adding a coloumn dynamically

[neha_dhingra]

Hi Friends,

 

How can we add or remove coloumns dynamically in Jasper Reports?

 

thoughts?

 

Thanks,

Neha

It's a little like adding JTextField on a JFrame in swing.

 

The simpliest is to look at the example in "Demo" directory of JasperReport.

See "demosamplesnoxmldesignNoXmlDesignApp.java"

 

Examine the method :

"private static JasperDesign getJasperDesign"

 

especialy see some code like :

 

Code:

field = new JRDesignField();
field.setName("FirstName"«»);
field.setValueClass(java.lang.String.class);
jasperDesign.addField(field);

 

When you see the whole code, you understand that you have to get the section as desingsection, then construct a field as designfield and after add your field to the desing section.

 

It takes time but it worth it

Thank You Aristide :)

hi neha

 

 

I dont know about the code given above, but for adding the field dynamically you need to use Velocity framework.
