Does Validator.SetFocusOnError work without a postback?
<p>I have an ASP.net page with a RegexValidator.  The RegexValidator successfully displays my validation error text when a user types a value out of range and navigates (tabs) off of the control.  At that point, it doesn't set the focus to that control, even though I have SetFocusOnError="true".</p>

<p>The focus does appear to be set when I click a button on that page.  </p>

<p>Is focus supposed to be set as soon as the javascript detects on issue?</p>
