public event ASPxClientCustomDataCallbackEventHandler CustomDataCallback
Public Event CustomDataCallback As ASPxClientCustomDataCallbackEventHandler
The CustomDataCallback event allows any desired server-side processing to be performed, and any resulting required information to be passed to the client for further processing (if needed).
After the CustomDataCallback event has been processed on the server side, a result can be passed back to the client via the CallbackEventArgs.Result property. To receive the result on the client, handle the ASPxClientDashboard.CustomDataCallback event.
