Commenti

DataGridColumnStyle utilizza un PropertyDescriptor oggetto per determinare il tipo di dati visualizzati nella colonna . Per restituire un PropertyDescriptorCollectionoggetto , utilizzare il GetItemProperties metodo della BindingManagerBase classe .

Utilizzare questo costruttore per creare un formato personalizzato per i dati visualizzati.

DataGridColumnStyle utilizza un PropertyDescriptor oggetto per determinare il tipo di dati visualizzati nella colonna . Per restituire un PropertyDescriptorCollectionoggetto , utilizzare il GetItemProperties metodo della BindingManagerBase classe .

Per altre informazioni sulla formattazione dei caratteri, vedere Formattazione di tipi e stringhe di formato di data e ora personalizzate.
