Fires after the focused card has been changed.
public event EventHandler FocusedCardChanged
Public Event FocusedCardChanged As EventHandler
The FocusedCardChanged event's data class is EventArgs.
The FocusedCardChanged event is raised when an end-user moves focus from one card to another or after the ASPxCardView.FocusedCardIndex property’s value has been changed in code.
If the ASPxCardViewBehaviorSettings.ProcessFocusedCardChangedOnServer property is set to false, the ASPxClientCardView.FocusedCardChanged event is handled on the client side without a callback to the server. Setting this property to true indicates that the final processing of the event should be performed on the server side, and so a round trip to the server is required. During such a round trip the corresponding server-side FocusedCardChanged event is fired, which if handled, allows any desired server-side action to be performed.
The example below demonstrates how to show ASPxCardView’s detail data. You can also refer to the following DevExpress Support Center example: T272616: ASPxCardView - How to display master-detail data using two ASPxCardView controls.
