Summary

Specifies a text to display when the lookup value is empty.

Pascal

 propertyDisplayEmpty: string;

Description

Use DisplayEmpty to display a string when an empty lookup value is selected. Property EmptyValue specifies which value is the empty value.
Also when the drop-down list of the control is shown, an extra fixed row is displayed with the string DisplayEmpty as text. When the user selects this row the lookup value is set to EmptyValue (or to Null if EmptyValue is the empty string and EmptyStrIsNull is True).
Set DisplayEmpty to an empty string (the default) to disable this feature.
