RadDocument WPF - How to programatically create horizontal line?

[C]

How can I create a horizontal line similar to what is supported in Word in C# code programmatically without ever showing a RichTextBox control on screen.  We are using RadDocument to output read-only report data.

Also,  how can I do this without messing up the font before and after the table?  The fonts get reduced in size just before and after the table.

internal static void AddHorizontalLine(Section sec, RadDocument doc, double widthInches)
{
    //insert a horizontal line - table with 1 row and column - with a top border line and a table height of a few pixels
          
    Table t = new Table() {PreferredWidth = new TableWidthUnit(TableWidthUnitType.Fixed, Unit.InchToDip(widthInches)) };
    Border noBorder = new Border(BorderStyle.None);
    t.Borders = new TableBorders(noBorder, new Border(BorderStyle.Single), noBorder, noBorder);
    TableRow row = new TableRow();
    row.Height = 2.0;

TableCell cell = new TableCell();
cell.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 100.0);

Paragraph par = new Paragraph();
par.FontSize = 2;
par.Inlines.Add(new Span(" "));
cell.Blocks.Add(par);
row.Cells.Add(cell);

t.Rows.Add(row);

sec.Blocks.Add(t);

//We need to re-measure and re-layout the document after modifying the blocks, inlines, children and properties to format the output correctly. The fonts will be off if this is not done.
//doc.MeasureAndArrangeInDefaultSize(); //causes formatting problems in TOC
}

I've seen these two similar questions.

Hi,

Please find attached a simple example demonstrating how you can mimic a horizontal line in RadRichTextBox. Please note that tables in the context of RadDocument need to be surrounded by paragraphs.

As to your comment about the font size prior and after table, we are unaware of a reason for such behavior unless you've explicitly specified the font size needs to be small. If you are still experiencing this issue please provide more details on your setup or send us a sample application.

I hope this is useful.
