Manipulating JasperDesign

[tah]

Hello,

I need to dynamically change my report design by doing the following:

1- removing a text field from the detail band

2- replacing it with one or more other text fields

3- adding the necessary fields to match the text fields

 

Step 3 can easily be done with myJasperDesign.addField(myJRField).

However the closest I can get to doing the first two points is to find the JRDesignTextField in my detail band (myJasperDesign.getDetail().getElements()) but I can't remove it nor add anything else to the detail band.

 

Any help would be appreciated.

Can't you use the: printwhen expression from your texftield?

 

<printWhenExpression>

<![CDATA[new Boolean($V{VERSCHIL}.doubleValue() < 0)]>

</printWhenExpression>

 

So if my variable VERSCHIL<0 my textfield will be printed. If not, it won't be printed :)

getDetail() will return a JRDesignBand instance when called on a JasperDesign object, so cast it to JRDesignBand and you will find methods for adding and removing report elements.

 

HTH,

Thank you very much Lucian that is exactly what I needed. I'll get to it right away.

 

And thank you too Giroe but that is not what I was looking for. I have to change the whole detail band and add some new fields that I did not know about at design time :)
