A Report Book is a class inheriting Telerik.Reporting.ReportBook. The ReportBook.ReportSources collection allows you to add reports of different formats (XML, TRDX and TRDP files, run-time instances or classes inheriting Telerik.Reporting.Report) into the book, where the Reporting Engine knows how to process the separate reports based on the type of the used Report Source for adding them.
The Report Book online demo is available also in the local Examples installed by default under ..Telerik\Reporting R2 2017\Examples . An example how to create a ReportBook instance at run-time can be found in How to: Create a Report Book at run-time.
