MVCxClientChart.BeginCallback Event

Occurs when a callback for server-side processing is initiated.


BeginCallback: ASPxClientEvent<MVCxClientBeginCallbackEventHandler<MVCxClientChart>>

Event Data

The BeginCallback event's data class is MVCxClientBeginCallbackEventArgs. The following properties provide information specific to this event:

Property Description
command Gets a command name that identifies which client action forced a callback to occur. Inherited from ASPxClientBeginCallbackEventArgs.
customArgs Gets an object containing specific information (if any, as name/value pairs) that should be passed as a request parameter from the client to the server side for further processing.


The BeginCallback and ASPxClientWebChartControl.EndCallback events can be used to perform specific client-side actions (for example, to display and hide an explanatory text or picture) while a callback is being processed on the server side.

By handling the BeginCallback event, you can pass any required information from the client to the server via the MVCxClientBeginCallbackEventArgs.customArgs property.
