Description

Informs the TDBLookupControl of changes in the Active property of its DataSource.

Applications cannot call the ActiveChanged procedure directly. Changes in the Active property trigger this procedure. When the Active property becomes true, ActiveChanged causes the TDBLookupControl object to re-acquire its DataField property. This ensures that the lookup control is working with the correct field component.
