CustomCallbackEventHandler Delegate

Represents a method that will handle the WebChartControl.CustomCallback event.

Namespace:DevExpress.XtraCharts.Web
Assembly:DevExpress.XtraCharts.v17.2.Web.dll

Expanded Syntax

Parameters

sender
Type: Object
The event source. This parameter identifies the WebChartControl which raised the event.
e
Type: CustomCallbackEventArgs
A CustomCallbackEventArgs object which contains event data.

Expanded Remarks

When creating a CustomCallbackEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
