#Remarks
If the AllowFocusedCard property is set to false
, the focused card feature is disabled. In this instance, the ASPxCardView.FocusedCardIndex property’s value is always -1 and the ASPxCardView.FocusedCardChanged event isn’t raised. The style settings used to paint the focused card are not used. To identify the card currently being edited, use the ASPxCardView.EditingCardVisibleIndex property.
