One detail that you've probably added to a number of forms is a split
view. A split view usually involves dividing your form horizontally
with a datasheet view on one half and a columnar view on the other. In
previous versions of Access, creating a split view usually left
developers with a splitting headache, trying to synchronize the main
form with a sub form. Luckily, Access 2007 makes this task much, much
easier. All you have to do is set the DefaultView property to
SplitForm. You even have a choice of how you want to position the two
form types. In Design View, you can use the SplitFormOrientation
property to move the datasheet view to the left, bottom, or right of
the form.
