document.LoadDocument("Documents//Grimm.docx", DevExpress.XtraRichEdit.DocumentFormat.OpenXml);
document.Unit = DevExpress.Office.DocumentUnit.Inch;
Section sec = document.Sections[0];
sec.LineNumbering.CountBy = 2;
sec.LineNumbering.Start = 1;
sec.LineNumbering.Distance = 0.25f;
sec.LineNumbering.RestartType = LineNumberingRestart.NewSection;
