  In a Section Report, I see the documentation says Page {PageNumber} of {PageCount} has a toll on performance. How much of an impact is it? Where is the best place to use PageCount, in the page header, footer, or not at all ?
  
  Thanks

  Hello,

  When you place the PageCount in Report header/PageHeader, it will impact the performance. I will suggest you to use “PageCount” in the PageFooter so that performance will not affect.

  How much of an impact is it?
  
  Sorry to mention that currently, we don’t have any statistical data to judge the performance difference.

  Thanks.

  PageFooter has a much lower impact? Interesting, I’m tempted to ask what is the difference between the top of the page and the bottom but I will take your work for it. OK, for big reports that’s where it will go. Thanks

  Hello,

  Height of each section is count in Format event of section. The sequence to of firing of Format event of PageHeader, PageFooter, Detail section as below:
  
  PageHeader_Format> Detail_Format> PageFooter_Format

  If you add the page count/total in Page Header then ActiveReports must determine the total or page count of the sections before it can render the header section which slows the process.

  If you add the page count/total in Pag Footer then the height of other section is already calculated in other section which helps in increasing performance as compared to when you add the page count in the header section.

  Hope it clarifies.

  Thanks.
