Jak włączyć widok kafelkowy w kontrolce ListView formularzy systemu Windows

Funkcja widoku kafelka kontrolki ListView pozwala uzyskać równowagę wizualną między informacjami graficznymi a tekstowymi. Informacje tekstowe wyświetlane dla elementu w widoku kafelkowym są takie same jak informacje kolumn zdefiniowane dla widoku szczegółowego. Widok kafelkowy działa razem z funkcjami grupowania lub wstawiania znaczników w kontrolce ListView.

Widok kafelkowy używa ikony 32 x 32 piksele i kilku linii tekstu, jak pokazano na przykładach poniżej.

Widok kafelkowy

Aby włączyć widok kafelka, ustaw właściwość View na Tile. Rozmiar kafelków można dostosować, ustawiając właściwość TileSize i liczbę wierszy tekstu wyświetlanych na kafelku, dostosowując kolekcję Columns.

Aby ustawić widok kafelek programowo

1. Użyj wyliczenia View kontrolki ListView.

   ListView1.View = View.Tile  
   

   listView1.View = View.Tile;  
   

Przykład

Poniższy kompletny przykład kodu przedstawia widok Kafelki z kafelkami zmodyfikowanymi w celu wyświetlenia trzech wierszy tekstu. Rozmiar kafelka został dostosowany, aby zapobiec zawijaniu linii.
