The main goal of a report book is combining different reports into one document for the purposes of printing them at once or exporting them to a single file. Reports are displayed in the order they were added to the report book. This sample Report Book combines four reports from the Telerik Reporting samples: DashBoard, ProductSales, ProductCatalog, ProductLineSales. Note, how each report page settings are preserved thus allowing you to easily print/export them without any further modifications. Each report in the book is processed as a stand alone item and the result is compiled in an aggregate document. There is no additional performance cost outside of the performance costs for each individual report the report book holds in itself.
