I think it would be even better to not even allow users to type in other than numbers if the textbox has to contain a number only.
Here is a little function for you which checks if the keys the user pressed are numeric characters and not allowing other characters to be inserted into the checkbox:

Code: Select all
private void Checkifnumber(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;
      }
}


Just attach a Keypress Event to the textboxes of interest and call the above function.



Thanks works great, I modified slightly not to allow any decimals just numbers.
