DataGrid.FooterStyle プロパティ
アセンブリ: System.Web (system.web.dll 内)

DataGrid コントロールのフッター セクションのスタイル プロパティを格納している TableItemStyle オブジェクト。既定値は空の TableItemStyle オブジェクトです。

このプロパティを使用して、DataGrid コントロールのフッターのカスタム スタイルを指定します。調整できる共通スタイル属性には、前景色、背景色、フォント、セル内の内容の配置などがあります。異なるスタイルを指定すると、DataGrid コントロールの外観が詳細に設定されます。
DataGrid コントロールの FooterStyle プロパティは、ControlStyle プロパティのスタイル設定を継承します。たとえば、ControlStyle プロパティに赤いフォントを指定した場合は、FooterStyle プロパティにも赤いフォントが設定されます。これにより、単一のスタイル プロパティを設定するだけで、コントロールの全体的な外観に統一感を持たせることができます。FooterStyle プロパティを設定して、継承されたスタイル設定をオーバーライドできます。たとえば、FooterStyle プロパティに青いフォントを指定して、ControlStyle プロパティで指定した赤いフォントをオーバーライドできます。
フッター セクションのカスタム スタイルを指定するには、<FooterStyle> タグを DataGrid コントロールの開始タグと終了タグの間に配置します。その後、<FooterStyle> の開始タグ内にスタイル属性のリストを記述できます。
