Hello Thomas,
Generally, a span that contains "\n" in it is considered invalid, so you shouldn't be using this method when creating your document. The proper way to add a line break would be the second approach you mentioned - inserting FormattingSymbolLayoutBox.LINE_BREAK. The ¬ character, on the other hand, is the symbol used for adding line breaks in the document.
So, a correctly structured document would look something like this:

RadDocument document=new RadDocument();

Section section = new Section();

Paragraph paragraph1 = new Paragraph();

Span span1 = new Span("Some text in the first span. ");

paragraph1.Inlines.Add(span1);

paragraph1.Inlines.Add(new Span(FormattingSymbolLayoutBox.LINE_BREAK));

Span span2 = new Span("Some more text after the line break in the same paragraph.");

paragraph1.Inlines.Add(span2);

Paragraph paragraph2 = new Paragraph();

Span span3=new Span("Last paragraph");

paragraph2.Inlines.Add(span3);

section.Blocks.Add(paragraph1);

section.Blocks.Add(paragraph2);

document.Sections.Add(section);

and will indeed contain the ¬ character when exported to XAML, for example.

I also tried exporting to PDF the document above and it all looks good on my end. Can you please verify that and contact us again if you are observing different behavior?

Let me know how it goes.

Hello,

Could you elaborate a bit more on the scenario you are working on? The screenshot of your code is not enough to fully replicate the case. Please have in mind that Sections are positioned above Paragraphs in document's Element Hierarchy. This is why the same approach working for inserting Page Breaks might not work for inserting Section Breaks.A sample project illustrating both approaches you are working on will help in isolating the issue.

In the meantime the code below shows a possible approach to insert a Section Break using RadRichTextBox' Search functionality.

this.radRichTextBox.Document.Selection.Clear(); // this clears the selection before processing

DocumentTextSearch search = new DocumentTextSearch(this.radRichTextBox.Document);

foreach (var textRange in search.FindAll("\\[Section Break\\]"))

{

this.radRichTextBox.Document.Selection.AddSelectionStart(textRange.StartPosition);

this.radRichTextBox.Document.Selection.AddSelectionEnd(textRange.EndPosition);

}

this.radRichTextBox.InsertSectionBreak(SectionBreakType.Continuous);

It finds the string passed as an argument to FindAll() method and inserts Section Break over its place.

Hope this helps.
