Hi, so create 3 text box key press event like bellow

Try like

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
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;
}
}

Hi Vivek, In your form 4 form in screen shot. There are Name, PhoneNo,FaxNo and MobileNo.

Please confirm which text box are you validate accept only number. ?

I thnk this3 fields PhoneNo,FaxNo and MobileNo. So pls created every textboxt contains keypress event. Are you do it same or not?
