How do I change RichTextBox paragraph spacing?

Question

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?

Answer 1

Using Line Height

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

Answer 2

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

p.Margin = new Thickness(0);

Answer 3

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>

Answer 4

I'd like to do that by code for all the paragraphs of my richtextbox, is it possible ?

Answer 5

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

                       XYZ

                        <LineBreak></LineBreak>
                    </Paragraph>
</RichTextBox>

Answer 6

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
