title: ASP.NET enter key and form submit with no javascript
body: <p>I have a form that I want to submit when the user presses the enter key. It works fine in Firefox, but not in IE. It is basically the same issue as this, except that I am not allowed to use any JavaScript:

  <p>Unfortunately it looks like ASP.NET uses JavaScript to process the button postback. Is there a way around this issue that doesn't rely on JavaScript?</p>
