次のコード例ではListView 、3つListViewItemのオブジェクトを指定ListViewItem.ListViewSubItemし、各項目に対して3つのオブジェクトを指定して、コントロールを作成します。The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.ListViewSubItem objects specified for each item. また、この例ColumnHeaderでは、詳細ビューにサブ項目を表示するオブジェクトも作成します。The example also creates ColumnHeader objects to display the subitems in details view. またImageListListViewItemオブジェクトのイメージを提供するために、コード例に2つのオブジェクトが作成されます。Two ImageList objects are also created in the code example to provide images for the ListViewItem objects. これらImageListのオブジェクトは、 LargeImageListプロパティとSmallImageListプロパティに追加されます。These ImageList objects are added to the LargeImageList and SmallImageList properties. この例では、コントロールをListView作成するときに、次のプロパティを使用します。The example uses the following properties in creating the ListView control:

この例では、 Formにコードを追加し、この例で作成したメソッドをコンストラクターまたはフォームの別のメソッドから呼び出す必要があります。This example requires that you have added the code to a Form and call the method created in the example from the constructor or another method on the form. また、この例MySmallImage1ではMyLargeImage1、、 MySmallImage2、、およびMyLargeImage2という名前のイメージが、C ドライブのルートディレクトリにあることが必要です。The example also requires that images named MySmallImage1, MySmallImage2, MyLargeImage1, and MyLargeImage2 are located in the root directory of drive C.

注釈

プロパティがに設定さAllowColumnReorderれてViewいる場合をDetails除き、プロパティの値を設定しても効果はありません。Setting the value of the AllowColumnReorder property has no effect unless the View property is set to Details. このプロパティを使用すると、ユーザーが実行時にコントロールの列の位置を変更できるようになります。You can use this property to allow users to reposition columns in the control at run time. プロパティがにtrue設定されている場合、ユーザーは、アプリケーション内でのニーズを満たすように、項目とそのサブ項目を表示するようにコントロールの列を配置できます。 AllowColumnReorderWhen the AllowColumnReorder property is set to true, users can position the columns in the control to display the item and its subitems in a way that meets their needs within your application.
