I have a problem that is haunting me for a while. I tried some solutions but they didn\'t worked.

I think you will be better off when formatting when the user moves to the next control, e.g. like below. Otherwise it will be very confusing as the text will change itself as the user is typing:

    private void textBox1_Leave(object sender, EventArgs e)
    {
        Double value;
        if (Double.TryParse(textBox1.Text, out value))
            textBox1.Text = String.Format(System.Globalization.CultureInfo.CurrentCulture, "{0:C2}", value);
        else
            textBox1.Text = String.Empty;
    }
