Exemples

L’exemple de code suivant crée un formulaire qui contient un ListView contrôle qui trie manuellement les éléments lorsqu’une colonne du ListView contrôle est cliquée. L’exemple définit une classe appelée ListViewItemComparer qui implémente l’interface System.Collections.IComparer qui effectue la ListViewItem comparaison. L’exemple crée une instance de et l’utilise ListViewItemComparer pour définir la ListViewItemSorter propriété du ListView contrôle. L’appel Sort de méthode dans le ColumnClick gestionnaire d’événements utilise les méthodes définies dans ListViewItemComparer pour effectuer le type d’éléments, en fonction de la colonne sur laquelle on clique.

Remarques

Vous pouvez utiliser cette version de la Add méthode pour ajouter un existant ColumnHeader à la collection. Si vous souhaitez créer un nouveau ColumnHeader au moment où vous l’ajoutez à la collection, vous pouvez utiliser l’autre version de la Add méthode.

Lorsque des en-têtes de colonne sont ajoutés, ils sont ajoutés à la fin de la collection. Pour insérer un en-tête de colonne dans la collection à une position spécifique, utilisez la Insert méthode . Pour ajouter un ensemble d’en-têtes de colonne à la collection en une seule opération, utilisez la AddRange méthode .

Exemples

L’exemple de code suivant crée un ListView contrôle avec trois ListViewItem objets spécifiés et trois ListViewItem.ListViewSubItem objets spécifiés pour chaque élément. L’exemple crée ColumnHeader également des objets pour afficher les sous-éléments en mode Détails. Deux ImageList objets sont également créés dans l’exemple de code pour fournir des images pour les ListViewItem objets. Ces ImageList objets sont ajoutés aux LargeImageList propriétés et SmallImageList . L’exemple utilise les propriétés suivantes pour créer le ListView contrôle :

• View

• LabelEdit

• AllowColumnReorder

• CheckBoxes

• FullRowSelect

• GridLines

• Sorting

Cet exemple nécessite que vous ayez ajouté le code à un Form et que vous appeliez la méthode créée dans l’exemple à partir du constructeur ou d’une autre méthode sur le formulaire. L’exemple exige également que les images nommées MySmallImage1, MySmallImage2, MyLargeImage1et MyLargeImage2 se trouvent dans le répertoire racine du lecteur C.

Remarques

Vous pouvez utiliser cette version de la Add méthode pour créer un nouveau ColumnHeader à ajouter à la collection. Le texte du nouveau ColumnHeader ajouté au contrôle est basé sur le text paramètre . Cette version de la Add méthode vous permet également de spécifier la largeur de la colonne et l’alignement du texte dans l’en-tête de colonne. Si vous avez un existant ColumnHeader que vous souhaitez ajouter à la collection, utilisez la version de la Add méthode qui accepte un ColumnHeader comme paramètre.

Lorsque des en-têtes de colonne sont ajoutés, ils sont ajoutés à la fin de la collection. Pour insérer un en-tête de colonne dans la collection à une position spécifique, utilisez la Insert méthode . Pour ajouter un ensemble d’en-têtes de colonne à la collection en une seule opération, utilisez la AddRange méthode .
