Use the code for inserting the code:

{

Telerik.Windows.Documents.Flow.Model.RadFlowDocument contentDocument = GetDocument("Content.rtf");
InsertDocumentOptions options = new InsertDocumentOptions();

options.InsertLastParagraphMarker = true;
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(templateDocument);
editor.InsertDocument(contentDocument, options);
string mergedDocumentFilePath ="MergeDocumentsWithWordsProcessing.rtf";
File.Delete(mergedDocumentFilePath);

}
private static Telerik.Windows.Documents.Flow.Model.RadFlowDocument GetDocument(string rtfFilePath)

string rtfText = rtfExporter.Export(doc);
File.WriteAllText(filename, rtfText);
Process.Start(filename);
}
Observed result: The After spacing is reset
Expected result: keep the style settings from the original documents.
Converting some DocX files to PDF format with page numbering leads to incorrect formatting in the exported PDF:
Input DocX:
Output PDF:
Original DOCX document:
Exported DOCX document:

using (Stream input = File.OpenRead("PT1987 VU22888 Moodle Specification List [2024032716].docx"))
{
document = docXprovider.Import(input);

The following error occurs:
When exporting a DOCX file to PDF format, the following error message occurs:
PdfFormatProvider: Table cells are exported with the wrong width when the table is nested in another table and the cells of the nested one have a preferred width set to 100%.
Workaround: Clear the cell PreferredWidth property.
PdfFormatProvider: Tab stop distance different from the default is not exported correctly.
Workaround: Use spaces instead.
Styles with names only different in spaces are treated as one.

StackOverflowException when importing a document with style based on itself.
Use the following code to strip the faulty "based on" definition from the RTF:
RtfFormatProvider provider = new RtfFormatProvider();
var rtf = File.ReadAllText(ofd.FileName);
rtf = this.ReplaceSelfBasedOnStyle(rtf);
this.flowDocument = provider.Import(rtf);
...
private string ReplaceSelfBasedOnStyle(string rtf)
{
string pattern = @"{[\n]*\\s[0-9]+[^;]* \\\w* (Normal);}";
var matches = Regex.Matches(rtf, pattern);
foreach (Match match in matches)
{
string oldValue = match.Value;
string newValue = oldValue.Replace(@"\sbasedon0 ", string.Empty);
rtf = rtf.Replace(oldValue, newValue);
}
return rtf;
}
When a document containing a field without a separator is inserted using the RadFlowDocumentEditor.InsertDocument(*) method, the following error is thrown:
