Gets or sets a value that indicates whether the text editing control is read-only to a user interacting with the control.
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
<object IsReadOnly="bool" .../>
Property Value
Type: System.Booleantrue if the contents of the text editing control are read-only to a user; otherwise, the contents of the text editing control can be modified by the user. The default value is false.
This example shows how to configure a TextBox control to not allow user input or modification.
To prevent users from modifying the contents of a TextBox control, set the IsReadOnly attribute to true.
<TextBox IsReadOnly="True" > The user may not modify the contents of this TextBox. </TextBox>
The IsReadOnly attribute affects user input only; it does not affect text set in the Extensible Application Markup Language (XAML) description of a TextBox control, or text set programmatically through the Text property.
The default value of IsReadOnly is false.
