  Hello,

  Assuming that you are using C1FlexReport, please inform about the use-case based on which you intend to use parameters for displaying page numbers.
  
  The below mentioned code can be used to set calculated page numbers in a TextField, at run-time:
  
  ```
  
  TextField tf = new TextField();
  
  tf = (TextField)c1FlexReport1.Fields[“ftrRight”];
  
  tf.Text.Expression= “"Page " & [Page] & " / " & [Pages]”;

  
  Further, values of parameters used in a report can be fetched as follows:
          ```
      c1FlexReport1.Parameters[0].Value = 10;
              Console.WriteLine(c1FlexReport1.Parameters[0].Value);
  

  Once a report has finished rendering, you can fetch the pages, as follows:
  
  ```
  
  private void c1FlexReport1_EndReport(object sender, EventArgs e)
  
  {
  
  Console.WriteLine(c1FlexReport1.PageCount);
  
  }

  Refer the attached application for the implementation.
  In case it does not help, please elaborate on the requirement so that I can assist you further.  
   
  Regards,
  Esha

  Hello,

  This expression is not correct as the value in [Pages] is generated after complete rendering of the report. Thus, this addition to a specific value will not work here for the page total.
  
  An alternative is to re-render the report so that we have a PageTotal in hand first. This can then be used to add to a default value and generate the expected results.
  
  The modified application showing the same is attached for your reference.

  Thanks.

  HI esha.dhir, thansk for answer. but i have a wrong when run my example with your suggestions.
  
  private pageTotal = 0;
  
  c1FlexReport1_EndReport()
  
  pageTotal = c1FlexReport1.PageCount;

  c1FlexReport1_StartSection()
  
  if (e.Section == SectionTypeEnum.PageFooter)
  
  {
  
  TextField tf = new TextField();
  
  tf = (TextField)c1FlexReport1.Fields[“ftrRight”];
  
  int pageDefaut = 5; // parameter from report 1
  
  int total = pageTotal + pageDefaut;
  
  tf.Text = "Page " + (e.Page +pageDefaut) + “/” + total;
  
  }
  
  => Total of report 2 is not true. because Total variable only exit when report EndReport() function runed,
  
  => in StartSection() Total is only pages of report 1 anytime
  
  EX: report 1 return 5 pages
  
  report 2 is show: page 6/5 …->… page. 10/5
  
  where is wrong ?

  Hi,

  Have you used report 2 as the same report instance?
  
  Note that I have called Render method twice in the button’s event handler:

   private void paraButton_Click(object sender, EventArgs e)
  {
  ....
  [b]  c1FlexReport1.Render();
  [/b]            //Render again. This time, the PageCount from the previous rendering is used to get the total page count and then add the default variable value to it.
  [b]           c1FlexReport1.Render();[/b]
   c1FlexViewer1.DocumentSource = c1FlexReport1;   
  }
  

  Did you do it in the same manner in your application?

  Thanks.
