Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Public Property IsReadOnly As Boolean

Property Value
Type: System.Boolean
true if the text box is read-only; otherwise, false. The default is false.
Remarks
Dependency property identifier field: IsReadOnlyProperty.
If the text box is read-only, no user input or edits are allowed, but programmatic changes can be made. The user can still select text, and the cursor still appears. The KeyUp and KeyDown events are marked as handled.
Examples
The following code snippet displays a read-only text box.
<TextBlock Margin="20,20,0,0" Text="Read Only TextBox"/>
<TextBox x:Name="ReadOnlyTB" IsReadOnly="True" HorizontalAlignment="Left" Margin="20,5,0,0" Height="35" Width="200" />
