HI,

To disable Copy/Cut/Paste from a TextBox you can detect when their KeyBindings are pressed to avoid executing the corresponding commands:
public class DisableCopyCutPaste: MonoBehaviour
{
    void Start()
    {
        var gui = GetComponent<NoesisGUIPanel>();
        var content = gui.GetContent();

        var txt = (TextBox)content.FindName("myTextBox");
        txt.PreviewKeyDown += txt_PreviewKeyDown;
    }

    void txt_PreviewKeyDown(object sender, KeyEventArgs e)
    {
        Keyboard kb = ((UIElement)sender).GetKeyboard();
        bool ctrl = kb.IsKeyDown(Key.Control);
        bool shift = kb.IsKeyDown(Key.Shift);

        if ((ctrl && e.Key == Key.C) || (ctrl && e.Key == Key.Insert) ||
            (ctrl && e.Key == Key.X) || (shift && e.Key == Key.Delete) ||
            (ctrl && e.Key == Key.V) || (shift && e.Key == Key.Insert))
        {
            e.Handled = true;
        }
    }
}

        {
            e.Handled = true;
        }
    }
}
