Internally, the component uses temporal TFDQuery and TFDTable components to handle data queries. The data provider properties and events are assigned to these components. If you want to assign additional properties to them, use OnDataSetCreated event.

In addition to the default query processing, you can provide another DataSet component in OnCreateDataSet event. This DataSet is not necessary needed to be TFDQuery or TFDTable.
