In oracle application framework OAF NavigationBar is used to navigate to the next or previous set of records.
You might have mostly saw NavigationBar attached with the table or advance table.
Suppose you have run a BC4J VO query that retrieved more than 10 records to be displayed in a table.
Then a NavigationBar will appear at the top and bottom of the table. By using the NavigationBar link you can display the next 10 records, which are retrieved from the query.
NavigationBar can also be seen in the Hgrid region, in case we expand a node and the child retrieved are more than the record limit, that time we have to use NavigationBar link.
Note: No need to declare NavigationBar functionality explicitely.
