LocalHyperlink and Target Page Number

Where are evaluating Aspose.PDF. We have found and or confirmed several issues with Footnotes and Endnote that are listed in your support page which hopefully will be addressed soon.
We have another scenario where we are creating a PDF using Aspose.PDF DOM. This is accomplished by looping through some custom hierarchical objects and create various Tables etc. During this process references are encounter that are somewhat like End Notes. When a reference is encountered, a Text Fragment is created, with a Text Segment and that Segment gets a LocalHyperLink created. The actual reference Text will be listed on the last page. How can I set the LocalHyperLink’s TargetPageNumber when I do not know what the last page number will be? Any help greatly appreciated.


Thanks for contacting support.

Before setting the TargetPageNumber, please call ProcessParagraphs() method of Document object. This way you will get correct page count of PDF before it is saved. In case you still face any issue, please share your sample code snippet along with sample PDF document, so that we can test the scenario in our environment and address it accordingly.

Thanks. Can you provide an example? I 'll try to get a sample together as our current application is rather large.
Thanks again.


Thanks for writing back.

Please check following code snippet which demonstrates a basic use of ProcessParagraphs() method, in order to get last page number and add a hyperlink for it. For your reference, an output is also attached.

Document doc = new Document();
var page = doc.Pages.Add();
Table table = new Table();

Row Header = new Row();
TextFragment tf = new TextFragment("New Line");
Row r = new Row();
int i = 0;
while (i < 180)
table.RepeatingRowsCount = 1;

int countbefore = doc.Pages.Count;
int countafter = doc.Pages.Count;

Console.WriteLine($@"Before ProcessParagraph => {countbefore} and After ProcessParagraph => {countafter}");

TextFragment t = new TextFragment("Goto Last Page");
t.TextState.ForegroundColor = Color.Blue;
t.TextState.Underline = true;
LocalHyperlink link = new LocalHyperlink();
link.TargetPageNumber = doc.Pages.Count;
t.Hyperlink = link;
HeaderFooter footer = new HeaderFooter();
doc.Pages[1].Footer = footer;

doc.Save(dataDir + "PageBreakTable.pdf");

Thanks for sharing sample project and PDF document.

We are looking into the scenario and will get back to you shortly.


Thanks for your patience.

Please check attached sample console application, which will generate PDF file as per your requirements, where hyperlinks will point to respective note at the last page. For your reference, a sample output PDF is also attached, which was generated by attached sample project.

Thanks for the example. Very helpful. Although found that if a table row is a header row and has a link to a LocalHyperLink and the table breaks across pages the Hyperlink in the Header of the the Table on the second page does not work. See Table named ‘DNGXWRC’
Attached PDF and sample code.
