If you have multiple controls that use autocomplete, a reasonably elegant solution is to retrieve the widget attached to the control at the last moment and modify its CSS:

$(document).ready(function() {
    $("input#Foo").autocomplete({
        source: source
    });
    $("input#Bar").autocomplete({
        source: source,
        open: function(event, ui) {
            $(this).autocomplete("widget").css({
                "width": 400
            });
        }
    });
});

As mentioned above, the width of autocomplete list is calculated at the very last moment hence you must modify it in the open event.
