我正在通过ajax调用来调用控制器，以将数据绑定到kendo网格。当我与[DataSourceRequest] DataSourceRequest请求一起发送附加参数时，网格不会绑定数据。第二个参数是将值正确获取到控制器，并从数据库中获取正确的json数据。但是只有绑定才是问题。
我尝试将JsonRequestBehavior.AllowGet添加到我的Json返回中。
home.cshtml
在此文件中，对于“呼叫记录”字段，我正在发送2个参数。即([DataSourceRequest]DataSourceRequest请求和CallRecording，如下面的代码所示。

HomeController.cs
这是后端控制器方法，它接受2个参数。当从视图发送到callrecording参数的值时，如果使用相同的参数值，则网格未绑定数据。如果我直接对callRecording的值进行硬编码，那么网格将绑定数据。在这两种情况下，都将返回预期的json值。
[HttpGet]
public ActionResult Agent([DataSourceRequest]DataSourceRequest request, string CallRecording)
{
using (var data = new SampleData())
{
IQueryable<SentimentAnalytics> semanticAnalyticsofUsers = data.SentimentAnalytics.Where(a => a.CallRecording.Equals(CallRecording));
DataSourceResult result = semanticAnalyticsofUsers.ToDataSourceResult(request);
return Json(result, JsonRequestBehavior.AllowGet);
}
}
局部视图（Agent.cshtml）
@using Kendo.Mvc.UI;
@(Html.Kendo().Grid<MiCustomerSentiment.SentimentAnalytics>()
.Name("agent")
.DataSource(dataSource => dataSource // Configure the grid data source
.Ajax() // Specify that ajax binding is used
.Read(read => read.Action("Agent", "Home", new { CallRecording = "#= CallRecording #" }))
)
.Columns(columns =>
{
columns.Bound(user => user.AgentName).Title("Agent Name");
columns.Bound(user => user.CustomerType).Title("Customer Type");
columns.Bound(user => user.CaseNumber).Title("Case Number").ClientTemplate(Ajax.ActionLink("#= CaseNumber #", "CaseDetails", "Home", new { callRecordingId = "#= CallRecording #" }, new AjaxOptions() { OnSuccess = "myJSFunctionForCaseDetails" }).ToHtmlString());
columns.Bound(user => user.InteractionTime).Title("Talk Time");
columns.Bound(user => user.IdleTime).Title("Idle Time");
//columns.Bound(user => user.Emotion).Title("Emotion").ClientTemplate("#= Emotion # <img src='../../Images/positive_smiley.jpg' style='width:40px;'/>");
//columns.Bound(user => user.Emotion).Title("Emotion").ClientTemplate("#= Emotion # #=GetImage(user.Emotion)# ");
columns.Bound(user => user.Emotion).Title("Emotion").ClientTemplate("#= Emotion # #=GetImage(data.Emotion)#");
})
.HtmlAttributes(new { style = "height: 130px;" })
.Scrollable(a => a.Height("auto"))

.Pageable(pageable => pageable

.ButtonCount(5)))
请告诉我，为什么使用参数的实际值时网格未绑定数据？
在控制器中使用传递给控制器的其他参数时，Kendo网格应绑定数据。
