Hello ,

I try to add custom header and footer in a radDocument, but when I do , i can only write a single page . When going to the second page the editor disappears here's the function i'd like to use

public void InsertPageLayout()

{

Section section = this.RichTextBox.Document.Sections.First;

section.HasDifferentFirstPageHeaderFooter = false;

this.RichTextBox.Document.HasDifferentEvenAndOddHeadersFooters = false;

RadDocument footerBody = new RadDocument();

footerBody.LineSpacing = 1.15;

footerBody.ParagraphDefaultSpacingBefore = 5;

footerBody.ParagraphDefaultSpacingAfter = 5;

footerBody.SectionDefaultPageMargin = new Padding(95);

Section sectionF = new Section();

Paragraph p = new Paragraph();

Span s = new Span();

s.Text = "Footer";

p.Inlines.Add(s);

sectionF.Blocks.Add(p);

RadDocument headerBody = new RadDocument();

headerBody.LineSpacing = 1.15;

headerBody.ParagraphDefaultSpacingBefore = 5;

headerBody.ParagraphDefaultSpacingAfter = 5;

headerBody.SectionDefaultPageMargin = new Padding(95);

Section sectionH = new Section();

Paragraph ph = new Paragraph();

//ph.LeftIndent = 0;

ImageInline im = new ImageInline(this.GetResourceUri("images/Lighthouse.jpg"));

/*if (im.UriSource == null

{

BitmapImage imSource = new BitmapImage();

}*/

double pixelHeight = im.ImageSource.PixelHeight;

double pixelWidth = im.ImageSource.PixelWidth;

double proportion = pixelHeight / pixelWidth;

bool portrait = true;

double largeur;

if (portrait)

{

largeur = 21 / 0.0264;

}

else

{

largeur = 29.7 / 0.0264;

}

double margeHaut = 1;

double margeBas = 1;

double margeGauche = 1 / 0.0264;

double margeDroite = 12 / 0.0264;

double largeurImg = largeur - (margeGauche + margeDroite);

double hauteurImg = largeurImg * proportion;

// Convertir cm en unité px

im.Width = largeurImg;

im.Height = hauteurImg;

Span sh = new Span();

sh.Text = "Header";

//ph.Inlines.Add(im);

ph.Inlines.Add(sh);

sectionH.Blocks.Add(ph);

//sectionH.ActualPageMargin = new Padding(0, 0, 0, 0);

headerBody.Sections.Add(sectionH);

footerBody.Sections.Add(sectionF);

Header header = new Header() { Body = headerBody, IsLinkedToPrevious = false };

Footer footer = new Footer() { Body = footerBody, IsLinkedToPrevious = false };

//document is an instance of RadDocument, representing the content of the footer,

//document is an instance of RadDocument, representing the content of a Header,

//typically contains a few paragraphs

//section.Headers.First = header;

//section.Footers.First = footer;

//header.Body.InsertReadOnlyRange(startPosition:new DocumentPosition(headerBody), endPosition:new DocumentPosition(headerBody));

//footer.Body.InsertReadOnlyRange(startPosition: new DocumentPosition(footerBody), endPosition: new DocumentPosition(footerBody));

RadDocument footerBody2 = new RadDocument();

Section sectionF2 = new Section();

Paragraph pf2 = new Paragraph();

Span sf2 = new Span();

sf2.Text = "Footer 2";

pf2.Inlines.Add(sf2);

sectionF2.Blocks.Add(pf2);

RadDocument headerBody2 = new RadDocument();

Section sectionH2 = new Section();

Paragraph ph2 = new Paragraph();

//ph2.Inlines.Add(im);

Span sh2 = new Span();

sh2.Text = "Header 2";

ph2.Inlines.Add(sh2);

sectionH2.Blocks.Add(ph2);

headerBody2.Sections.Add(sectionH2);

Header header2 = new Header() { Body = headerBody2, IsLinkedToPrevious = true };

Footer footer2 = new Footer() { Body = footerBody2, IsLinkedToPrevious = true };

//Section section2 = new Section();

//section2.Blocks.Add(new Paragraph());

//section.Headers.Even = header2;

//section.Footers.Even = footer2;

//section.Headers.Default = header;

//section.Footers.Default = footer;

this.RichTextBox.UpdateFooter(section, HeaderFooterType.Default, footer);

this.RichTextBox.UpdateHeader(section, HeaderFooterType.Default, header);

this.InsertPageLayoutResponseComplete(this, null);

}

public event DownloadStringCompletedEventHandler InsertPageLayoutResponseComplete;

private void OnInsertPageLayoutResponseComplete(object sender, DownloadStringCompletedEventArgs e)

{

if (InsertPageLayoutResponseComplete != null)

{

InsertPageLayoutResponseComplete(this, e);

}

The exeption is
