#382 – Persisting RichTextBox Contents as XAML

You can use the Save method of a TextRange object to save the contents of a RichTextBox control.

In the example below, I enter some formatted text into a RichTextBox and then click the Save button.

Here’s the code that does the save behavior.

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            TextRange allText = new TextRange(rtfMain.Document.ContentStart, rtfMain.Document.ContentEnd);

            FileStream stream = new FileStream(@"D:\AboutMyDog.xaml", FileMode.Create);

            allText.Save(stream, DataFormats.Xaml);

            if (stream != null)
                stream.Close();
        }

The resulting XAML file consists of an outer Section element that in turn contains multiple Paragraph elements.

    <Paragraph>
        <Run FontStyle="Italic">Kirby</Run>
        <Run> is a </Run>
        <Run FontWeight="Bold">Border Collie</Run>
        <Run>.</Run>
    </Paragraph>
    <Paragraph>
        <Run FontStyle="Italic">Jack</Run>
        <Run> is a </Run>
        <Run FontWeight="Bold">Jack Russell Terrier</Run>
        <Run>.</Run>
    </Paragraph>
