To clear a DBLookupComboBox, you should call the "Clear" method of the data field, associated with the control. As there is no way to do this from the control itself, you may add a button / speed button next to the control:

procedure TForm1.SpeedButton1Click (...)
begin
Table1Field1.Clear;
end;

Here I assume that you have a Table component with a field named Field1 and that DataField property of your DBLookupComboBox component is attached to it.

Have fun,
