TDataLink Class

TDataLink is a helper class used by data-aware objects to coordinate the actions of TDataSource and TDataSet, and to respond to data events.

Pascal
TDataLink = class(TPersistent);
C++
class TDataLink : public TPersistent;

DB

Use TDataLink or one of its descendants in any data-aware object that implements a DataSource property to represent its link to a dataset or that needs to respond to data events. 

The constructor of the data-aware object should call the constructor of TDataLink, and initialize any relevant properties. The data-aware object can then link to a TDataSource by using the DataSource property of the TDataLink. 

Data-aware objects that link to a single field in a dataset should use a TFieldDataLink instead.
