printWhenExpression - solved

[wegnerk]

Hi again,

 

i want to print a columnheader when it is the first page for all kind of docs and only for pdfs on the other pages.

So, i have a report with a parameter "fileformat" (string) and export it to pdf, xls and csv. But the pageheader should only be printed for pdf on all sides and for the other two formats only on the first page.

 

how should the "printWhenExpression" look like exactly?

 

thanks in advance

ok, first think, then ask... ;)

 

i found a suitable expression myself.

Can you share the logic please?

[wegnerk]

of course, sorry....

 

i have a parameter "fileformat" (string) and i just had to give the pageheader an own printWhenExpression:

 

Code:

<pageHeader>
<band height="83"  isSplitAllowed="true" >
<printWhenExpression>
 <![CDATA[boolean(!$P{Fileformat}.equals("csv"«») &&  
 $V{PAGE_NUMBER}.intValue()==1)]]>
</printWhenExpression>
...
</band>
</pageHeader>

like this... so the pageheader will be printed when the fileformat is not "csv" and the pagenumber is 1.

 

not difficult, but i forgot that i can have more than one expression (with && or ||)...

Hi,

I have a problem in dynamic display of pageHeader. In my case I do not know if the main report will be starting from page 1 or 2 or 3. As there is another subreport in the <title> band.

 

 

The subreport in the <title> band is displayed based on a condition(boolean).

 

Do you have any solution for this?

Hi,

 

I think you could try return the PAGE_NUMBER variable from the subreport.

Our sample in /demo/samples/subreports shows how a value could be returned from a subreport to the master report.

 

I hope this helps.
