This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.
The following example demonstrates how to use the derived TextBox object in Extensible Application Markup Language (XAML).
<TextBox TextWrapping="Wrap" Name="myTextBox" Width="500" Height="200" AcceptsReturn="True" IsUndoEnabled="True" VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Auto" Margin="25">
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.
