HI我被困在获取数据，我需要显示在剑道UI GRID，起初我能够看到按钮和文本框和电网以及但是当我在文本框中输入值，然后按下按钮，我需要证明进入在剑道UI网格值...
当我运行谷歌浏览器这个应用程序这是给空格，之后进入值，然后按提交按钮，但是当我在IE8上运行这个它是在起步阶段给予自己这样的错误....
Unhandled exception at line 238, column 37 in Function code 0x800a138f - Microsoft JScript runtime error: 'data.EmployeeDetails.EmployeeId' is null or not an object
这是我的模型
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; }
}
这是我的控制器
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();
}
}
这是我的看法
@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()
.HtmlAttributes(new { style = "height:430px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Read(read => read.Action("Orders_Read", "EnterValuesGrid"))
)
)
}
我不知道我在哪里做错了，你会请建议在这一个..非常感谢任何想法....，做我需要做的UI GRID我试图改变后的数值方法的任何改变......但它因此未工作对我来说...
UPDATE：改变的TempData查看背包
[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;
}
