In the forms that I "Save As Class" I don't use a DataEnvironment. I open all files in the forms Load Event. Actually I never use the form's DataEnvironment. Anything else you can think of? I'd hate to have to dump the formset model. >This is usually related to a problem with one of the contained >controls not being able to bind to it's data source. Since you >saved the form as a class you basically hosed the DataEnvironment >the form had.
