XMLNS for XAML:
member IsUndoEnabled : bool with get, set
< object IsUndoEnabled = " bool " ... />
System .Boolean if undo support is enabled; otherwise, true . The default value is false . true

The following example demonstrates how to use the
property in Extensible Application Markup Language (XAML). IsUndoEnabled
< TextBox TextWrapping = " Wrap "
Name = " myTextBox "
Width = " 500 "
Height = " 200 "
AcceptsReturn = " True "
IsUndoEnabled = " True "
VerticalScrollBarVisibility = " Visible "
HorizontalScrollBarVisibility = " Auto "
Margin = " 25 " >
