How do you approach this? only one boolean field on a list`

gvolkov

say there is a list form. a shipment methods for example. i added a field called default (boolean). how do i make it so there can only be one default? meaning when there is one checked, and someone checks another one, that first one becomes FALSE.

garak

you must develop this on code.

FIELDDEFAULT - OnValidate()
IF FIELDDEFAULT THEN BEGIN
  ShipMethod.RESET;
  ShipMethod.SETFILTER(Code,'<>%1',Code);
  ShipMethod.MODIFYALL(FIELDDEFAULT,FALSE);
END ELSE BEGIN
  ERROR('!! Stop !! Now, there is no DEFAULT Shipment Mehod');
END;
