I am using the Telerik Report Server and I need to create a ReportBook at runtime. Could somebody please provide an example or more guidance on how to accomplish this?
Could you please elaborate further on the scenario at hand?
If you need to create a report book at runtime and then display it in a report viewer, you may do so by implementing a custom IReportSourceResolver where you create the report book and then return it in the Resolve method. The following articles should help you in how you may implement such functionality:
If you need to do anything else outside of a report viewer, you can pretty much use the same code except that you do not need a custom resolver in such a case.
If you need to upload the created report book to your report server, you may again use the Report Server API Client to do so - Report Server REST API v2.
