Dreamweaver includes a set of server behaviors that let you show or hide a region based on the
results returned by a recordset. For example, in a page using “Previous” and “Next” record
links to navigate a results page, you can specify that the “Previous” records link be shown on
all results pages except the first (which has no previous results), and that the “Next” records
link be shown on all pages except the last (which has no next results).

link be shown on all pages except the last (which has no next results).
You can also specify that a region be displayed or hidden based on whether the recordset is
empty or not. If a recordset is empty (for example, no records were found matching the
query), you can display a message informing the user that no records were returned. This is
especially useful when creating search pages that rely on user input search terms to run queries
against. Similarly, you can display an error message if there is a problem connecting to a
database, or if a user’s user name and password do not match those recognized by the server.

■
Show If Not Last Page

The Repeat Region server behavior lets you display multiple records from a recordset within a
page. Any dynamic data selection can be turned into a repeated region. However, the most
common regions are a table, a table row, or a series of table rows.
