Examples
The following example demonstrates how to use the IsUndoEnabled property 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">
Remarks
Setting this property to false
clears the undo stack. Therefore, if you disable undo and then re-enable it, undo commands still do not work because the undo stack was emptied when you disabled undo.
