TFieldDataLink.LayoutChanged procedure
LayoutChanged- called if layout is changed: tests validity of
field then calls
OnLayoutChange event handler.Declaration
procedure LayoutChanged; overrideDescription
LayoutChanged is an overridden procedure called when the field
binding in the linked dataset for a data-aware Control has been changed.
LayoutChanged calls the ValidateField method to ensure that the Field is
valid / up-to-date, or set to
Nil when the FieldName does not exist in
the linked dataset. If the Field is assigned (not
Nil), the
EditingChanged and RecordChanged methods are called.
LayoutChanged does not call the inherited method.
LayoutChanged is used primarily in the implementation of methods in TCustomDBGrid and descendent classes.
