I have a custom list that has been linked to 2 content types. So let's say the NewForm.aspx uses content type #1 (the default) to create the list items. Is it be possible to create a custom EditForm.aspx to edit the list item using content type #2?
I used SharePoint designer 2013 to create a custom edit form and linked the edit form to use content type #2. Then when I test the new edit button SharePoint throws an error. So my gut feeling is that you can only edit the list item with the content type that was used creating it. I hope I am wrong..
