I am trying to submit when a dropdownlist changes by doing this

```
@using (Html.BeginForm("testAction", "FishingTrip"))
{
    @Html.DropDownListFor(x => x.Day, Model.Days,  new { onchange="this.form.submit();" })
}

```

This works fine but I am having problems (in other words don't know how) to get the option value on the server, can anybody help me with this ?

cheers
