RadDocument Insert LineBreak in span

[Thomas]

I am inserting some text that conains linebreaks, "\n", into a new Span in a RadDocument based on a docx template and then I save the document as a PDF using the PDF provider.

The problem is that there is everything is printed on the same line and the LineBreake itself i replaced by two Squares (i asume that is since the LineBreak character is not recognized).

I have tried replacing the LineBreak with "FormattingSymbolLayoutBox.LINE_BREAK", but the text is still on one line and I get a ¬ character instead of the two Squares.

Is it impossible to insert a LineBreak inside a Span, or is it possible to fix this?

Please note that I am only using the RadDocument class and that I am not and do not want to use the actual RichTextBox Control!

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.

Using FormattingSymbolLayoutBox.LINE_BREAK within a Span worked for us until we recently upgraded to version 2015.1.401.45. Now our document literally displays the ¬ symbol. Please help!

pragraph.Inlines.Add(new Span(FormattingSymbolLayoutBox.LINE_BREAK + "Some more text after the line break in the same paragraph");

Hi Doug,

In Q1 2015 we introduced a new Break element into the model of RadDocument. With the current version of RadRichTextBox, if you insert a line break symbol ("¬") or a page break symbol ("◊"), a break will not be inserted in the document. You can use the Break class, which is described in our documentation.

All the changes introduced in our controls are listed in the Changes and Backward Compatibility section for the control.

Hope this helps.

Using the 'Break' class indeed solves the problem, thanks.

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.

Hello Kalpa,

Could you please open a separate support thread in WordsProcessing forum? I can see that you already initiated a discussion here, if this is sufficient, we can continue the conversation there.
