I have lot of textbox in my winform. maybe 20 to 30 textbox.
and I need all texbox have numerical only when typing.



I use keypress event per textbox to handle the numerical only(code below)



 if (!char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar) && (e.KeyChar != '.'))

            {

                e.Handled = true;

            }

            // only allow one decimal point

            if ((e.KeyChar == '.') && ((sender as TextBox).Text.IndexOf('.') > -1))

            {

                e.Handled = true;

            }


is there possible way to inherit all textboxes in just 1 keypress event?

Implement the keypress event for only one textbox.



Then select another text box and go to keypress event and select the method you already implemented.
