Problem with stretch

[diegocardoso]

 I'm developing one report wich has two sub-reports placed side-by-side as columns. The problem that I've got is that when one subreport is taller than the other (wich is expected to occurs always), the smaller one doesn't stretch. Both stretch types are set as "Relative to Band Height" and they don't work when I set as "Relative to Tallest Object" either.

Each sub-report has the same structure: a column header, a group header, and a column footer. I don't know if I have to set an object in each sub-report to stretch when the other one gets taller.

Any help is welcome!

 

Thanks.

Stretch type of "Relative to Tallest Object" will only work with subreports if they have a background color set and the "Opaque" setting is TRUE.  Even then the stretch won't extend beyond one page, so it's not a great solution.

Since each subreport is evaluated independently it is not possible to exchange information between them about how many rows are being returned.

However, you can put a subreport into the page header that returns the count of rows for each query.  Those values could then be used to make decisions about how to adjust the output of the subreports.  Just how you would do that is up to you.

But the easiest way to overcome you problem is to use ONE subreport with one query.  Format the subreport to output the information as if there were two.  Use printWhenExpression if necessary to remove objects when your query returns NULLs, empty strings, zeroes etc.
