subreport

问题 I am printing a details subreport that gets printed let's say 5 times on the overall report, for 5 query results. I compute some stuff for it with my code, and so I use BeforePrint event on an XRTable widget that I have in that subreport. So far so good. What I don't like is that when the BeforePrint executes for that table for the first time and I change its cells' text to something, that this renders on all subsequent instances of this report and table being printed. Now, obviously, since

问题 I have made one main report containing a few subreports. At the end I would like to compare some figures from the different parts of the report and also make some calculations with numbers received from the different parts. Does anybody know a way to get values from the subreport into the main report? All calculations e.g. aggregates that will be made at the end refer only to the dataset for the main part and the other subreports have their own datasets, fetched from other tables. 回答1: I must

问题 Let's say I have three lists: Departments, Divisions, and Groups. A Department is made up of Divisions, which in turn is made up of Groups. The Divisions have the Department ID as a foreign key. The Groups have the Division ID as a foreign key. I'd like to produce a report that looks like this: Department 1 Division 1A Group 1A-i Group 1A-ii Group 1A-iii Division 1B Group 1B-i Group 1B-ii Group 1B-iii Division 1C Group 1C-i Group 1C-ii Group 1C-iii Department 2 Division 2A Group 2A-i Group 2A

问题 I try to use subreport using JasperSoft Studio but I get the exception below. It cannot find the subreport file although it is there. net.sf.jasperreports.engine.JRException:Resource not found at: D:\\JASPERREPORTS\\MyReports Below is the configuration of main report <?xml version="1.0" encoding="UTF-8"?> <!-- Created with Jaspersoft Studio version last--> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi

问题 I am so close to having this work, I am trying to directly embed one jasper subreport into the main report xml of the other. You'd think this would be easy, but I can't find a single example on doing it. Everyone seems to use files or resources or whatever. I have one report working straight from a string and I want it to contain it's subreport. Anyone? Syntax? Thanks! 回答1: The only way I know of to do this with JasperReports is to use a separate .jrxml file for the subreport, and include it

问题 I'm creating a 'master' report in SSRS 2008 that collaborates other reports about a person. Sometimes not all of the other reports are relevant and as such return nothing. I'd like to be able to exclude this from the master report so it does not leave a blank page. I'm aware of the 'no-rows-message' feature, but a whole page with simply "Not applicable for this person" is hardly the best solution! Essentially I'm looking for a way to determine if a subreport is 'empty' and use that in a

问题 I am able to have a report with multiple subreports export to Excel with each subreport on a separate tab/sheet using the info here (placing each subreport within a Rectangle control and setting its PageBreak property to "Start"). I hoped that setting the Rectangles' PageName property would set the sheet names to what I assign there, but no - they are simply " Sheet 2 ", " Sheet 3 ", etc. So how can I assign a specific value to the sheet names so that those values are used when the SSRS

问题 I am following this tutorial to create my reports using iReport . I have already created a couple of reports using the guidelines mentioned. But in a new report, when I set the DataSource of the ListComponent Jasper reports the following error to me: The method subDataSource(String) is undefined for the type JRDataSource value = ((net.sf.jasperreports.engine.JRDataSource)parameter_REPORT_DATA_SOURCE.getValue()).subDataSource("/items/invoices"); //$JR_EXPR_ID=11$ I tried to look up in the docs
