查看数据不保存在数据库Asp.net MVC 4中

Question

我想保存我的View类数据但是我点击创建按钮它不保存在数据库中请帮助我解决这个问题，如果有人知道原因。谢谢。

我的观点

@model EmpiteHrSystem.Models.tblEmployee
@{
ViewBag.Title = "Create";}

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
@Html.HiddenFor(model => model.EmployeeId)
@Html.HiddenFor(model => model.DepartmentId)
<input type="submit" value="Create" class="linkButton"/> 
@Html.ActionLink("Cancel", "Index",null,new { @class = "linkButton" })

 @Html.DropDownList("TitleOptions","Select Department")
 @Html.ValidationMessageFor(model => model.Title)

我的控制器类

public ActionResult Create()
{
   ViewBag.TitleOptions = new SelectList(db.tblEmployees, "EmployeeId", "Title","123M");
   ViewBag.DivisionOptions = new SelectList(db.tblDepartments, "DepartmentId", "DepartmentType");
   ViewBag.PositionOptions = new SelectList(db.tblEmployees, "EmployeeId", "Position");
   ViewBag.OfficeOptions = new SelectList(db.tblDepartments, "DepartmentId", "DepartmentLocation");
   //ViewBag.Position = new SelectList(db.tblDepartments, "DepartmentId", "DepartmentType", "123M");
   return View();
}

//
// POST: /Employee/Create

[HttpPost]
public ActionResult Create(tblEmployee tblemployee)
{
    if (ModelState.IsValid)
    {
       try
       {
           //db.Entry(tblemployee).State = EntityState.Added;
           db.tblEmployees.Add(tblemployee);
           db.SaveChanges();
       }
       catch (ArgumentException ae)
       {
           ModelState.AddModelError("", ae.Message);
       }
       return RedirectToAction("Index");
    }

    ViewBag.DepartmentId = new SelectList(db.tblDepartments, "DepartmentId", "DepartmentType", tblemployee.DepartmentId);

    return View(tblemployee);
}

    //[HiddenInput(DisplayValue = false)]
    //[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int EmployeeId { get; set; }
