Microsoft® SharePoint® Designer 2010 Unleashed

Field Limit on Custom Forms

There is a limit of 70 fields (67 fields plus one attachment field, one created by field and one modified by field) on custom forms. The limit can be overcome by instead customizing a list form with an InfoPath 2010 form (see Chapter 26). For further details, see the related thread on the SharePoint MSDN forums, at http://social.msdn.microsoft.com/Forums/en-US/sharepoint2010customization/thread/88a27ba6-7134-4ae3-b1d2-1179c5b2f26e.
