Page numbers in table headers [message #667670] Sun, 01 May 2011 02:51 Go to next message

I am trying to selectively print table header rows depending on the page number. How can I do this in java script. My problems are
1.Can I use the visibility property of the table row?
2.What is the java script field name for the page number variable?

Due to other problems I have, I am not able to use the Master page for the page header as it contains data from the table. When I set the header grid to the same dataset as the table no data comes out in the table, hence my problem.

I wish to print one table header row if the page number=1 and another if the page number >1

Why not use a page variable and script for this? As an example assume I
have order details in a report. One of the columns is qty ordered. I
can name that element and then reference its value in a page script.
Like onPageEnd:
var qtys = this.getInstancesByElementName("qtyelement");
var tmp=0;
if( qtys != null ){
for( var i=0; i< qtys.length; i++ ){
//Instance of DataItemInstance
var qty = qtys[i];
tmp+=parseInt(qty.getValue());
}

}
reportContext.setPageVariable("pageqty",tmp);

Then I can use the pageqty page variable in my header. See attached
example.

Thanks Jason. I noticed that you set the aggregation up as a script on create. I recreated your report just with this aggregation. The total was correct for the HTML 1 page report, but as a PDF the total was differant on the last page. Is this an error in BIRT when doing aggregations? Do all aggregations need to be set up in scripts to guarantee that they will always be correct?

I am not seeing the error you are seeing. The aggregation oncreate
script is only there to take the value that is created and store it in a
global variable that I use in the page script.

Sorry Jason had forgotten that BIRT designer only lists the first 500 records but when you run a PDF version you get the whole file.
Chris.

Thanks for your help
