CustomCallbackEventArgs is the data class for the following events:

• WebChartControl.CustomCallback

Remarks

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

Note that performing a custom callback results in chart redrawing. That is why there is no Result property exposed by the CustomCallbackEventArgs class.
