Description
UpdateData us used to perform the actions needed to update a
linked dataset using the current selection in the control.
In TDBRadioGroup, this involves assigning the content from the
Value property to the field for the linked dataset. UpdateData
uses the internal TFieldDataLink instance for the control to
access the Field for the linked dataset. No actions are performed
when the field in the TFieldDataLink instance has not been assigned.
UpdateData is assigned to the OnUpdateData event handler in the
TFieldDataLink instance for the data-aware control.
