Hi I am working on jasper reports past 15 days. I want some help , when i am using detail band to display the rows it working fine ,but when there is a null value in the fields or i want to ignore the line it will work by writing the logic in "print when expression" ,then it leaves blank space between rows,but i want that space also saved and no blank space is seen. So there is any property to handle such a problem. please anyone know this please replay it to me. my email id is vasamsetti_prasad@persistent.co.in Thanks and regards, Prasad.
