You should change your button from ActionLink to a submit button like this
@Html.ActionLink("Submit", "All");
By
<input type="submit" value="submit"/>
Also change your Action to recieve the data by post
[HttpPost]
public ActionResult All(Speaker model)
{
return View(database.Speakers.FirstOrDefault());
}
