Fires when a round trip to the server has been initiated by a call to the client ASPxClientCardView.PerformCallback method.
public event ASPxCardViewCustomCallbackEventHandler CustomCallback
Public Event CustomCallback As ASPxCardViewCustomCallbackEventHandler
The CustomCallback event's data class is ASPxCardViewCustomCallbackEventArgs. The following properties provide information specific to this event:
|Parameters||Gets a string that contains specific information (if any) passed from the client side. Inherited from ASPxGridCustomCallbackEventArgs.|
The CustomCallback event allows any desired server-side processing to be performed in response to a call to the client ASPxClientCardView.PerformCallback method.
Use the ASPxGridCustomCallbackEventArgs.Parameters property to get the information passed from the client side.
Don't export the ASPxCardView's content during callbacks, because ASP.NET does not support sending binary content during a callback.
The example below uses two ASPxCardView controls to display master-detail data.
