I am using one master reports with some static data and three subreports. Subreports can repeat zero to many times and are approximately half page long. I have put each subreport in a separate table and each such table on a separate detail band.
My problem is that each subreport always starts on a new page. They each consist of multiple detail bands that all have "Split allowed" set to true
Maybe "When No Data - No Pages" property may do what you want.

I am new to JasperReports, basically I want to put a subreport in a mainreport
The problem is that I put the sub report in the Detail band, so when I query a database that has multiple data the subreport will always repeat itself multiple times when I output the report to a pdf. I want a report that does not repeat itself regardless of how many data I have in the database that i connect with
I have searched the Internet and the solutions is to add
new Boolean($V{REPORT_COUNT}.intValue()==1)
in the print when expression attribute of the subreport, that does solve a part of my problem due to the fact that now my subreport only prints once but it still leaves some blank pages after my subreport is displayed
So I assume it is still repeating itself but just doesn't print the data because of the expression that I added , people say that the nature of the detail band is supposed to work that way and that I shouldn't put the subreport in the detail band, but if I put it in some other band I get this error:
Error filling print... Subreport overflowed on a band that does not support overflow.
The error above will happen if I have a lot of data to the extent that it may take up more than a page.
How do remove those blank pages? If I am ask to not put it in a detail band then what should I do? or what solution are there?
The Detail band will be generated as many times as the number of records you have in your main dataSet(populated by the top-level query).
If you want to keep the subreport in the Detail band, which is normal by the way, you can do one of these things:
either have a dummy query that returns only one record, so that the Detail band generates only once. Then, pass the report connection to your subreport. You may have done that already. This way you can run your query independently of the main report.
or leave the report as-is and add your printWhen expression ($V{REPORT_COUNT}.intValue()==1) directly on the Detail band, not on the subreport. Please note that this is just an ugly hack that may affect the report performance. Your main query still returns a lot of data that you don't use so you should consider the other options.
If you can move the subreport out of the Detail band, place it in a band that allows overflow like Title or Summary band. Then:
have your main dataSet's query empty so that no Detail band gets generated
set whenNoDataType="AllSectionsNoDetail" at the report level(in the <jasperReport> tag) so that all the other sections except the Detail get generated
exactly as in the first option above, pass the report connection to your subreport and work from there

The subreport has two Detail bands, the first is "Title" and the second is another subreport.
These bands are divided from each other on two pages.
I tried a lot of properties without result as "ignore pagination" and "split allowed"
My question is: How can I force ireport not to split my subreport on two pages ?
I have some screenshots:
The master report:
The subreport:
Another subreport:
The resulting pdf file looks like this:
Instead of using two bands in the principle subreport, put the title and the second subreport into the same band. Then set the splitType for that single band to "Prevent". That way, the title and data will be kept together and the split will happen before the title if the data will not fit on the page.
Edit - Preventing the title from repeating:
Putting the title into the detail band will make it repeat with each set of data. To prevent this, change the printWhenExpression to $V{REPORT_COUNT} == 1. This will cause it to be printed only once, for the first record, and not for each subsequent loop through the datasource.
I have a report with two subreports. The first subreport is very short, the second one is quite long. I would like the exported spreadsheet to have a single sheet/tab for each of these two subreports.
In the main report's layout, the two subreports separated by a page break.
When I export (or just view the html in the browser), the page break appears after the first subreport, but the second one is then chopped into several more pages (because its very long).
Now I could make the main report a million pixels in height, but that would be an ugly hack making the first subreport appear with data in the first 10 rows and followed by thousands of empty rows.
How can I fix this?
(It is driving me mad.)
the report has a property called "Ignore Pagination" (iReport 4.0.2). If checked, it will print the whole document as a single page.
My Requirement is to show two sub reports in a Report. What I am doing is, I have created two sub-reports and put that into a report.
But the issue is that, both the sub reports are growing (i.e. their height is not static as the number of records are variable). I just want the second sub=report to appear after the end of first sub-report. How can I achieve the same?
You can use the option "Position Type" by selecting "Float" as the value. So based on the first reports size the second one will be adjusted.

You could put the second subreport inside the first subreport, in the page footer. The footer moves down when the detail band grows, so the subreport should always end up underneath the content of the first subreport.

Try to add detail band as many as your subreport to your main report (You can right click the detail band and choose "Add another detail band"). And place each subreport on every detail band that you make.
Detail band have ability to shrink and grow depend on your data row and it will fit nicely to your report.
