使用 EditorFor 传递附加视图模型数据在一对多关系中失败
我有一个编辑器模板（Views/Shared/EditorTemplates/HORDER.ascx），它继承了
System.Web.Mvc.ViewUserControl<CCOK2.Models.HORDER>
我的视图模型具有一对多关系，我使用 Html.EditorFor 来渲染多个 HORDERS
<%: Html.EditorFor(model => model.PEOPLE.HORDERS, new {fred="hello"})%>
最终我想要做的是传入下拉列表的数据，但是，目前，我只是想传递一个字符串“hello”
如果我将以下内容嵌入到 HORDER.ascx 中，
<%: ViewData.Count() %>
我会得到“0”输出。任何获取视图数据的尝试都会失败。
但是，如果我将 EditorFor 与单个项目一起使用，它会按预期工作：我将 FirstHorder 添加到我的视图模型中，设置为 model.PEOPLE.HORDERS.First() 然后 <%: Html.EditorFor(model => model.FirstOrder,新的{fred =“你好”})%>按预期通过 hello。
那么...在使用一对多关系调用 EditorFor 时，有什么方法可以让 EditorFor 处理附加数据吗？
编辑： 其他地方建议我在 ForEach 循环中使用 EditorFor 来对抗各个 HORDERS。这是可行的（即附加的视图数据正确传递），但我最终得到由 EditorFor 呈现的每个控件都具有相同的 id 和名称，而不是 PEOPLE.HORDERS[n].field ，这是不可取的。
I have an editor template (Views/Shared/EditorTemplates/HORDER.ascx) which inherits
System.Web.Mvc.ViewUserControl<CCOK2.Models.HORDER>
My viewmodel has a one-to-many relationship which I use Html.EditorFor in order to render multiple HORDERS
<%: Html.EditorFor(model => model.PEOPLE.HORDERS, new {fred="hello"})%>
Eventually what I want to do is pass in the data for a dropdownlist, however, for the moment, I'm just trying to pass in a string "hello"
If I embed the following in HORDER.ascx
<%: ViewData.Count() %>
I get "0" output. An any attempt to get hold of the viewdata fails.
However if I use EditorFor with a single item it works as expected : I added FirstHorder to my viewmodel, set is as model.PEOPLE.HORDERS.First() then <%: Html.EditorFor(model => model.FirstOrder, new {fred="hello"})%> passes hello as expected.
So... is there any way of getting EditorFor to work with additional data when calling it with a one-to-many relationship?
EDIT:
Its been suggested elsewhere that I use EditorFor in a ForEach loop against the individual HORDERS. This works (i.e. the additional viewdata is passed correctly) but I end up with every control rendered by the EditorFor having the same id and name rather than PEOPLE.HORDERS[n].field which is not desirable.

经过一番混乱之后，似乎不可能做到这一点：我认为这是框架中的一个错误。解决方法是在调用 EditorFor 之前将其插入视图数据中。
After much messing it seems that it is not possible to do this: I consider that a bug in the framework. The workaround is to insert it into the viewdata prior to the EditorFor call.
