I have a detail band with potentially a lot of text fields in it. It can get too wide to fit on a page. The result is that it just runs off the edge of the page and you can't see it all. I'd like the detail band to wrap around to another line. Is there any way to do this?
My detail band is built dynamically in the code and the number of fields can vary. I tried manually placing the overflowing fields lower in the band by setting their y values, but then if the text in the fields overflows into two lines, my height calculations are off and the results get really messed up.
So is there any way to constrain the band to fit on the page?
Unfortunatelly, the strech types in jasper only works between bands, not within the band.
You can't (even manualy) create a jrxml which will cause a lower element in a band be correctly possitioned when an upper element overflows.
You will need to create more than one detail band. In iReport, you use 'Add another detail band' (on the detail band context-menu). Dynamically, it would look something like:
JRDesignSection detailSection = (JRDesignSection)design.getDetailSection();
JRDesignBand detail2 = new JRDesignBand();
detailSection.addBand(detail2);
Perhaps on your reportElement for each field in the band you need to set the attribute stretchType="RelativeToTallestObject".
<reportElement stretchType="RelativeToTallestObject" ...>
I'm pretty sure that's what works for me.

I'm working on a report in Jasper for Java. I put the table header in the title band, the content in the details band and the summary part of table in the summary band (these are all different tables). The same Dataset is used in all three tables.
Here is the scheme of bands
However, when I print it to pdf (via Java REST service) this gap appears between tables. Picture
Tell me please how to remove it? Any ideas appreciated.
Stretch the row height to full title band.
Also adjust the height of the band using below code snippet:
<band height="<your_couple_of_lines_of_text_height>">
<printWhenExpression><![CDATA[$V{PAGE_NUMBER} < 2]]></printWhenExpression>
the_conditional_header_content_here
</band>
I have a JasperReport file with the basic header/detail/footer bands. In my Details, I have a Column Header row in a Grid Layout and a Detail Row, also in a GridLayout. I'm having a few issues with this Detail section. I have 3 columns that I'm hiding with an expression using printWhenExpression=$P{Exp1}. This works to hide the field, but the rest of the columns in the detail section don't adjust to this. So I'm left with a giant blank column in the middle of my detail section.
I'm coming from Crystal Reports where I could just suppress fields and the CR would adjust widths as necessary. I can't seem to find anything to do the same with JasperReports, which doesn't make much sense since I would expect a GridLayout to try and fill up the space as needed. So is there any way to have a table/grid like layout that will adjust column widths to fill the available space when a field is hidden.
All Works fine but, rows margin do not cover all height. as shown in attached these two pictures.
How I am doing: I put rectangle in detail band, than sub report and other fields. on all fields, sub-report and rectangle i also apply stretchType="RelativeToTallestObject and isStretchWithOverflow="true" for warping up the text which works fine. I am facing this problem still unresolved.
As per my understanding: sub-Report fields are also stretchType="RelativeToTallestObject but didn't detect or get stretched of its main-report column. while if sub-report need extra space it will show properly. I have tried almost every thing available in iReport-Designer.
Drop figures. Use borders, preferably via report styles.
Data that we get from data source is not shown in detail band. But make some processing for each of records and processing result is shown in Group footer.
So I cannot remove detail band, as it is the only place for processing individual record. But I want to hide it, making invisible.
If I use printWhenExpression, it causes not only hiding the detail band but also no processing is done for records.
What I want is just hide(making invisible and do not make any blank) but processing is done for each iteration. If possible, may I know how to do it.
Remove all elements (static text, text field and so on) from detail band and set height = 0 px at detail band property
You can either set its height to 0 px in the properties section on the right side
OR
You can Right click > delete band. (The band can later be added back if needed).
I have a JasperReports report build with iReport. I have the normal Detail band but below i have a textField named observations there is sometimes the Observations textField is empty or NULL. I have put both inner components namely textfields, lines into frames something like.
I also set using Print When Expression the below frame the one who holds the Observations textField to appear only when there is data on it this is working very good but the space holds by the frame is still on the Detail and we are losing some space and it's kind annoyng to see this blank space.
Is it possible for the report to "delete" the idle space hold it by the hidden frame?
My report's design:
The generated result (PDF file):
I don't think it's possible to alter the height of a band depending on its content but you can actually have multiple detail bands. So add a new one, move your observation text field into it and set the print when expression of the second band.
