Line Spacing after Enter in RadRichTextBox

[Ramesh]

I did all I can Still I cannot take away the line spacing after hitting  "Enter", I could not get it working  (looks like the DocumentInheritsDefaultStyleSettings  is interfering?)

I have uploaded a sample project (that tells the behavior) as well.

 

Please find the code I used below.

                                <telerik:RadRichTextBox x:Name="custNotesRichTextBox"
                                                        Grid.Row="0"
                                                        DocumentInheritsDefaultStyleSettings="True"                                                     
                                                        AcceptsTab="True"
                                                        AcceptsReturn="True"                                                         
                                                        ScrollViewer.VerticalScrollBarVisibility="Auto"
                                                        HorizontalScrollBarVisibility="Hidden"                                                        
                                                        IsSpellCheckingEnabled="True"
                                                        Language="en-US"
                                                        IsContextMenuEnabled="True"                                                        
                                                        Margin="0"
                                                        VerticalScrollBarVisibility="Hidden">
                                    <telerik:RadRichTextBox.Document>
                                    <telerik:RadDocument LineSpacing="0" LineSpacingType="AtLeast" ParagraphDefaultSpacingAfter="0" ParagraphDefaultSpacingBefore="0" >
                                        <telerik:Section>
                                                <telerik:Paragraph LineSpacing="0" LineSpacingType="AtLeast" SpacingBefore="0" SpacingAfter="0" AutomaticSpacingBefore="False" AutomaticSpacingAfter="False" >
                                                <telerik:Span  Text=" "/>
                                            </telerik:Paragraph>
                                        </telerik:Section>
                                    </telerik:RadDocument>
                                    </telerik:RadRichTextBox.Document>
                                    </telerik:RadRichTextBox>

Hi Ramesh,

When the document is changed the styles are reset as well, so are the settings set at design time. You will need to change the normal style each time the document is changed. For example, you can use the DocumentChanged event and set the styles there:

public MainWindow()
{
    InitializeComponent();
    radRichTextBox.DocumentChanged += RadRichTextBox_DocumentChanged;
}

private void RadRichTextBox_DocumentChanged(object sender, EventArgs e)
{
    StyleDefinition normalStyle = this.radRichTextBox.Document.StyleRepository[RadDocumentDefaultStyles.NormalStyleName];
    normalStyle.ParagraphProperties.SpacingAfter = 0;
    normalStyle.ParagraphProperties.SpacingBefore = 0;
    normalStyle.ParagraphProperties.AutomaticSpacingAfter = false;
    normalStyle.ParagraphProperties.AutomaticSpacingBefore = false;
    normalStyle.ParagraphProperties.LineSpacing = 0;
    normalStyle.ParagraphProperties.LineSpacingType = LineSpacingType.AtLeast;
}

Let me know if I can assist you further.

Hi Dimitar, this worked well! Thanks!

[Dimitar]

Hi Ramesh,

You need to set the SpacingAfter property to 0. Here is how you can get the normal style and set this property: 

StyleDefinition normalStyle = this.custNotesRichTextBox.Document.StyleRepository[RadDocumentDefaultStyles.NormalStyleName]; 
normalStyle.ParagraphProperties.SpacingAfter = 0; 

I hope this helps. Should you have any other questions do not hesitate to ask.

HI Dimitar, Thanks that worked, after adding few more lines to it, as below.

normalStyle.ParagraphProperties.SpacingAfter = 0;
normalStyle.ParagraphProperties.SpacingBefore = 0;
normalStyle.ParagraphProperties.AutomaticSpacingAfter = false;
normalStyle.ParagraphProperties.AutomaticSpacingBefore = false;
normalStyle.ParagraphProperties.LineSpacing = 0;
normalStyle.ParagraphProperties.LineSpacingType = LineSpacingType.AtLeast

But am curious why it didn't take the setting from the designer, and requiring us to manipulate the normal style is a question.

1) Hi Dimitar, When I try to bind the text from the code behind, again I get spacing. How Can avoid spacing when I bind text to the richtext control from code behind. Please note am binding using the MVVM pattern.

2)Also, the above code sometimes work and the next time , when I launch the textbox, from a different item in the grid, the style is not reflected. Not sure why can you explain.
