L’exemple de code suivant crée un ListView contrôle avec trois ListViewItem objets spécifiés et trois ListViewItem.ListViewSubItem objets spécifiés pour chaque élément.The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.ListViewSubItem objects specified for each item. L’exemple crée également ColumnHeader objets à afficher des sous-éléments en mode Détails.The example also creates ColumnHeader objects to display the subitems in details view. Deux ImageList objets sont également créés dans l’exemple de code pour fournir des images pour les ListViewItem objets.Two ImageList objects are also created in the code example to provide images for the ListViewItem objects. Ces ImageList objets sont ajoutés à la LargeImageList et SmallImageList propriétés.These ImageList objects are added to the LargeImageList and SmallImageList properties. L’exemple utilise les propriétés suivantes pour créer le ListView contrôle :The example uses the following properties in creating the ListView control:

Cet exemple nécessite que vous avez ajouté le code à un Form et appelez la méthode créée dans l’exemple à partir du constructeur ou une autre méthode sur le formulaire.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. L’exemple suppose également que les images nommées MySmallImage1, MySmallImage2, MyLargeImage1, et MyLargeImage2 se trouvent dans le répertoire racine du lecteur C.The example also requires that images named MySmallImage1, MySmallImage2, MyLargeImage1, and MyLargeImage2 are located in the root directory of drive C.
