jQuery autocomplete problem: how to handle 'Not in list' case
<p>Let me clarify: I'm using standard jQuery autocomplete plugin (bassistanse.de) and bind it to a KeyValueCollection serialized to JSON (ASP.NET MVC). All works fine, except I want to be able to notify user when he/she types in a value which isn't present in DB, i.e. value not in list.</p>

<p>What are possible ways of solving this?</p>

<p>Ideally, I would like to handle both 'first time error' and 'error after valid choice' cases.</p>

<p>Handling 'blur' event doesn't help, since user can click drop down item (effectively losing focus), and after that the selection immediately will have been made.</p>

<p>Thank you.</p>
