Esempio

Nell'esempio di codice seguente viene creato un ListView controllo con tre oggetti specificati e tre ListViewItemListViewItem.ListViewSubItem oggetti specificati per ogni elemento. L'esempio crea ColumnHeader anche oggetti per visualizzare gli elementi secondari nella visualizzazione dei dettagli. Due ImageList oggetti vengono creati anche nell'esempio di codice per fornire immagini per gli ListViewItem oggetti. Questi ImageList oggetti vengono aggiunti alle LargeImageList proprietà e SmallImageList . Nell'esempio vengono usate le proprietà seguenti nella creazione del ListView controllo:

• View

• LabelEdit

• AllowColumnReorder

• CheckBoxes

• FullRowSelect

• GridLines

• Sorting

È necessario aggiungere il codice a un Form e chiamare il metodo creato nell'esempio dal costruttore o da un altro metodo nel modulo. L'esempio richiede che le immagini denominate MySmallImage1, MySmallImage2, MyLargeImage1e MyLargeImage2 si trovino nella directory radice dell'unità C.

Esempio

Nell'esempio di codice seguente viene creato un modulo che contiene un ListView controllo che ordina manualmente gli elementi quando viene fatto clic su una colonna nel ListView controllo. L'esempio definisce una classe denominata ListViewItemComparer che implementa l'interfaccia che esegue il System.Collections.IComparerListViewItem confronto. Nell'esempio viene creata un'istanza di ListViewItemComparer e viene usata per impostare la ListViewItemSorter proprietà del ListView controllo. La Sort chiamata al metodo nel ColumnClick gestore eventi usa i metodi definiti in ListViewItemComparer per eseguire il tipo di elementi, in base alla colonna su cui viene fatto clic.
