all i want is to insert a simple Bulleted List inside RadRichtextBox.
Or basically, I want to show few texts in bullets. 
How do I do that?

BulletedList list = new BulletedList(this.radRichTextBox1.Document);
foreach (string item in TableOfContent)
{
         Paragraph p = new Paragraph();
         p.Inlines.Add(new Span(item));
         list.AddParagraph(p);
         ListItemInfo li = new ListItemInfo(list, p, 1);
}

I tried above code and also this.
Nothing works, not even my text appears inside the richtextbox upon run.
Please help.

Manish, I do not know if you have been able to resolve this issue or not, but as I am having a similar problem I wanted to add on.  In my case I have been able to format my desired text into bulleted list items - however, I cannot seem to get them to appear WHERE I want them to be.  Using richTextBox.Insert will put the inserted text to the beginning of the document (or rather, after other inserted items prior).


In my case, what I need is to have the items inserted into the current section of the document that I am working in - which I am not able to do so far.

Either way - here is the code that I used to insert the bulleted list:



public void AddSummarySection()
        {
            Section section = new Section();
 
            Paragraph titleParagraph = new Paragraph();
            Span titleSpan = new Span();
            titleSpan.Text = "Current Status Highlights / Executive Summary" + Environment.NewLine;
            titleParagraph.Inlines.Add(titleSpan);
             
            Span span2 = new Span();
            Span span3 = new Span();
 
            span2.Text = "Wins and Updates:" + Environment.NewLine;
            span3.Text = "Issues and Risks:" + Environment.NewLine;
            //titleParagraph.Inlines.Add(span2);
            //titleParagraph.Inlines.Add(span3);
 
            section.Blocks.Add(titleParagraph);
            this.rtbDocument.Document.Sections.Add(section);
 
            rtbDocument.Document.Selection.Clear();
            rtbDocument.Insert(span2.Text);
            rtbDocument.Insert(span3.Text);
 
            DocumentTextSearch search = new DocumentTextSearch(rtbDocument.Document);
            TextRange range = search.Find(span2.Text);
            TextRange range2 = search.Find(span3.Text);
 
            if (range != null && range2 != null)
            {
                this.rtbDocument.Document.Selection.AddSelectionStart(range.StartPosition);
                this.rtbDocument.Document.Selection.AddSelectionEnd(range2.EndPosition);
                this.rtbDocument.ChangeListStyle(DefaultListStyles.Bulleted);
            }
}

Hello Justin,

Thank you for contacting Telerik Support.

In order to insert a bulleted list you will need to use the DocumentList class which is usually used for such listings. A sample method which can be used follows:
private void AddBulletList(Section sectionToUse = null)
{
    DocumentList list = new DocumentList(DefaultListStyles.Bulleted, this.richTextBox.Document);
    Section section = sectionToUse ?? new Section();
 
    for (int i = 0; i < 3; i++)
    {
        Paragraph listItemParagraph = new Paragraph();
        Span listItemSpan = new Span("Bullet " + (i + 1));
        listItemParagraph.Inlines.Add(listItemSpan);
        list.AddParagraph(listItemParagraph);
        section.Blocks.Add(listItemParagraph);
    }
 
    if (sectionToUse == null)
    {
        this.richTextBox.Document.Sections.Add(section);
    }
}

This method suggests that either a section will be passed or if not a new one will be created. If you want to use it with the current Section you can use the following approach:
this.AddBulletList(this.richTextBox.Document.CaretPosition.GetCurrentSectionBox().AssociatedSection);

I hope you will find this helpful.

George
