How do I change RichTextBox paragraph spacing?

WpfRichtextbox

Wpf Problem Overview

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?

Solution 1 - Wpf

I did it with style (pun indented)

<RichTextBox  Margin="0,51,0,0" Name="mainTextBox" >
        <RichTextBox.Resources>
            <Style TargetType="{x:Type Paragraph}">
                <Setter Property="Margin" Value="0"/>
            </Style>
        </RichTextBox.Resources>
    </RichTextBox>

Solution 2 - Wpf

Using Line Height

RichTextBox rtb = new RichTextBox();    
Paragraph p = rtb.Document.Blocks.FirstBlock as Paragraph;    
p.LineHeight = 10;

Solution 3 - Wpf

Close, so you got the points. Actually it turned out to be setting the margin,

p.Margin = new Thickness(0);

Solution 4 - Wpf

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.

Solution 5 - Wpf

RichTextBox rtb = new RichTextBox();
rtb.SetValue(Paragraph.LineHeightProperty, 1.0);

Solution 6 - Wpf

<RichTextBox  Height="250" Width="500" VerticalScrollBarVisibility="Auto" TextWrapping="Wrap" IsReadOnly="True" >
    <Paragraph>
        XYZ
        <LineBreak />
    </Paragraph>
</RichTextBox>

Solution 7 - Wpf

In C# 2008 WAP

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

or

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

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
