title: make nullable Numeric up down c#
body: <p>Is there anyway to remove the 0 from the default value of 0 on the numeric up down tool in c#? I need to default to null "" if the user does not set the numeric updown tool, as it always will pass a 0 through when saved is clicked. I have tried this but with no joy </p>
  
  <pre><code>private void nud_HouseNumber_Validated(object sender, EventArgs e)
  {    
      if (nud_HouseNumber.Text == "0")
      {
          nud_HouseNumber.Text = "" ;
          return;
      }
  }
  </code></pre>
