Sends a callback to the server and generates the server-side ASPxCardView.CustomDataCallback event.
GetValuesOnCustomCallback(args: string, onCallback: ASPxClientCardViewValuesCallback): void
A string value that is any information that needs to be sent to the server-side ASPxCardView.CustomDataCallback event.
Use the GetValuesOnCustomCallback method if you need to asynchronously go to the server and perform some server-side processing using AJAX-based callback technology. You can pass the required information which can be collected on the client side as a string of arguments via the GetValuesOnCustomCallback method's args parameter.
The GetValuesOnCustomCallback method posts back to the server using the callback technology and generates a server-side ASPxCardView.CustomDataCallback event. The method's args argument is passed to the ASPxCardView.CustomDataCallback event's handler as the ASPxGridCustomCallbackEventArgs.Parameters property. So, the necessary server-side actions can be performed in the event's handler based upon the values of the arguments which can be obtained by parsing the passed information string.
After the callback is processed in the ASPxCardView.CustomDataCallback event's handler, the resulting information can be passed back to the client side's function specified by the onCallback parameter. This information is specified by the event's ASPxGridCustomDataCallbackEventArgs.Result property.
