DrawListViewSubItemEventArgs.Bounds プロパティ

public:
 property System::Drawing::Rectangle Bounds { System::Drawing::Rectangle get(); };

public System.Drawing.Rectangle Bounds { get; }

member this.Bounds : System.Drawing.Rectangle

Public ReadOnly Property Bounds As Rectangle

プロパティ値

描画する Rectangle の境界を表す ListViewItem.ListViewSubItem。

例

次のコード例では、コントロールのカスタム描画を Bounds 提供するアプリケーションで プロパティを使用する方法を ListView 示します。 この例では、 イベントのハンドラー ListView.DrawSubItem によって、負の値を持つサブ項目のサブ項目テキスト値とテキストと背景の両方が描画されます。

完全な例については、概要のリファレンス トピックを DrawListViewSubItemEventArgs 参照してください。
