How do I associate a selected value from a drop down list to the row id within a table?

DropDownList

MVC5

I am trying to build an application that will allow a teacher to enter class attendance within a web application. I have gotten it to display the students in the specified class along with a drop down list that is populated with the possible attendance choices. When the instructor clicks the save attendance button, the returned values is just a list of all the chosen values like attend_detail=PRESENT&attend_detail=PRESENT&attend_detail=ABSENT&attend_detail=TARDY&attend_detail=ABSENT&attend_detail=PRESENT&attend_detail=PRESENT&attend_detail=UNEX+AB. It has each value selected for each student, but I have no way to know who had which status.

Here is the View that shows the students.

@model IEnumerable<RLCAttendanceWebAppNoOauth.Models.student_list>
@{
    ViewBag.Title = "ClassList";
}

<h2>ClassList</h2>
<p>@ViewBag.attend_date</p>
<p>@ViewBag.year</p>
<p>@ViewBag.term</p>
@using (Html.BeginForm("SaveAttendance", "Schedule", FormMethod.Post))
{
    <table class="table">
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.ID)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.LAST_NAME)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.FIRST_NAME)
            </th>
            <th></th>
        </tr>
        @foreach (var item in Model)
        {
            <tr>
                <td>
                    @Html.DisplayFor(modelItem => item.ID)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.LAST_NAME)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.FIRST_NAME)
                </td>
                <td>                
                    <p>
                        @Html.DropDownList("attend_detail", null, "", new { id = item.ID }) 
                    </p>                
                </td>
            </tr>
        }
    </table>
<input type="submit" value="Save Attendance" />
}

Here is the Model for student_list.

using System;
using System.Collections.Generic;

public partial class student_list
{
    public string LAST_NAME { get; set; }
    public string FIRST_NAME { get; set; }
    public Nullable<System.DateTime> CHANGE_DATE { get; set; }
    public string ACADEMIC_YEAR { get; set; }
    public string ACADEMIC_TERM { get; set; }
    public string ACADEMIC_SESSION { get; set; }
    public string EVENT_ID { get; set; }
    public string SECTION { get; set; }
    public string ID { get; set; }
}

Here is the code from the controller that lists the students in the class.

public ActionResult ClassList(DateTime Attend_Date)
{
    Session["attend_date"] = Attend_Date.ToShortDateString();
    sp_rlc_lti_student_list_Result model = new sp_rlc_lti_student_list_Result();
    var attend_detail = db.attend_detail
        .OrderBy(q => q.CODE_VALUE_KEY)
        .ToDictionary(q => q.CODE_VALUE_KEY, q => q.LONG_DESC);
    ViewBag.attend_detail = new SelectList(attend_detail, "Key", "Value");

    var year = Session["year"].ToString();
    var term = Session["term"].ToString();
    var event_id = Session["course_id"].ToString();
    var section = Session["section"].ToString();
    var classListQry = from c in db.student_list
                       where c.ACADEMIC_YEAR == year
                           & c.ACADEMIC_TERM == term
                           & c.EVENT_ID == event_id 
                           & c.SECTION == section
                           & c.CHANGE_DATE > Attend_Date
                       select c;
    return View(classListQry);
}

Here is the code from the controller that executes when the save button is clicked.

public ActionResult SaveAttendance()
{
    ViewBag.message = "The attendance for the class was saved for: " + Session["attend_date"].ToString();
    return View();
}

When the save button is clicked I need to be able to push the selected attendance for each student back to a database. The student_list model includes the student's unique ID, I just have not found a way to link the value selected in the drop down list to the student it was selected for.

What I have tried:

I am not exactly sure what to try at this point. I have looked for solutions online and either they are not out there or I am not asking the question correctly.
