Counting List Level in RadRichTextBox

[Ashrul]

hi, i m ashrul,

i m working in RadRichTextBox right now, i want to ask about liststyle, how we can count listlevel dinamically when user typing ang using listlevel..

here my snippet:

 

  private void Button_Click(object sender, RoutedEventArgs e)
        {

            RadDocument document = this.editor.Document;
            RadDocumentEditor editor = new RadDocumentEditor(document);
            ListStyle listStyle = new ListStyle();
            ListLevelStyle listLevel = new ListLevelStyle();

            MessageBox.Show(listLevel.ToString());
        }

 

 

thanks in advance

Hi,

I am not completely sure I understand what you would like to do. If you want to find what is the level of the current text the user is on you can do it like this:

Paragraph paragraph = document.CaretPosition.GetCurrentParagraphBox().AssociatedParagraph;
int level = paragraph.ListLevel;

MessageBox.Show(level.ToString());

On the other hand, if you want to find the deepest level of the list, you can iterate the paragraphs like this:

int maxLevel = 0;

foreach (Paragraph par in document.EnumerateChildrenOfType<Paragraph>())
{
    int level = par.ListLevel;

    if (level > maxLevel)
    {
        maxLevel = level;
    }
}

MessageBox.Show(maxLevel.ToString());

I hope this answers your question. Please, let me know if you had something else in mind.
