RichTextBox with bulleting option

[Abisek]

Needed help in a Rich text box with bulleting option.
 
To achieve this  my code is 
 
<StackPanel Grid.Row="0" Orientation="Horizontal" x:Name="Stack">           
<telerikRibbonBar:RadButtonGroup>               
<telerikRibbonBar:RadRibbonToggleButton x:Name="Bullet" Click="Bullet_Click" Content="."/>            </telerikRibbonBar:RadButtonGroup> 
 </StackPanel>               
<telerik:RadRichTextBox x:Name="RTB" Height="300" Grid.Row="1" Width="600"/>
 
And in class file
 
private void Bullet_Click(object sender, RoutedEventArgs e)
        {
            RadDocument document = new RadDocument();
            document = RTB.Document.Selection.CreateDocumentFromSelection();
            RTB.Document.Selection.AnchorSelectionPositions();
            document = CreateDocumentWithMultiLevelList(document);
            RTB.Document = document;
        }
 
And
 
 
private RadDocument CreateDocumentWithMultiLevelList(RadDocument document)
        {
            Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();
 
            BulletedList bulletList = new BulletedList(document);
            bulletList.Style = DefaultListStyles.Numbered;
            foreach (Paragraph paragraph in document.EnumerateChildrenOfType<Paragraph>())
            {
                bulletList.AddParagraph(paragraph);
            }
           
            document.Sections.Add(section);
            return document;
        }
 
 
The problem is that my code is replacing not only the selected text but the entire content of the Rich text block with my formatted text. Can I replace only the selected content by my new bulleted content?

Hi Abisek,

The part of the document that is not selected is stripped, because you change the Document of RadRichTextBox to the newly created one.
If you want to add bullets to all selected paragraphs, you can invoke the following method, which operates on the selection:

RTB.ChangeListType(ListType.Bulleted);

You don't need to have any pre- or post-processing, anchoring the selection positions, etc.

I hope this helps.

Best wishes,
