Nested Paging/ Section wise Paging / Sub Pager

Aspose.PDF Product Family
1

Requirement:
To have a overall paging on the document i.e. Page 1 of 20
To have section wise paging as well i.e. Page 1 of 5.

Problem:
We are unable to display section wise page.

Approach:

Overall paging
For overall paging, we have used

TextFragment hfHeaderTxt2 = new TextFragment(“Page $p of $P”);

The above code is being called in “page.OnBeforePageGenerate” event. (see line#258 in pdfHelper.cs)

Section wise Paging
Our document contains multiple section. Each section may render on multiple pages. For example: we have 2 sections i.e. “section ABC” and “section XYZ”.
Content of “section ABC” renders in 3 pages. so each page header should show
“Page 1 of 3”, “Page 2 of 3” and so on.
Paging should be reset when a new section starts.

We are managed to print the page number and able to reset when new section starts (see implementation in AddHeader method at line#229). We are unable to get the total count of pages a section will take, hence not able to show total count of page.

Please see the attached [PdfGenerationApplication.zip]
Addmethod at line#158 is the method responsible for creating pdf docuement. This method calls OnPageGenerate event responsible for displaying header and paging.

Please always share SSCCE code and never include license in attachments. You can also delete the files in packages folder which can later be restored from NuGet at our end.

Moreover, how do you distinguish between different sections because total number of pages per section would need to set accordingly. Would you please simplify your use case as per SSCCE because it includes a lot of information that can probably be minimized further in a separate solution or code snippet.

Thanks for your reply. Please use this [link](https://drive.google.com/file/d/1pORoanOuapVenD0_GH466wOaLJcCdhwI/view?usp=sharing) to download updated sample project

I have made changes you mentioned. Please only look for

AddHeader(page, sectionId);
in pdfHelper.cs > GeneratePdf() > OnPageGenerate() > AddHeader()

We identify each section by its id.
In GeneratePdf method , we loop through each section (line#169) and add “AddHeader” method on “OnBeforePageGenerate” event (line#176). AddHeader method is responsible to populate the header details on addition of a new page of a section.

AddSectionContent(page, procedureEntity, section.Id, generatedFiles);
(line#178) is responsible to populate the content of a section.

I need help in AddHeader method to know how to find total page a section will take while rendering, so that i can display it on a page header i.e. Section Page 1of 5.

Hope the requirement is clear now.

Thank you for elaborating further.

We are afraid number of pages may not be counted while adding the content so we have logged a ticket with ID PDFNET-47098 for further investigations. We will let you know as soon as any update will be available in this regard.

Thanks for the reply.

Is there any possibility, that after rendering the content and creating all the pages. We access each page again and update total page count in each page, as now we have idea of total pages generated

@sanobar_nishat

After generation of PDF, distinguishing between different sections can be tricky. We will be able to share some work around if possible, once the ticket will be investigated.
