Member of TFieldDataLinkprotectedIn unit DBCtrls

FocusControl gives the input focus to the data-aware control in the class instance.

Description

FocusControl is an overridden procedure used to give input focus to the data-aware Control for the class instance.

AField is a reference to the TField which defines the field for the data-aware control. AField must be assigned, and point to the Field used in the class instance. No actions are performed in the method if either condition is not met.

FocusControl can be used for any Control descended from TWinControl where its CanFocus value is True; the SetFocus method in the Control is called to receive the input focus.
