例

次のコード例は、コントロールの初期化を ListView 示しています。 この例では、オブジェクトを作成 ColumnHeader し、列ヘッダーの Text、 TextAlign および プロパティを Width 設定します。 この例では、 に項目とサブ項目も追加します ListView。 この例を実行するには、次のコードをフォームに貼り付け、フォームのコンストラクターまたはLoadイベント ハンドラーから メソッドを呼び出PopulateListViewします。

注釈

このプロパティを使用すると、各 ColumnHeaderに表示されるテキストに異なるテキスト配置設定を指定できます。

注意

基になるコントロールの制限により、このプロパティはコントロールの ListView 最初の列に影響を及ぼすので、常に左に配置されます。 .NET Framework 2.0 でこの制限を回避するには、イベントをListView.DrawColumnHeader処理し、列ヘッダーを自分で描画します。
