Make WPF textbox as cut, copy and paste restricted

Question

How can I make a WPF textbox cut, copy and paste restricted?

Answer 1

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

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;
     }
}
