I am using LINQ TO SQL, MVC 3, asp.net C#
 
CODE:
 
Controller:
 
public ActionResult EditEmployee() 
        {
            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");
                return View(EmployeeValues);
            }
VIEW:
 
@using EmployeeAttendance_app.Models
@model IEnumerable<GetEmployeeEditDetails_SpResult>
          
@{
    var Item = Model.FirstOrDefault();
 }
           
<style type="text/css">
 
</style>
<div>
@using (Html.BeginForm("EditEmployee", "Home", FormMethod.Get))
{
  <label id="lblName" class="editEmp_label">Name</label>
  <input type="text" value= @Item.EmplName  name="EmpName" placeholder="Update Name" />
  <br />
  <label id="lblDept" class="editEmp_label">Department</label>
  @Html.DropDownList("DeptID", @Item.DeptName)
  <br />
  <label id="lblShift" class="editEmp_label">Shift</label>
  @Html.DropDownList("ShiftId", "Select Shift")
  <br />
  <label id="lblEntryDate" class="TxtBoxFrom editEmp_label">Entry Date</label>
  <input type="text" value= @Item.EntryDate class="TxtBoxTo" name="EntryDate" placeholder="Update Date"  />
  <br />
  <label id="lblSalary" class="editEmp_label">Salary</label>
  <input type="text" value= @Item.BasicSalary  name="Salary" placeholder="Update Salary"   />
  <br />
  <label id="lblEmail" class="editEmp_label">Email</label>
  <input type="text" value= @Item.EmailAdd  name="Email" placeholder="Update Email"   />
  <br />
  <br />
  <button type="submit" id="btnUpdate" class="button_AdminPanel" style="width:75px" name="btnSubmit">Update</button>  
  
}

推荐答案

你必须在页面加载中绑定下拉列表

you have to bind the dropdownlists in page load

@Html.CheckBox("Approval", @Convert.ToBoolean( @Item.OvertimeApproved))
