Setting Report Variables

sschafer2

Hi,

The problem I'm trying to solve (in version 2.5.1) is to display page n of m on the page header where n and m are the page number and total page numbers of a group, not the whole report. I've been able to compute the page number pretty easily in javascript and then I use reportContext.setPageVariable() to set it to a predefined page variable which I have put in the page header.

The problem I'm facing now is how to get the m value (the total number of pages for the group). I think that using a report variable as defined in the data explorer might do the trick but I can't figure out how to set it. While reportContext has a setPageVariable() it does not have a setReportVariable(), and I don't think setGlobalVariable() or setPersistentGlobalVariable() are what I want.

So, two questions really. Will a report variable give me the look-ahead capability I need to set the page counts, and if so, how do I set it?

Thanks
Steve

Hi Steve,

I don't know that there's a good way to grab the pages per group. The way I've done this before was to calculate the group pages based on the page break interval or an interval group within your group. I'll have to look around to see if there a way to use a report variable to access this value.
