Using MVC 3, LINQ TO SQL, c#

@model IEnumerable<GetEmployeeEditDetails_SpResult>
          
@{
    var Item = Model.FirstOrDefault();
 }
           
<style type="text/css">

</style>
<div>
@using (Html.BeginForm("EditEmployee", "Home", FormMethod.Get))

  <label id="lblApproved" class="editEmp_label">Overtime Approval</label>
  <input type="CheckBox"  name="Approval" value=@Item.OvertimeApproved />
  <br />
  
  
}

       {
           if (!String.IsNullOrEmpty(Session["Admin"] as string))
           {
               int? EmplId = Convert.ToInt32(Session["EmpEdit"]);
               IEnumerable<GetEmployeeEditDetails_SpResult> EmployeeValues = DataContext.GetEmployeeEditDetails_Sp(EmplId).ToList();
               var DepNames = (from n in DataContext.HrDepts select new { n.DeptID, n.DeptName }).Distinct();
               ViewData["DeptID"] = new SelectList(DepNames, "DeptID", "DeptName");
               var ShiftNames = (from n in DataContext.AtdShifts select new { n.ShiftId, n.ShiftName }).Distinct();
               ViewData["ShiftId"] = new SelectList(ShiftNames, "ShiftId", "ShiftName", new select);
