我有一个多选内部子网格，我想设置基于父级的编辑的数据源。我无法获得多选的参考 这里是我的代码，gridDetailInit amenities变量的长度为0，这意味着无法找到它。Kendo UI ASP.NET MVC Hierarcy Grid - DetailInit

编辑： 的territoriesTemplate装载来自EditorTemplate（AmenitiesEditor.chtml）一partialView
@model IEnumerable<BladeRez.Creator2.Models.AmenityItem>
@（Html.Kendo（）。MultiSelectFor（M => M）
.Placeholder("Select/add amenities...")
.DataTextField("text")
.DataValueField("value")
.Filter(FilterType.Contains)
.Animation(false)
.BindTo((IEnumerable<BladeRez.Creator2.Models.AmenityItem>)ViewData["AmenityList"])
)
这是访问，因为我有UIHint我RoomModel财产对于AmenityList作为这样
[UIHint("AmenitiesEditor")]
public IEnumerable<AmenityItem> AmenityList
{
get;
set;
}

你是正确的，我是问的东西，是不存在的，所以这里是我到目前为止 VAR parentAmenities = e.sender.dataItem（e.masterRow）.AmenityList; var detailGrid = e.detailRow.find（“.k-grid”）。data（“kendoGrid”）; 但是现在我需要找到细节网格中的所有多重选择（数据源尚未设置，因为detailInit在LoadRooms之前触发，所以我使用什么或者如何获取所有多选的列表还没有存在） – Zoinky
你多次提到细节网格中的多重选择，那么多重选择是什么？我没有看到任何地方声明了任何MultiSelect小部件，可能你的意思是别的吗？ –
编辑了原始文章，multiselect是telerik提供的另一个小工具，我的道歉，我认为任何人回答这个问题都会知道我指的是telerik的kendo ui控件。 – Zoinky
