TDBLookupListBox.IsUnbound function

Declaration

function IsUnbound: Boolean

Function result

Description

IsUnbound is a Boolean function which indicates if the control is being used in the "unbound" mode - where either the DataField or DataSource are not assigned for the control. This mode allows the control to synchronize the lookup dataset to the current item selection in the control, but does not post the control value to its linked dataset.

IsUnBound is used in the DoSelectionChange method to determine if the UpdateData method needs to be performed.
