Hi,

 

You simply place the subreport on the page header

an maybe use its <printWhenExpression>

to display it only once, on the first page or whatever.

If it is about displaying it only on the first page,

then you might as wel consider placing it on the

title section of the report.

 

For details about how to use subreports, check

the supplied "subreport" sample.

 

I hope this helps.

ur right I need only once.....I tried placing subreport on title but it never finished compiling, then I put it on title and changed the subreport band to details then data is visible but report design goes for a toss.........

 

and what should the "print when expresion " have?

 

Its urgent..............

 

 

thanks

Hi,

 

It would be interesting to see the report compilation

error before going to complicate things with the

printWhenExpression.

However, such an expression should check the

PAGE_NUMBER variable like this:

 

<printWhenExpression>

new Boolean($V{PAGE_NUMBER}.intValue() == 1)

</printWhenExpression>

 

I hope this helps.

Hi,

 

You are no supplying to your report any

data source.

You are only supplying a parameter

called "InvoiceNumber" and I'm not sure what

the subreport is supposed to do with it.

 

You have to use either <connectionExpression>

or <dataSourceExpresison> tags so that the

subreport could iterate on something.

Since I see that the subreport does not have

an SQL query, I guess it is the

<dataSourceExpression> that you nees to pass

in to the subreport a custom JRDataSource object.

 

Anyway, if you want a report/subreport to generate

something even if there are no records in the data

source (null data source in you case),

use whenNoDataType="AllSectionsNoDetail".

If you do that for your subreport, you can see it

is there, but it has no records.

 

I hope this helps.
