Hi Jim,
Jim Dorrance wrote : " I put on page 0 and set visible/invisible." Yes, I noticed that when putting the widget on page 0 it works. Unfortunately I want to use widgets a lot In this example I have a form with 9 pages, with on some pages more than 5 widgets This will create a lot of mess when putting all on page 0 and set it visible / invisible I am hoping for some other solution It looks like a subform on a page is only recognized when this page has been fully loaded and drawn?
