I have developed a custom ASPX page (a SharePoint application page) which is used as a replacement for the default EditForm. I need to have some fields available for editing (so, not all as the default one is providing) and I need additional functionality to happen once the user clicks the Save button on the form.
Miming the functionality from the EditForm for the fields has proven to be quite a lot of work. I have two multi-choice people and group fields and one managed metadata field.
Is there a way to quickly, or more efficiently, generate the standard behavior for those fields and to append additional functionality to the Save action? Thanks.
