Answer 1

You could also try this way, with accept decimals character

    private void Column1_KeyPress(object sender, KeyPressEventArgs e) 
    {
        //allow number, backspace and dot
        if (!(char.IsDigit(e.KeyChar) || e.KeyChar == (char)Keys.Back || e.KeyChar == '.'))
        {
            e.Handled = true;

        }
        //allow only one dot
        if (e.KeyChar == '.' && (sender as TextBox).Text.Contains("."))
        {
            e.Handled = true;

        }
    }
