While working with forms, a split form can be a very useful view because you simultaneously get two views of the form that are connected to the same data source. This demo shows you how to create a split form view where you can use the datasheet part of the form to quickly locate a record and the form portion to view or modify the record. You will also learn how to enhance and customize a split form view to suit your needs.
