Description

Occurs when a provider calls its DataRequest method.

Write an OnDataRequest event handler to do custom processing of data. OnDataRequest has no built-in use. Instead, it allows developers to augment the IAppServer interface so that clients in a multi-tiered application can communicate directly with an individual provider.

If an application does not provide an OnDataRequest event handler, calls to DataRequest return NULL.

Note: To provide the same sort of custom processing on the client side, use an automation method on the connection component.

OnDataRequest is of type Datasnap.Provider.TDataRequestEvent
