The following example demonstrates how to use the derived TextBox object in Extensible Application Markup Language (XAML).

The following example demonstrates how to use the derived RichTextBox object in code.
RichTextBox richTextBox = new RichTextBox(); richTextBox.PreviewMouseUp += MouseUpHandler; richTextBox.PreviewMouseDown += MouseDownHandler; // Note: Event listeners can also be added using the AddHandler // method.
