```
richtextbox1.SelectionCharOffset =
-1 * ( Convert.ToInt32(R223.Txt_Space_Before.Text) * 100);

or
```
richtextbox1.SelectionCharOffset =

can be used for Line Spacing.
This is the only way you can have line height spacing. | I know this question was posted before I even started coding but I found that simply setting `ShowSelectedMargin` to `true` did the trick |
325,075 | I am using a RichTextBox in WPF, and am trying to set the default paragraph spacing to 0 (so that there is no paragraph spacing). While I could do this in XAML, I would like to achieve it programmatically if possible. Any ideas? | 2008/11/28 | [

] | Using Line Height
```
RichTextBox rtb = new RichTextBox();
Paragraph p = rtb.Document.Blocks.FirstBlock as Paragraph;
p.LineHeight = 10;
``` | For me on VS2017 in WPF works this:
```
<RichTextBox HorizontalAlignment="Left" Height="126" Margin="10,280,0,0" VerticalAlignment="Top" Width="343" FontSize="14" Block.LineHeight="2"/>
```
The key is **Block.LineHeight="2"**
You can found this also in Properties view but you can't change below 6px from there. |
