Some controls in the Koda are meaningless alone and should be “attached” to another control. For instance, this is Updown and Imagelist controls.
How to attach control (on example of Updown to Input):
create an Updown control on the form;
create Input control;
in Input control select “Updown” prooperty - it have dropdown list where you will see previously created Updown control(s);
choose control from list - you will see that now Updown is tightly aligned to Input.
now Koda will generate updown code related to it's Input
