You can see the different solutions form this link:

@using (Html.BeginForm("Method", "YourController")) {

@Html.DropDownList("Id", ViewBag.DropDownCollection as SelectList, "--pick--", new {
    title = "Pick Batch",
    onchange = "submit();"
});

}

ActionResult

public ActionResult Method(string Id)
{
 //do the logic here
}
