La DataGridViewImageColumn classe è un tipo specializzato della DataGridViewColumn classe usata per ospitare logicamente le celle che visualizzano immagini. Un oggetto DataGridViewImageColumn ha un oggetto associato DataGridViewImageCell in ogni DataGridViewRow oggetto che lo interseca. Ogni cella è in grado di contenere un Image oggetto o , Icona seconda del valore della DataGridViewImageCell.ValueIsIcon proprietà. La visualizzazione delle icone è utile per gestire le immagini con trasparenza.
Per impostazione predefinita, le celle vuote visualizzano un elemento grafico di errore predefinito. Per evitare che questo elemento grafico venga visualizzato per i valori delle celle uguale a null o DBNull.Value, impostare la DataGridViewCellStyle.NullValue proprietà dell'oggetto stile cella restituito dalla DefaultCellStyle proprietà su null prima di aggiungere righe al controllo. Ciò non influisce sulla riga per i nuovi record, tuttavia. Per evitare che l'elemento grafico di errore venga visualizzato nella riga per nuovi record quando il valore della proprietà del controllo è , è necessario impostare in modo esplicito il valore della cella su in un gestore per l'evento di controllo AllowUserToAddRowsRowsAdded o impostare la proprietà colonna CellTemplate su un'istanza di un DataGridViewImageCelltipo derivato con una proprietà sottoposto a null override DefaultNewRowValue che restituisce null.true
La modalità di ordinamento predefinita per questo tipo di colonna è NotSortable.
Note per gli eredi
Quando si deriva da DataGridViewImageColumn e si aggiungono nuove proprietà alla classe derivata, assicurarsi di eseguire l'override del Clone() metodo per copiare le nuove proprietà durante le operazioni di clonazione. È anche necessario chiamare il metodo della Clone() classe base in modo che le proprietà della classe di base vengano copiate nella nuova cella.
