Help on one jasper report please

[mohammed.sardar]

Hi All,

I have designed a jasper report where I have column header followed by details and one more sunreport in a Group Footer. So how the report works in it will print the first report data and then followed by sub report data. What I want to do is I want to hide the column headers of Report 1 when there is no data for the header report.

To cut the story short the column header should be hidden if there is no data. I searched through the net but could not find a clue to make it worl. Could you please some one guide me on this

Many Thanks

Mohammed

So, to do this; you need to use the PrintWhen Expression of the Header band, that expresion if evaluates to TRUE, will not print the header band. Here is a nice thread about using this type of expressions http://stackoverflow.com/questions/294989/how-to-use-printwhenexpression-in-jasperreports
