George Shepherd's Windows Forms FAQ 27.1 works fine for TextBox controls. I tried the same with a MaskedTextBox control. [C#] public class MyTextBox : MaskedTextBox { protected override void OnKeyPress(KeyPressEventArgs e) { if(e.KeyChar == (char) 13) e.Handled = true; else base.OnKeyPress (e); } } The beep is elimiated however the Mask Property behaves erratically. Does anyone know of an explanation for this?
