TabPage.GetTabPageOfComponent メソッド
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim comp As Object Dim returnValue As TabPage returnValue = TabPage.GetTabPageOfComponent(comp)
戻り値
指定されたオブジェクトが格納されている TabPage。オブジェクトが見つからない場合は null 参照 (Visual Basic では Nothing)。

それぞれが 1 つの Button コンポーネントを含む、2 つの TabPage オブジェクトのある TabControl を作成するコード例を次に示します。この例では、パラメータ button2 が GetTabPageOfComponent メソッドに渡されています。このメソッドは、button2 が含まれる TabPage を取得します。正しいタブ ページが取得されたことを検証するために、SelectedIndex プロパティは、button2 を含む TabPage を、現在選択されているタブ ページに設定します。
この例では、System.Drawing 名前空間と System.Windows.Forms 名前空間を使用します。
