使用例
3 つの ListViewItem オブジェクトが指定され、各項目に 3 つずつ ListViewItem.ListViewSubItem オブジェクトが指定されている ListView コントロールを作成するコード例を次に示します。この例では、ColumnHeader オブジェクトを作成して、詳細ビューにサブ項目を表示します。また、2 つの ImageList オブジェクトも作成して、ListViewItem オブジェクトのイメージを用意します。これらの ImageList オブジェクトは、LargeImageList プロパティおよび SmallImageList プロパティに追加されます。この例では、ListView コントロールの作成時に、次のプロパティを使用します。
このコードを Form に追加し、この例で作成されているメソッドを、フォームのコンストラクタまたはフォーム上のその他のメソッド内で呼び出す必要があります。この例では、MySmallImage1、MySmallImage2、MyLargeImage1、MyLargeImage2 という名前の各イメージが C ドライブのルート ディレクトリに保存されている必要があります。
