In MVC you are not supposed to databind from the view in the way that you have. The data that you want to pass to the ActionLink method needs to be added to ViewData in your controller. Then in the view you retrieve it from ViewData:

<%= Html.ActionLink("My Edit Link", "Edit", "Message", new { id = ViewData["id"] }) %>
