title: Pressing enter on any textbox invokes my Save button click event?
body: <p>I have a standard asp.net webform with multiple textboxes (Autopostback=False) on it and a Save button.<br>
  Pressing ENTER while in any textbox is causing the server side click event of the Save button to be invoked.  If I break and look at the call stack, the click event is the only event listed. I do not have a default button set for the form.
  If I put another button above the save button, then it gets its click event invoked on any press of enter on a textbox.</p>
  
  <p>Any ideas why this is happening, and how to get it to stop?</p>
