Crystal Reports™ 8.5 Developer's Guide

How to Get Additional Information
The Search and Select Expert buttons on the top right part of the viewer are
over-ridden, allowing you to specify default criteria to search for.
Alternatively, the default search and select experts can also be displayed.
Simple Demo
This simple demonstration presents an introduction to the Report Designer. Many
of the basic methods used in manipulating and creating reports are discussed in the
code comments. This is a good starting point if you are unfamiliar with the RDC.
Unbound fields
This application shows you how to create a report template using the new
Unbound Fields capability. It also shows you how to bind the fields at runtime to
adatasourcethatyoualsocreateatruntime.
In this sample, there are five unbound fields created in the report. Notice that there
is no data source added to the report at design time at all—the data source is
created and added to the report at runtime.
You can also use Unbound fields in formulas, although this sample does not
demonstrate this use.
Unbound fields give you great flexibility in your programming. They even allow
you to create a single report template that can be bound to a variety of data sources
at runtime in response to user input. This enables you to create a wide range of
custom reports all from a single template. See the Pro Athlete Salaries application
for a demonstration of this capability.
Viewer
This simple application shows you how you can create your own Report Viewer
toolbar and manipulate the ActiveX viewer using your own custom buttons.
Viewer Runtime options
This application demonstrates the many ways you can manipulate the Report
Viewer at runtime. It also shows you how to implement the use of the Select Expert
and the Search Expert in the Viewer.
All of the check boxes on the main form correspond to viewer properties that you
can change at runtime. In this sample, there are more than 21 viewer properties
that are manipulated. Note that to enable the Select Expert and Search Expert, you
must reference the Crystal Select Expert OLE control module and you must place
the Select Expert Control on the form.
The Select/Search Expert is essentially invisible on the form and is located
immediately to the left of the About Sample Command Button in this sample.
