After you have added a recordset to a page, and have created a navigation bar, you must apply
individual server behaviors to each navigation element. For example, a typical recordset
navigation bar contains representations of the following links matched to the appropriate
behavior:
Navigation link
Go to first page
Go to previous page
Go to next page
Go to last page

Displaying and hiding regions based on recordset results
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).
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.
The Show Region server behaviors are:
•
Show If Recordset Is Empty
•
Show If Recordset Is Not Empty
•
Show If First Page
•
Show If Not First Page
•
Show If Last Page
•
Show If Not Last Page
To learn how to apply the Show Region server behaviors, see

Displaying multiple recordset results
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.
