Hi

I am Exporting MSWORD from HTML Stream using Aspose.Word .

I use builder.InsertHTML() to which I pass HTML stream . To add page break I use this

<p style='ms-special-character:line-break;page-break-before:always'>&nbsp;</p>

which works fine it adds page break and all that …

Now I wan to add Header and Footer and in Footer I want to show page number.

at some point I want to reset page no. to 1 again

How to achieve this ?

Regards ,
Jeevan Joshi.

Hi Jeevan,

Thanks for your inquiry. Please note that you can not insert header/footer by using DocumentBuilder.InsertHtml method.

The HeaderFooter class represents a container for the header or footer text of a section. HeaderFooter is a section-level node and can only be a child of Section. So, header and footer repeat on each page of a section. There can only be one HeaderFooter or each HeaderFooterType in a Section.

You can insert header/footer after calling DocumentBuilder.InsertHtml method and insert page number field in footer of a section as shown in following code snippet.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.InsertHtml("<P align='right'>Paragraph right</P>" +
    "<b>Implicit paragraph left</b>" +
    "<div align='center'>Div center</div>" +
    "<h1 align='left'>Heading 1 left.</h1>");

InsertHeaderFooter(builder.CurrentSection, HeaderFooterType.FooterPrimary);
InsertHeaderFooter(builder.CurrentSection, HeaderFooterType.HeaderFirst);

builder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
//Set start number
builder.PageSetup.PageStartingNumber = 1;
//Page numbers will be restarted for each section
builder.PageSetup.RestartPageNumbering = true;
//Insert PAGE field into the header
builder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
builder.Write("Page");
builder.InsertField("PAGE", string.Empty);
builder.MoveToDocumentEnd();
//Insert page break
builder.InsertBreak(BreakType.PageBreak);
//Insert section break
builder.InsertBreak(BreakType.SectionBreakNewPage);

doc.Save(MyDir + "Out.docx");

private static void InsertHeaderFooter(Section sect, HeaderFooterType headerType)
{
    HeaderFooter header = sect.HeadersFooters[headerType];

    if (header == null)
    {
        // There is no header of the specified type in the current section, create it.
        header = new HeaderFooter(sect.Document, headerType);
        sect.HeadersFooters.Add(header);
    }
}

Section can have one Body and maximum one HeaderFooter of each HeaderFooterType. Body and HeaderFooter nodes can be in any order inside Section.
