TdxBarLookupCombo.OnKeyValueChange Event

Occurs when the value of the KeyValue property changes.

Declaration

property OnKeyValueChange: TNotifyEvent read; write;

Remarks

The KeyValue property changes every time an end-user selects a new row in a dropdown list. Unlike the OnKeyValueChange, the OnChange event occurs when the contents of the combo box editor change. If the old and new items in the list have the same field values (their ListFieldIndex values are equal), the OnChange event is not fired.
