Description
Generates an OnDataRequest event on the specified provider component.
Datasnap.Win.MtsRdm.TMtsDataModule.AS DataRequest inherits from Datasnap.DataBkr.TRemoteDataModule.AS_DataRequest. All content below this line refers to Datasnap.DataBkr.TRemoteDataModule.AS_DataRequest.
Generates an OnDataRequest event on the specified provider component.
Use AS_DataRequest to invoke an OnDataRequest event handler of the provider named by ProviderName. AS_DataRequest is provided to allow application developers to customize the communication between a client application and a provider component. There is no predefined meaning for the Data parameter or the return value (Delphi) or the AS_DataRequest _result parameter (C++), which is returned to the caller.
Note: Applications can only call the protected AS_DataRequest method using the TRemoteDataModule interface.
