I'm developing an WPF app that imports trdx file, serializes to a report object, set an ObjectDataSource and generate (using RenderReport method) to pptx file.
The trdx file contains a subreport with the same DataSource but different DataMember. The DataMember of the subreport get an input from the a report parameter (=Parameters.Param1.Value). The subreport parameter filled by the main report (Param1 =Fields.Id).
For example, for each order in the report, the subreport get its ID as parameter and returns all its order details.
In the generated report (pptx) I see all the reports data but the subreport data is empty. How should I set the DataSource, DataMember and Paramerters of the subreport correctly?
