CustomCallbackEventArgs Class

Provides data for the WebChartControl.CustomCallback event.

Namespace:DevExpress.XtraCharts.Web
Assembly:DevExpress.XtraCharts.v18.2.Web.dll

Expanded Syntax

Expanded 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 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.
