C＃MVC Kendo Grid不显示数据，但似乎知道它

Question

所以我试图实现一个Kendo MVC网格到大学任务，我的问题是网格说“无数据”，但当我点击一个该列的名称显示了一些包含应该在网格中的数据的文本。图片：

My Grid in my browser window

What gets displayed when I click one of the column names

我的代码：

为网格控制器：

public class KurseSuchenGridController : Controller 
{ 
private ApplicationDbContext db = new ApplicationDbContext(); 

public ActionResult KurseSuchenGrid() 
{ 
    return View(); 
} 

public ActionResult Kurse_Read([DataSourceRequest]DataSourceRequest request) 
{ 
    IQueryable<Kurs> kurse = db.Kurse; 
    DataSourceResult result = kurse.ToDataSourceResult(request, kurs => new { 
     Id = kurs.Id, 
     Titel = kurs.Titel, 
     Inhaltsbeschreibung = kurs.Inhaltsbeschreibung, 
     Agenda = kurs.Agenda, 
     Ortsangabe = kurs.Ortsangabe, 
     Termin = kurs.Termin, 
     Anmeldeschluss = kurs.Anmeldeschluss, 
     //gelistet = kurs.gelistet, 
     ApplicationUserId = kurs.ApplicationUserId 
    }); 

    return Json(result, JsonRequestBehavior.AllowGet); 
} 


protected override void Dispose(bool disposing) 
{ 
    db.Dispose(); 
    base.Dispose(disposing); 
} 

笔者认为：

@(Html.Kendo().Grid<Plattform.Models.Kurs>() 
     .Name("grid") 
     .Columns(columns => 
     { 
     columns.Bound(c => c.Titel); 
     columns.Bound(c => c.Inhaltsbeschreibung); 
     columns.Bound(c => c.Agenda); 
     columns.Bound(c => c.Ortsangabe); 
     columns.Bound(c => c.Termin); 
     columns.Bound(c => c.Anmeldeschluss); 

     columns.Bound(c => c.ApplicationUserId); 
     }) 
     .Pageable() 
     .Sortable(sortable => { 
      sortable.SortMode(GridSortMode.SingleColumn); 
     }) 
     .Filterable(filterable => filterable.Mode(GridFilterMode.Row)) 
     .Scrollable() 
     .DataSource(dataSource => dataSource 
      .Ajax() 
      .Read(read => read.Action("Kurse_Read", "KurseSuchenGrid")) 
      .PageSize(20) 
    ) 
) 

Answer 1

添加这样的模型：

.Model(model => 
    { 
     model.Id(b => b.field1); 
     model.Field(b => b.field2); 
     model.Field(b => b.field3); 
     model.Field(b => b.field4); 
     model.Field(b => b.field5); 
     ... 
    }) 

Answer 2

看来你在做服务器操作。如果是这样，您可能需要添加ServerOperation(true)，并添加Model(model => model.Id(m => m.Id))，并将[HttpPost]添加到操作方法。

.DataSource(dataSource => dataSource 
    .Ajax() 
    .ServerOperation(true) <===== 
    .Model(model => model.Id(m => m.Id)) <===== 
    .Read(read => read.Action("Kurse_Read", "KurseSuchenGrid")) 
    .PageSize(20) 
    ) 

[HttpPost] <===== 
public ActionResult Kurse_Read([DataSourceRequest]DataSourceRequest request) 
{ 
    ... 
}
