TextBoxBase.IsUndoEnabled TextBoxBase.IsUndoEnabled TextBoxBase.IsUndoEnabled TextBoxBase.IsUndoEnabled Property

Definition

Gets or sets a value that indicates whether undo support is enabled for the text-editing control.

public:
 property bool IsUndoEnabled { bool get(); void set(bool value); };
public bool IsUndoEnabled { get; set; }
member this.IsUndoEnabled : bool with get, set
Public Property IsUndoEnabled As Boolean

Property Value

true if undo support is enabled; otherwise, false. The default value is true.

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.
