Curious to know how you can create custom data and limit its use to only one event?  Right now, to have custom registration data for an event we do this:

1. Create custom data group for the data - assign it to participant: Attendee
2. Add fields and as needed
3. Create profile for the same group of data
4. Add custom data fields from that group we created
5. Adding that to CiviEvent

That works fine (if it is the right procedure?).  But, if I pull up a contact and edit their event registration, i see ALL of the custom data groups for all of the events, not just for the one event they registered for.  So, I can't save the information unless I fill in the mandatory fields for each of the data groups.

I am thinking that the work around is to create custom participant types for each event?  (e.g. Attendee-Conference-DC-08) so that only that data shows up for that event?  It seems onerous, but is that the best way to do it?

Currently, custom data groups which extend the "Participant" record are either "used for" for "all participants", or for participants with a specific participant role ("Speaker", "Volunteer", etc.).

As you've noted, you can filter these more flexibly for online registration forms based on the Profile(s) you assign them to (and then include in a given Event Reg form). However, you can't filter them for offline registration by Event. Your work-around below will work. However, if you can at least categorize them a bit more generally by role + event type, rather than simply by event - that might be a bit better.

EXAMPLE: If all your Golf Tournament type events require the same set of custom fields, you could have a role of "Attendee - Tournament" (or something like that).

You can add more profiles to a page IF you make the relevant code changes. However not sure if this is a good path to go, since it introduces code changes and hence u fork (which means u need to merge for future upgrades etc). The schema allows multiple profiles, so no schema changes are needed.

In case u do want to implement it, some of the files u need to change are:

CRM/Event/Form/ManageEvent/Registration.php (to collect all profiles u want displayed)

CRM/Event/Form/Registration.php
CRM/Event/Form/Registration/*.php

This has come up a few times in the past, i suspect we'll think  about adding this capability in a future 2.x version.
