Make WPF textbox as cut, copy and paste restricted

Cut, Copy and Paste are the common commands used any application,

<TextBox CommandManager.PreviewExecuted="textBox_PreviewExecuted"/>

in above textbox code we can restrict these commands in PrviewExecuted event of CommandManager Class

and in code behind add below code and your job is done

private void textBox_PreviewExecuted(object sender, ExecutedRoutedEventArgs e)
{
if (e.Command == ApplicationCommands.Copy ||
e.Command == ApplicationCommands.Cut  ||
e.Command == ApplicationCommands.Paste)
{
e.Handled = true;
}
}
