Question

您好我是MVC的新手，我想在视图中显示webgrid，我正在尝试在同一页面中显示创建和显示，我在webgrid中显示数据时遇到问题，

这是我的代码：控制器：

[HttpPost]
    public ActionResult Insert(Torder Model)
    {
        if(ModelState.IsValid)
        {
            try
            {
                ntity.Torders.Add(Model);
                ntity.SaveChanges();
                ModelState.Clear();
                TempData["notice"] = "Successfully registered";
            }
            catch(Exception ex)
            {
                TempData["Failure"] = ex;
            }
        }
        else
        {
            TempData["Failure"] = "Record Not Saved";
        }

        //var empoyees = Employee.GetList();

        IEnumerable<Torder> model1 = GetProducts();
        return View(model1);
    }
    public IEnumerable<Torder> GetProducts()
    {
        List<Torder> objStudent = new List<Torder>();
        ///*Create instance of entity model*/

        /*Getting data from database for user validation*/
        var _objuserdetail = (from data in ntity.Torders
                              select data);
        foreach (var item in _objuserdetail)
        {
            objStudent.Add(new Torder { Cid = item.Cid, Ccustomername = item.Ccustomername, Citem = item.Citem, Corderamount = (int)item.Corderamount});
        }
        return objStudent;
    }

只需通过您的IEnumerable<Torder> List<Torder>页面就可以写foreach loop并创建网格

--- Example:
public class Torder
{
   public int Id {get;set;}
   public string Name {get;set;}
}

[HttpPost]
    public ActionResult Insert(Torder Model)
    {
        if(ModelState.IsValid)
        {
            try
            {
                ntity.Torders.Add(Model);
                ntity.SaveChanges();
                ModelState.Clear();
                TempData["notice"] = "Successfully registered";
            }
            catch(Exception ex)
            {
                TempData["Failure"] = ex;
            }
        }
        else
        {
            TempData["Failure"] = "Record Not Saved";
        }

        //var empoyees = Employee.GetList();

        List<Torder> model1 = GetProducts();

        return View(model1);
    }
    public List<Torder> GetProducts()
    {
        List<Torder> objStudent = new List<Torder>();
        // your logic
        return objStudent;
    }

---------
Page:
-------------
//html code
@model  List<Torder>
@foreach(Torder order in Model)
{
// here you can build you grid(table) 
order.Name
order.Id
}

P.S将来我建议写＆＃34;清洁＆＃34;没有UI的{{1}}（尝试了解Razor - 它非常好Angular） -

很难从评论中的代码中分辨出来，但您可能只是错过了@grid.GetHtml() 您显示的块定义了网格，但现在您需要发出HTML，以便在页面上显示某些内容。把它放在关闭div标签之前的@ {}块之后。
