Question

我使用共享编辑器模板在我的视图中使用'EditorFor'HTML帮助器呈现嵌套集合，类似于以下内容。我不喜欢所有这些嵌套的部分视图，但这样做可以恰当地命名元素，以便它们在ViewModel中回发到我的控制器而没有问题。

我如何在最坚决的巢穴中对顺序进行排序？在这种情况下，我如何让“Budget.vbhtml”以年份顺序（降序）显示？

提前致谢！

顶级视图（Organization.vbhtml）：

<div id="budgets">
     @Html.EditorFor(Function(org) org.OrganizationBudgets))
</div>

OrganizationBudget.vbhtml：

@ModelType CharityMVC.OrganizationBudget
@Html.EditorFor(Function(ob) ob.Budget)

Budget.vbhtml：

@ModelType CharityMVC.Budget
@Model.Year @Html.EditorFor(Function(b) b.Amount)

当我填充我的Model对象时，听起来我应该在我的控制器中执行此操作，但是如何在linq查询中对子项或子项进行排序？这是我目前的代码：

Function Edit(ByVal id As Integer) As ActionResult
    Dim o As Organization
    Dim ovm As OrganizationViewModel

    'Load the organization from the database
    o = (From org In _db.Organizations _
        Where org.Id = id _
        Select org).FirstOrDefault()

    'Map it to the ViewModel
    ovm = AutoMapper.Mapper.Map(Of Organization, OrganizationViewModel)(o)

    Return View(ovm)

End Function

到目前为止我的最佳答案：多个LINQ查询填充子属性，如下所示：

Function Edit(ByVal id As Integer) As ActionResult
    Dim o As Organization
    Dim ovm As OrganizationViewModel

    'Load the organization from the database
    o = (From org In _db.Organizations _
        Where org.Id = id _
        Select org).FirstOrDefault()

    o.OrganizationBudgets = (From ob In _db.OrganizationBudgets _
                             Where ob.OrganizationId = o.Id _
                             Order By ob.Budget.Year Descending _
                             Select ob).ToList()


    'Map it to the ViewModel
    ovm = AutoMapper.Mapper.Map(Of Organization, OrganizationViewModel)(o)

    Return View(ovm)

End Function

使用EditorFor对嵌套集合进行排序
