Invisible Tabs and buttons worked a treat.... thanks
I have been playing around with the idea you have of invisible tabs with the same portal repeated in varying sort oders. It suits my purpose, especially when I only need two tabs. Sorted:
Portal row sorted TimeStampCreated: Descending
Portal row sorted TimeStampCreated: Ascending
The 'Add' portal record works well. It adds the new portal record and row to the portal on both tabs, obviously becasue they are just a copy of the same portal. However, I have one question:
How do you delete a portal row (and the record itself). You can not use 'Delete Portal Row" becuase the protal row in the active tab will delete along with the record, but the portal row in the other tab will only delete the field contents of the portal and not the portal row itself. It will remain with no values......?
I found this (http://www.nightwing.com.au/FileMaker/resources/PortalSorting.pdf) to be very simple, easy and elegant. No hidden tabs. It's a truly dynamic re-sort field. Took me about 5 minutes to put into place and it can easily be changed.
