新 : 2011 年 4 月

このトピックでは、DataGrid コントロールのスタイルおよびテンプレートについて説明します。 既定の ControlTemplate に変更を加えることで、コントロールに独自の外観を設定できます。 詳細については、「ControlTemplate の作成による既存のコントロールの外観のカスタマイズ」を参照してください。

DataGrid のパーツ

次の表は、DataGrid コントロールの名前付きパーツの一覧です。

DataGrid の ControlTemplate を作成するときに、テンプレートの ScrollViewer 内に ItemsPresenter が含まれる場合があります。 ItemsPresenter により、DataGrid の各項目が表示されます。また、ScrollViewer により、コントロール内でスクロールできるようになります。 ItemsPresenter が ScrollViewer の直接の子でない場合は、ItemsPresenter に ItemsPresenter という名前を付ける必要があります。

DataGrid の既定のテンプレートには、ScrollViewer コントロールが含まれています。 ScrollViewer で定義されたパーツの詳細については、「ScrollViewer のスタイルとテンプレート」を参照してください。
