Hi,
EO pdf is used to generate pdf reports from html page, we need solution to implement Back to top page functionality from end of each page.
Indexing has been implemented using href and div id. This is working fine as the table of contents and data is in same html page.
At the end of each page, we are trying to navigate back to Top page/Table of contents. But it’s not possible as the footer and data template are in different html pages.

Footer Template code:
FooterHtmlFormat = "<hr><a href=#bookmark-toc>Back to Top</a><div style = 'text-align:right;font-size:12px;' > " + localizedEncodedPage + " {page_number}</div>";



Data template code:

ConvertHtml(@"<div id='bookmark-toc' class='report-title' style='width:100%;text-align:center;font-size:18px;font-family:Arial;text-align:center'>"
+ this._reportName +
"<br/><span style='font-family:Arial;font-size:11px;'>" +
fromTimeHeader + toTimeHeader + "</span></div><script>if (typeof eoapi != 'undefined') { if (typeof (eoapi) == 'object') { eoapi.convert(); }}</script>", e.Page);

Hi,

You will not be able to use FooterHtmlFormat to do this because you can't navigate from footer to the main contents. The easiest way for you to do this is to convert the main contents first, then convert the "navigator" over the original result. The "navigator" HTML will be something like this:

Code: HTML/ASPX 
<!--for the first page-->
<div style="page-break-after:always;">
    <a name="top_1"></a>
    <div style="height:800px"></div>
    <a href="#top_1">go to top</a>
</div>
<!--for the second page-->
<div style="page-break-after:always;">
    <a name="top_2"></a>
    <div style="height:800px"></div>
    <a href="#top_2">go to top</a>
</div>
......and so on......


Your actual code will be something like this:

Code: C# 
//Create a new PdfDocument object
PdfDocument doc = new PdfDocument();

//Convert the main content
HtmlToPdf.ConvertHtml(main_content_html, doc);

//Generate your navigator HTML based on how many pages your main contents has
string navigatorHtml = GenerateNavigatorHtml(doc.Pages.Count);

//Output the navigator HTML into the same PdfDocument
HtmlToPdf.ConvertHtml(navigatorHtml, doc);


You may need to set HtmlToPdf.Options.OutputArea before you convert your navigatorHtml so that the HTML will fit into header/footer area. You will also need to adjust the div's height (in the above sample 800px is used). The purpose of that DIV is to push the second link down.

Hope this helps. Please feel free to let us know if you still have any question.

Thanks!

Hi

Whether GenerateNavigatorHtml method is a EO pdf method or custom method.
Can you elaborately explain the functionality of GenerateNavigatorHtml method.

Awaiting for your Reply,

This is a method you need to implement in order to generate the HTML similar to the one shown in our previous reply.
