public class CustomCallbackEventArgs : EventArgs
Public Class CustomCallbackEventArgs Inherits EventArgs
The WebChartControl.CustomCallback event is raised when a round trip to the server has been initiated. This occurs when the client ASPxClientWebChartControl.PerformCallback method is called.
The CustomCallbackEventArgs class provides the CustomCallbackEventArgs.Parameter property. This property specifies a string that contains specific information passed from the client side.
Note that performing a custom callback results in chart redrawing. That is why there is no Result property exposed by the CustomCallbackEventArgs class.
