劍道ASP.NET MVC - 指數超出範圍的數據綁定

Question

試圖綁定一個DataTable的Telerik的劍道網格時，我發現了以下錯誤：

指數超出範圍。必須是非負數且小於集合的大小。

我已經按照Telerik的示例項目，但在我的代碼，它似乎是在「數據源」的「讀取」功能失效：

.Read（讀=> read.Action（「讀「），」Events「））

我有ActionResult Read（）當前返回null，僅僅是因爲我想看看它是否甚至會使它成爲該函數。另外，我已經介紹過了，數據表返回正確的列和列名稱。

任何幫助表示讚賞。

Events.cshtml

@model System.Data.DataTable 

@{ 
    ViewBag.Title = "Events"; 
    Layout = "~/Views/_mainLayout.cshtml"; 
} 

<p>Events</p> 

@(Html.Kendo().Grid(Model) 
    .Name("GridStatic") 
    .Columns(columns => 
    { 
     columns.Bound("ID"); 
     columns.Bound("EntryType"); 
     columns.Bound("EventDate"); 
     columns.Bound("EventData"); 
     columns.Bound("Source"); 
    }) 
    .Pageable() 
    .Sortable() 
    .Scrollable() 
    .Filterable() 
    .DataSource(dataSource => dataSource 
     .Ajax()  
     .Model(model => 
      { 
       model.Field("ID", typeof(int)); 
       model.Field("EntryType", typeof(DateTime)); 
       model.Field("EventDate", typeof(string)); 
       model.Field("EventData", typeof(string)); 
       model.Field("Source", typeof(string)); 
      }) 
     .Read(read => read.Action("Read", "Events")) 
    ) 
) 

EventsController.cs

public class EventsController : Controller 
{ 
    // 
    // GET: /Events/ 

    public ActionResult Events(string sName) 
    { 
     EventReader ereader = new EventReader(sName); 
     return View(ereader.ParseIntoTable(ereader.GetListOfEvents())); 
    } 

    public ActionResult Read([DataSourceRequest] DataSourceRequest request) 
    { 
     return null; 
    } 
}

這裏是堆棧跟蹤，我不知道如果這將有所幫助。

Answer 1

原來它與我的web.config有關。我遇到了我創建的每個Kendo對象的錯誤。將以下代碼添加到頂層web.config似乎修復了一切。

<runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
    <dependentAssembly> 
     <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> 
     <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0" /> 
    </dependentAssembly> 
    </assemblyBinding> 
</runtime> 

Answer 2

我推測錯誤發生，因爲Read動作沒有返回一個有效的結果集。

通常Kendo網格要求在使用Ajax模式讀取時返回JsonResult。如果你返回一個空的DataTable格式正確的json結果，那麼我懷疑它會修復它。

public ActionResult Read([DataSourceRequest] DataSourceRequest request) 
    { 
    return this.Json(new DataTable().ToDataSourceResult(request)); 
    } 

顯然，你應該替代DataTable爲您的真實結果集。

通過包含在解決方案中的web.config文件部分將幫助你。
