Question

I have a main report and a subreport and i want to hide a textfield based on the value returned by the subreport.

How to achieve this in jasper ireport?

Answer 1

You need to pass value returned from subreport to main report. If you use Jaspersoft Studio find Subreport Return Values in subreport properties :

So in this table you can set from which value in subreport to which in main report you will pass you values. Then you can access subreport value from main report variable.
