i also encountered same requirement, actually i want to set the value of height and width property of reportElement from field value

example code is given

but getting this error:

net.sf.jasperreports.engine.JRException: org.xml.sax.SAXParseException: cvc-datatype-valid.1.2.1: '$F{PositionX}' is not a valid value for 'NMTOKEN'

Hiii guys..

 

I have worked on some crossTab reports, but dont know whether we can achieve the changing of reportheight dynamically..but we can disable fields in report. Just pass condition in editExpression.

 

Eg

($V{field}.equals("a") ? $P{parameter1} : $P{parameter2}...

 

You should pass field value while populating values to report(mean to say set Field("a"), Field("b")...).

 

 

Hope this is the doubt you all have and iam clear in my explaination

Thanks for your quick reply, now i can hope that their is some to help me.

 

But actually my requirement is a little different, actually i want to design the jasper report base on the values from the database, means i store elements x,y,width,height,style etc. to database, then i retrieve that values from database using queryString of jasper report, now i want to set these x,y,width,height values to the reportElement x,y,height,width

 

such as: <reportElement x="<here will be the xfield value from database>"/>

i use this <reportElement x="<![CDATA[$F{xfield}]]>"/>

but not working...

what can be the solution
