Esempio

Nell'esempio di codice seguente viene illustrato come usare la ListView funzionalità di tiling. Nell'esempio la visualizzazione riquadro visualizza elementi che rappresentano libri. Ogni elemento viene visualizzato come riquadro contenente un'icona di un libro, il titolo, l'autore e l'anno di pubblicazione. Per il funzionamento del codice di esempio, è necessario includere un file di icona denominato Book.ico nella stessa directory dell'esempio. Per visualizzare la visualizzazione riquadro senza icone, aggiungere commenti alle righe relative all'oggetto ImageList .

Commenti

Questa proprietà controlla le dimensioni dei riquadri quando la View proprietà è impostata su View.Tile. L'impostazione di questa proprietà è utile per impedire il wrapping della riga quando il testo dell'elemento secondario è troppo lungo da visualizzare in una singola riga.
