iReport - display Page x / y only if number of pages is > 1

[Nicolas Micoud]

Hi all,

I'm struggling with iReport (4.6.0) trying to create a report for an invoice that will display "Page x/y" (x is current page and y number of pages) when the report has more than one page.

ATM, I have 2 fields :
#1 : "Page " + String.valueOf($V{PAGE_NUMBER}) + "/ "
#2 : String.valueOf($V{PAGE_NUMBER})

And i use different evaluation times to get values (Now for current page, Report for total)

But i can't find a way to display them only when the report has more than one page.

Any hint ?

Thanks,

Nicolas

not sure it can work in your case, but jasper report have display expression.

hello, 

you use a default variable called $V{Page_Number} with the evaluation Time set as "Now" for the current page, or the "x" in your example
and use the same variable (yes the $V{Page_Number} with the evealuation Time set as "Report" for the sum of all page in the report ( the "Y")

Hope this helps :D

Best Regard,

Hi,

Yep, that's what i'm doing ; the issue is about using it for "print when expression".
I want to display fields only on some particular pages, according to their number.

You can try add count records in the query, compare it with $V{PAGE_COUNT} and use that as your Print When Expression. Basically it compares the total number of records with the number of records in current page so you will know if you have more than one page. It's not elegant and it's not correct when you have summary band in separate page by itself but that's a workaround I could think of.
