Posted 26 March 2020, 6:05 am ESTI've been experimenting with Drill-Through Page reports. It seems they do not work when the reports as set as Embedded Resources within the assembly. Clicking on a control in the report that activates the secondary report produces the following exception:
System.Exception: Report to execute not found or failed: PageReportDetail ---> System.NullReferenceException: Object reference not set to an instance of an object.
