问题 I have report that uses a subreport, but since the subreport is stored in a database table as BLOB , I cannot give its path (url) in the *.jrxml file. Is there a way to add a *.jasper file loaded from the database ( BLOB or InputStream ) as a subreport. 回答1: I figured it out. Add a list component In the list's dataset fetch the field you keep your subreport as a BLOB, lets call it REPORT_DATA . Set REPORT_DATA field's type to InputStream . Add the subreport inside the list. Set "Subreport

问题 I have a clean Jasper report that calls a subreport with no filter. In that subreport I show all the Json data (10 rows), and if I see the preview it works: Subreport preview. The problem is when I call the subreport from the main (and clean) report. It only has in the detail the professionalName and the subreport. It should show the professionalName and all the subReport (all 10 rows each time), but it's not the case. It only shows the current row, and I'm sure it's because the main report

问题 using SSRS 2008 R2 and wondering, if is possible to generate sub-report for each value selected in multi-valued parameter? Lets imagine you have multi-valued parameter "parameterA" with four values selected (Value1, Value2, Value3 and Value4). I'd like to generate sub-report for each of these values (passing the value as single parameter). Sure, I can change the procedure to handle multi-valued parameter, but because of performance and caching I really don't want to. Thanks for any advice.

问题 I'm using Report Viewer at C# in WinForms. I have 3 database tables: Equipament, Sector and History, I also have 3 Report.rdlc, The MAIN is the ReportEquipament and the other two subreport are ReportSector and ReportHistory. I already know how to fill the ReportSector, what I want to do is to pass the idSector from the ReportSector, so I can call a procedure at the SQL Server database and search all the History with this Sector ID, and show the data at the ReportHistory. I have no idea on how
