UpdatePanel doesn't trigger when enter is pressed
<p>I have a panel with some text boxes and a submit button, and an updatepanel that is set to trigger when the button is pressed.</p>

<p>If I press the button, it works as normal. However if I press enter on a control, it posts back the entire page.</p>

<p>I set the button as the default button in the panel, but it still posts back the entire page. Any ideas?</p>
