protected override void OnKeyPress(KeyPressEventArgs e) { // Ignore all non-control and non-numeric key presses. if (! char .IsControl(e.KeyChar) && ! char .IsDigit(e.KeyChar)) { e.Handled = true ; } // Call the implementation in the base TextBox class, // which raises the KeyPress event. base .OnKeyPress(e); }
