Add form values to Ajax.ActionLink

Question

How is it possible to get values from a Html form to an Ajax.ActionLink method like the example below. Instead of "id=Model.DinnerID" I need to get the values of two textboxes that is in a Html form block?

<%= Ajax.ActionLink( "RSVP for this event", "Register", "RSVP", new { id=Model.DinnerID }, new AjaxOptions { UpdateTargetId="rsvpmsg", OnSuccess="AnimateRSVPMessage" }) %>

Answer 1

set id with id of the textbox(something like this: {id="textboxId"})
