How to setup a jasper report with any length of height? - jasper-reports

Say that a jasper report should be generated to a thermal printer. The detail band may be 1 row or 200+ rows.
How to generate jasper report with its height fitting to the row count instead of printing white-spaces in the end?

Set the pageHeight to just one row and then use
isIgnorePagination="true"
When isIgnorePagination is true the report will be generated in a
single page.
Hence, if just one row, it will have the height of one row, if more rows it will not create new pages but generate a continues layout.
For example see: http://jasperreports.sourceforge.net/sample.reference/nopagebreak/

Jaspser Reports Detail Dyanmic Column Width

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.

Detail band resize dynamically vertically when textfield is NULL

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.

Summary band subreport displays only last value

I am displaying list of string values in detail band of the report , it works fine. And i want to draw 5 graphs in summary band. I tried in summary band it took all the values and generated report but summary band height was limitted. so i drawed only three graphs in that space. I moved to sub report to draw all the 5 graphs.
i passed values to subreport through parameter map. I got all the 5 graphs, but the graph is drawed using the last value passed to the subreport. I want to draw the graphs with all the values passed to it. How to to this ?
Try to use the same datasource as you're using in your main report. Should work fine.
You can achieve this using the property $P{REPORT_DATA_SOURCE} in your subreport data source expression, but don't forget to set the connection type as well.

How to increase Height and Width of Crosstab Cell in Crystal report dynamically according to text size?

How to increase Height and Width of Crosstab Cells in Crystal report dynamically according to text size. I have already checked the "Can grow" property to true for individual cells but have no change.
I am new in crystal reports. Please help me.
Don't think you can. You only get to set the height and width of one crosstab cell at design time. You may have to consider a different approach that 'simulates' different column widths in the crosstab.

Crystal Reports columns in details band, change direction

here's what I am trying to accomplish:
I'm working on a single page report using Crystal Reports 2008, and at the bottom right corner of a page, I have a subreport that puts 1/2" square bitmap images in details-band columns that might print one image, or up to five horizontally. Right now, they print left to right.
What I would like to do is have them start from the right side of the subreport, i.e. the first image in the right corner, and additional ones print to the left. Is there a way to make this happen? I've tried changing Section Expert > Details/Layout > Printing Direction between the options "Across then Down", and "Down and Across", no luck with that.
thanks in advance
I was able to get this approach to work:
create a subreport that contains the image in the Details section. Add a suppression formula to the Details section that reads: RecordNumber<>1;
hide all sections but the Details section
size the subreport to fit the image (1/2" width)
move the subreport to the right edge of the relevant section
link the main report to the subreport
right click the subreport and save it to your Desktop
insert a subreport and choose the one that you just saved
size it to fit the image and move it adjacent to the first one
edit the subreport, hide the non-Details section, change the Details' suppression formula to RecordNumber<>2
repeat steps 5-9 for the remaining 3 images (changing the suppression formula)
The idea is that each subreport retrieves all of the image row for the related row in main report. you suppress all rows in each subreport but the one that you want to display.
