The Event Attendance grid allows you to see the details of the attendees for a specific event. You can view and update attendee information and check attendees in and out for the event. With the Actions menu you can also export data, send emails and texts, print badges and name tags, batch update records, and pick a raffle winner. You can navigate to the Event Attendance grid from Workspace > Events > Event Attendance.
There are also event attendance details available on in the constituent's record under their Event Attendance tab.
