How to: Make a TextBox Control Read-Only

This example shows how to configure a xref:System.Windows.Controls.TextBox control to not allow user input or modification.

Example

To prevent users from modifying the contents of a xref:System.Windows.Controls.TextBox control, set the xref:System.Windows.Controls.Primitives.TextBoxBase.IsReadOnly%2A attribute to true.

[!code-xamlTextBox_MiscCode#_ReadOnlyTextBoxXAML]

The xref:System.Windows.Controls.Primitives.TextBoxBase.IsReadOnly%2A attribute affects user input only; it does not affect text set in the Extensible Application Markup Language (XAML) description of a xref:System.Windows.Controls.TextBox control, or text set programmatically through the xref:System.Windows.Controls.TextBox.Text%2A property.

The default value of xref:System.Windows.Controls.Primitives.TextBoxBase.IsReadOnly%2A is false.
