È possibile utilizzare gli stili predefiniti forniti da Microsoft per la visualizzazione elenco con alcune modifiche per rendere lo sfondo degli elementi selezionati così com'è. A causa del limite di spazio, sto includendo le modifiche apportate allo stile ListViewItem originale per riferimento immediato:

Non credo che questa funzionalità sia incorporata, sfortunatamente. Probabilmente dovrai implementare un 'GridView' personalizzato. –
Se lo hai implementato tu stesso, un link github sarebbe davvero, davvero bello. ;) –
@ Dänu Ci sto pensando. Penso che fare qualcosa tra l'attuale e questa implementazione sia sufficiente. Alla fine, ne parlerò e lo metto su Github ogni volta che è pronto. –
