Indicate a subtotal of pages in a PDF report on Genexus

I need to create some documents in Genexus indicating the number of pages for each document separately To clarify better, I need to create a 6-page report in which the first 2 belong to one document and the remaining 4 to another At the moment, thanks to the &Page variable and the {{Pages}} command (for which I can't find any documentation, I only know that it was suggested to me many years ago) I can indicate the ratio between the current page number and that of total pages

1 / 6
2 / 6
...
6 / 6

I would need though if there is a way to have a subtotal so that the two documents have the totals shown separately. I would like to get this type of numbering

1 / 2
2 / 2

1 / 4
2 / 4
3 / 4
4 / 4

I can manually reset the Page variable, but I don't know how to do it for the total number of pages, I can't even calculate it in advance. Is there a way to solve this, perhaps with other commands similar to {{Pages}} ? Where can I find documentation on these?

If the row height is fixed, you can calculate the number of pages in advance because you will know how many rows will be on each page.

Although not efficient, I found two solutions: one is to generate the files separately and merge them via a user control, another is to generate them separately as "temporary files", receive the length of the document as an output parameter (the &Page variable) and use this parameter as a total for the corresponding section. Then I delete the temporary file.

Pretty crude, but it worked

You could try with auxiliar variables to keep the page count:

  • &TotalOfPages=Numeric(4)
  • &CurrentPage=Numeric(4)

Before the print command add this code on Source:

If &Page <= 1
    &TotalOfPages = 2
    &CurrentPage = &Page + 1
Else
    &TotalOfPages = 4
    &CurrentPage = &Page - 1
EndIf

Then in the layout where you have

&Page of {{Pages}}

replace with:

&CurrentPage of &TotalOfPages
