The navigation functionality in
Crystal Reports lets you move
to other report object(s) in the same report, or to object(s) in another
report—with a specified data context. This navigation is available only in the
DHTML viewers (zero-client, server-side viewers). Its advantage is that you can
link directly from one object to another; the viewer passes the required data
context so you go to the object and data that is relevant.
Report Parts use this navigation
functionality when linking between Report Part objects. The key difference
between Report Part navigation and regular (page) navigation is that, when
navigating with Report Parts (using the Report Part Viewer), you see only the
objects identified as Report Parts. In regular navigation (using the page
viewers or the Advanced DHTML Viewer), you go to the identified object(s), but
you see the entire page.
