Manage Visibilty of component / Band in iReport Jasper Report

A band becomes invisible in the report if its height is set to zero.
We can also make a band invisible using the Print When Expression option. If we write new Boolean(false) in “Print When Expression” of a band, then that will make the band invisible, even though its height is set to greater than zero. If we write new Boolean(true), then the band will be visible. It is true by default.

you can also setup band to be invisible with use of Parameter of type boolean

Create a parameter and write the “$P{ParameterName}” in “Print When Expression” of band.

Subreport not displayed in main Jasper Report ireport

Hi
I am sure somebody would face this problem..
Using ireport 3.7.2

Subreport in Ireport is not displayed until I do the following.

Remember to set properties of subreport (Also if ur using a static text to display in subreport)

Connection Type >>>> Use a datasource expression
Data Source Expression >>>> new net.sf.jasperreports.engine.JREmptyDataSource()

Make Sure you select “When No Data” Property to All Section No Details. most of the time Problem would be that data being set properly to subreport.
