当我运行谷歌浏览器这个应用程序这是给空格，后进入的值，然后preSS提交按钮，但是当我在IE8上运行这个它是在起步阶段本身给错误这样的.. ..

在行238未处理的异常，在功能code柱37
0x800a138f - 微软JScript运行时错误：'data.EmployeeDetails.EmployeeId'为空或不是对象

这是我的模型

 公共类TextBoxGrid
    {
        公共字符串EnteredValue {搞定;组; }
        公开名单＆LT; EmployeeDetails＆GT;雇员;
    }
    公共类ParentViewModel
    {
        公共EmployeeDetails EmployeeDetails {搞定;组; }
        公共TextBoxGrid TextBoxGrid {搞定;组; }
    }
    公共类EmployeeDetails
    {
        公共字符串雇员{搞定;组; }
        公共字符串经理ID {搞定;组; }
    }

这是我的控制器

 公共类EnterValues​​GridController：控制器

    }
    私人的IEnumerable＆LT; EmployeeDetails＆GT; GetOrders（）

    }
}

这是我的看法。

  @model KendoPratapSampleMVCApp.Models.ParentViewModel
@ {
    ViewBag.Title =指数;
}
@using（Html.BeginForm（PostValues​​，EnterValues​​Grid，FormMethod.Post））

     @ Html.TextBoxFor（M = GT; m.TextBoxGrid.EnteredValue）

        columns.Bound（S =＆GT; s.EmployeeDetails.ManagerId）.Filterable（假）.WIDTH（100）;
    }）
    .Filterable（）

        阿贾克斯（）
        .PageSize（20）
        .Read（读=＆GT; read.Action（Orders_Read，EnterValues​​Grid））
     ）
  ）
}

我不知道我在哪里做错了，你会暂建议在这一个任何想法..
非常感谢...，做我需要做的UI GRID我试图改变后的值的方法，任何改变......但因此未工作对我来说...

更新：
改TempData的查看背包

解决方案

嗨普拉塔普我刚刚更新code，

型号 

 公共类TextBoxGrid
    {
        公共字符串EnteredValue {搞定;组; }
        公开名单＆LT; EmployeeDetails＆GT;雇员;
    }
    公共类ParentViewModel
    {
        公共EmployeeDetails EmployeeDetails {搞定;组; }
        公共TextBoxGrid TextBoxGrid {搞定;组; }
    }
    公共类EmployeeDetails
    {
        公共字符串EnteredValue {搞定;组; }
        公共字符串雇员{搞定;组; }
        公共字符串经理ID {搞定;组; }
    }

HI I am stuck in getting data that i need to display in kendo UI GRID , Initially I am able to see the button and textbox and grid as well but when i enter the value in textbox and then press the button i need to show that entered values in kendo UI GRID ...

When I run this application in google chrome it was giving empty grid,after enters the value and then press the submit button but when I run this one in IE8 it was giving error like this at starting stage itself....

Unhandled exception at line 238, column 37 in Function code 0x800a138f - Microsoft JScript runtime error: 'data.EmployeeDetails.EmployeeId' is null or not an object

and this is my model

    public class TextBoxGrid
    {
        public string EnteredValue { get; set; }
        public List<EmployeeDetails> employees;
    }  
    public class ParentViewModel
    {
        public EmployeeDetails EmployeeDetails { get; set; }
        public TextBoxGrid TextBoxGrid { get; set; }
    }
    public class EmployeeDetails
    {
        public string EmployeeId { get; set; }
        public string ManagerId { get; set; }
    }

this is my controller

public class EnterValuesGridController : Controller
{
    private static List<EmployeeDetails> empdtls;
    public ActionResult Index( ParentViewModel model)
    {
        var viewmodel = new ParentViewModel
        {
            TextBoxGrid = new TextBoxGrid { employees = GetEmployee().ToList() }
        };
        return View(viewmodel);
    }      
    [HttpPost]
    public ActionResult PostValues(TextBoxGrid model)
    {
        TempData["enteringValue"] = model.EnteredValue;
        var viewmodel = new ParentViewModel
        {
            TextBoxGrid = new TextBoxGrid { employees = GetEmployee().ToList() }
        };
        //ParentViewModel p = new ParentViewModel();
        //TextBoxGrid t = new TextBoxGrid();
        //t.EnteredValue = "a";
        //TempData["a1"] = t.EnteredValue;
        //t.employees = GetEmployee().ToList();
        //p.TextBoxGrid = t;
        //return View("Index", p);   
        return View("Index", viewmodel);        
    }
    public  IEnumerable<EmployeeDetails> GetEmployee()
    {
        string enteredValueId =(string) TempData["enteringValue"];
        string managerId = "M" +enteredValueId;
        empdtls = new List<EmployeeDetails>();
        EmployeeDetails em1 = new EmployeeDetails();
        em1.EmployeeId = enteredValueId;
        em1.ManagerId = managerId;
        empdtls.Add(em1);
        return empdtls.AsEnumerable();
    }
    public ActionResult Orders_Read([DataSourceRequest]DataSourceRequest request)
    {
        return Json(GetOrders().ToDataSourceResult(request));
    }
    private IEnumerable<EmployeeDetails> GetOrders()
    {
        return GetEmployee().AsEnumerable();
    }
}

and this is my view

@model KendoPratapSampleMVCApp.Models.ParentViewModel
@{
    ViewBag.Title = "Index";
}    
@using (Html.BeginForm("PostValues", "EnterValuesGrid", FormMethod.Post))
{ 
     @Html.TextBoxFor(m=>m.TextBoxGrid.EnteredValue)    
     <input type="submit" name="Submitbutton1" value="Submit1" />               
     @(Html.Kendo().Grid<KendoPratapSampleMVCApp.Models.ParentViewModel>()    
    .Name("grid")
    .Columns(columns => {
        columns.Bound(s=>s.EmployeeDetails.EmployeeId).Filterable(false).Width(100);
        columns.Bound(s => s.EmployeeDetails.ManagerId).Filterable(false).Width(100);        
    })
    .Filterable()

        .PageSize(20)
        .Read(read => read.Action("Orders_Read", "EnterValuesGrid"))
     )
  )        
}

I am not sure where I am doing wrong, Would you pls suggest any ideas on this one .. Many thanks...., Do i need to do any changes in UI GRID I have tried changing the post values method ...but it didnot worked for me ...

UPDATE : changed tempData to view Bag...

    [HttpPost]
    public ActionResult PostValues(ParentViewModel model)
    {
        ViewBag.item = model.TextBoxGrid.EnteredValue;

        var viewmodel = new ParentViewModel
        {
            TextBoxGrid = new TextBoxGrid { employees = GetEmployee().ToList() }

        };

        //ParentViewModel p = new ParentViewModel();
        //TextBoxGrid t = new TextBoxGrid();
        //t.EnteredValue = "a";
        //TempData["a1"] = t.EnteredValue;
        //t.employees = GetEmployee().ToList();
        //p.TextBoxGrid = t;
        //return View("Index", p);   
        return View("Index", viewmodel);        
    }

    public  IEnumerable<EmployeeDetails> GetEmployee()
    {
        string enteredValueId = (string)ViewBag.item;
        string managerId = "M" +enteredValueId;
        empdtls = new List<EmployeeDetails>();
        EmployeeDetails em1 = new EmployeeDetails();
        em1.EmployeeId = enteredValueId;
        em1.ManagerId = managerId;
        empdtls.Add(em1);
        return empdtls;
    }

解决方案

Hi pratap i just update your code,

Model

 public class TextBoxGrid
    {
        public string EnteredValue { get; set; }
        public List<EmployeeDetails> employees;
    }
    public class ParentViewModel

        public EmployeeDetails EmployeeDetails { get; set; }
        public TextBoxGrid TextBoxGrid { get; set; }
    }
    public class EmployeeDetails
    {
        public string EnteredValue { get; set; }
        public string EmployeeId { get; set; }
        public string ManagerId { get; set; }
    }
