dynamic addition of columns???

[antzjos]

Hi All,

 

Is it possible to add columns dynamically to the report. If yes, pls let me know how to do it.

 

thnx.

Basically no. A report just is a snapshot after all - you have to define all your columns before JasperReports can fill the output. So once the report generation is underway there's no way to change the source query.

 

BUT!!! You can do it in reverse. Make sure your query returns all the columns that you will ever need to display and then selectively remove them from you report.

 

Please note that the layout control is particularly difficult with this option. If you want to avoid leaving gaps where columns are omitted you will need to use some very intelligent Text Field and Print When expressions.
