How do I change RichTextBox paragraph spacing?

Tag: ,

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?

    Using Line Height

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

    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>

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

    p.Margin = new Thickness(0);

    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.

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