I am successfully converting many URLs to PDFs, then merging them into 1 PDF. However, I am struggling to have the footer page numbers be accurate for the entire PDF. How can the footer know how many pages there are in the entire PDF because it is made up of so many PDFs merged together? Although there are 15 pages in the entire PDF, I am seeing page 1 of 2, then page 2 of 2, then page 1 of 3, etc.; it keeps restarting.



PdfDocument doc = new PdfDocument();
HtmlToPdfOptions opts = new HtmlToPdfOptions();
opts.HeaderHtmlFormat = String.Format(@"<center><br/><b>Date:</b>{0}<br/><br/><b>Event:</b>{1}<br/><b>Username:</b>{2}</center>",
System.DateTime.Now.ToString("dd-MMM-yyyy h:mm:sstt"), "R2342335644", username);
opts.FooterHtmlFormat = @"
<hr />
<div style=""text-align:center"">
Page {page_number}/{total_pages}
</div>
";
opts.RepeatTableHeaderAndFooter = true;
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://CRF/Default.aspx?SelectedID=2097873", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://CRF/Default.aspx?SelectedID=2098829", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http:// CRF/Default.aspx?SelectedID=2098908", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://EventAuditTrail.aspx?EventID=2097849", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://ManageOneEvent.aspx?EventID=2097849", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://CRF/AdjFormsForEvent.aspx?EventID=2097849", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://CRF/ClinicalCRFs.aspx?EventID=2097849", doc, opts));
HtmlToPdf.Options.Follow(HtmlToPdf.ConvertUrl(@"http://SourceDocs/SourceDocs.aspx?EventID=2048446", doc, opts));
doc.Save(@"c:\visual studio 2010\Projects\ConsoleApplication2\ConsoleApplication2\bin\Debug\Event.pdf");

eo_support, I tried the code you suggested and the page numbering worked. But I was disappointed that the outputarea seemed to vary widely from page to page. It did not look good, although I used the same rectangle for each page. Any thoughts you can give me concerning the layout and positioning of this outputarea will be appreciated.

for (int i = 1; i < doc.Pages.Count; i++)
{
PdfPage page = doc.Pages[i];

//You need to set the OutputArea properly so that the output
//goes to the bottom of the page (or anywhere else you want it
//to go)
HtmlToPdf.Options.OutputArea = new RectangleF(0f, 1f, 1f, 2f);

//The first argument is your footer HTML. At this point you already
//have information about everything, such as total page numbers
//The second argument is the PdfPage object

HtmlToPdf.ConvertHtml(string.Format(
@"<div style=""text-align:center"">
Page {0}/{1}
</div>", i + 1, doc.Pages.Count), page);
}
