title: Not able to capture Enter key in WinForms text box
body: <p>When the user is entering a number into a text box, I would like them to be able to press Enter and simulate pressing an Update button elsewhere on the form.  I have looked this up several places online, and this seems to be the code I want, but it's not working.  When data has been put in the text box and Enter is pressed, all I get is a ding.  What am I doing wrong? (Visual Studio 2008)</p>
  
  <pre><code>private void tbxMod_KeyDown(object sender, KeyEventArgs e)
  {
      if (e.KeyCode == Keys.Enter)
      {
          btnMod.PerformClick();
      }
  }
  </code></pre>
