Data source connectivity

Crystal Reports can report off virtually any kind of data source, including persistent sources such as databases and XML files, and runtime sources such as object collections. Using the ReportClientDocument object model, you can programmatically access and change the connection information to these data sources for the report file.

This section explains how to use the DatabaseController class to interact with the data sources in a report.

Classes used for connecting to data sources

• CrystalDecisions.ReportAppServer.Controllers.DatabaseController

Retrieves current data source connections, sets new data source connections for the tables in a report, and adds runtime data sources.

• CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfos

Contains ConnectionInfo objects representing each connection in the report to a specific data source.

• CrystalDecisions.ReportAppServer.DataDefModel.Tables

Contains Table objects representing each table in the report. Each table has a ConnectionInfo object representing a valid data source connection.

• Data source connection properties
• To log onto a report database
