Participant to user mapping

If I want to create a list of users are associated with a participant in runtime (to populate a dropdown list), how would I query the system to return to me a list of user names in the way I would see them on the “participants” tab in design time? in essence, assuming a REVIEWER participant, “tell me who all the REVIEWERs are.”

Apologies for the late reply.

You can use a group. Assign only that group to the participant REVIEWER.
And then do an SQL Query retrieving all users from that group to populate the dropdown list.

Best regards,
Eddy.
