    I use RadRichTextBox and HtmlDataProvider like this

    <telhtml:HtmlDataProvider x:Name="htmlDataProvider"
                    Html="{Binding HtmlContent, Mode=TwoWay}"
                    RichTextBox="{Binding ElementName=HTMLRichTextBox}" />
    <telerik:RadRichTextBox x:Name="HTMLRichTextBox"
                    ScrollViewer.VerticalScrollBarVisibility="Auto" />

    When a user is typing, and presses "Enter" between the lines created by a large distance equal to one line. I looked in the "ViewModel" on the property HtmlContent, there is a symbol between the words </ p> (see example below)

        <p class="p_E2968D9D">
        <span class="s_E2968D9D">Hello world!</span>
        <p class="p_E2968D9D">
        <span class="s_E2968D9D">The world is mine ...</span>

    How do I fix this? As there was no distance between the lines?

    When the user presses enter, RadRichTextBox (and Word too) creates a new paragraph. By default, paragraphs have spacing between them. In order to avoid spacing, users must press Shift+Enter, which enters a line break. If you would like to have multiple paragraphs, but without spacing, you can set the SpacingAfter and SpacingBefore properties of existing paragraphs to 0 and ParagraphDefaultSpacingBefore and ParagraphDefaultSpacingAfter of RadDocument to 0.
    Let us know if that doesn't work for you.

    Hello Ivailo Karamanolev!
    Thank you very much for answer. I waited 4 days and was not hoping for an answer!
    It works!

    I took the DocumentArranged event (calls all the time, but suitable)
    private void HTMLRichTextBox_OnDocumentArranged(object sender, EventArgs e)
        foreach (Paragraph paragraph in ((RadRichTextBox) sender).Document.EnumerateChildrenOfType<Paragraph>())
            paragraph.SpacingAfter = 0;
            paragraph.SpacingBefore = 0;

     And I changed my RichText
    <telerik:RadRichTextBox x:Name="HTMLRichTextBox" DocumentArranged="HTMLRichTextBox_OnDocumentArranged" >
        <telerik:RadDocument ParagraphDefaultSpacingBefore="0" ParagraphDefaultSpacingAfter="0" />

    Differences between the Enter and Shift + Enter - almost no
