        <tbody>
            @for (int i = 0; i < Model.Count(); i++)
            {
                <tr>
                    <td>


                        <div class="icheck-primary">

                            <label for="ContractId">

                            </label>
                        </div>
                    </td>
                    <td>
                        @Html.DisplayFor(modeli => Model[i].Customer.Name)
                    </td>


                    <td>

                        <input type="number" step="0.01" class="form-control" id="@Model[i].ContractId"
                               value="" name="TxtPayout" max="" />

                    </td>


                    <td>

                        <input type="date" id="@Model[i].ContractId" value="@DateTime.Now.ToString("yyyy-MM-dd")" name="TxtDatePaid" class="form-control" />
                    </td>



                </tr>
            }
        </tbody>


    </table>
    <input type="submit" value="Update Record" class="btn  btn-primary" />
}

 

 My Controller [HttpPost]

 

public ActionResult Update_Record(System.Web.Mvc.FormCollection form)
      {


          string[] contid = form.GetValues("contId");
          decimal total = 0; // to get the total salaries
          int cnt = 0; //Count Affected Rows
          if(contid != null)
          {
              string[] payout = form.GetValues("TxtPayout");
              string[] datepaid = form.GetValues("TxtDatePaid");
              for(int i = 0; i < contid.Length; i++)
              {
                  decimal salary = Convert.ToDecimal(payout[i]);
                  DateTime dt = Convert.ToDateTime(datepaid[i]);
                  total += salary; //Convert.ToDecimal(payout[i]);
                  cnt++;
              }
              TempData["Message"] = string.Format("Successfully Updated with {0} record(s) affected Total Payout: {1}", cnt, total);

          }

          getContract();
          return View(ViewBag.gct);
      }
