Report Part Viewer
The Report Part Viewer is a viewer that lets you display Report Parts without
the rest of the report page. You can integrate this viewer into web applications
so that your users see only specific report objects without having to see the
rest of the report.
For the most part, you set up the Report Part hyperlinks in the Report
Designer, but you take advantage of their functionality in the report viewers.
What is navigation?
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. In this last case, the other report must be managed in
BusinessObjects Enterprise, or must be part of a stand-alone Report
Application Server environment. 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.
Setting up navigation
Navigation (page or Report Part) is set up on the Hyperlink tab of the Format
Editor dialog box.
In the DHTML Viewer Only area of the Hyperlink tab, you can select one of
two options:
Report Part Drilldown
The Report Part Drilldown option is available for summary fields, group
charts and maps, and fields in your report’s group header or group footer.
This option is relevant only to Report Parts; regular navigation (using the
page view) drills down by default. For more information, see “Report Part-
specific navigation” on page 400.
Another Report Object
You can use the Another Report Object option for both Report Part and
page navigation. This option lets you specify the destination object(s) you
want to navigate to and the data context to pass.
