C# 具有ASP.NET MVC的MVVM，部分类作为ViewModel未按预期执行

我使用的是实体框架，因此我不想在EF模型中使用Razor验证语法。出于这个原因，我创建了一个viewmodel来为我进行验证，但很明显，我需要一个在不同状态下支持对象的视图模型。在工作正常的地方，它现在只验证部分字段

两个部分类如下所示

@model EH.BCRT.AdvisoryRequests.Model.BCRTAdvisoryRequest

<link href="@Url.Content("/Content/Site.css")" rel="stylesheet" />
<link href="@Url.Content("/Content/themes/base/jquery.ui.dialog.css")" rel="stylesheet" />
<link href="@Url.Content("/Content/themes/base/jquery.ui.datepicker.css")" rel="stylesheet" />

<form id="advisoryRequestForm">

        @Html.ValidationSummary(true)

至于行为，我希望这对于使用BCRTAdvisoryRequest类作为模型的局部视图来说是足够的信息，可以正确地进行验证，但显然不是

情况就是这样：

该对话框的问题是，一半的必填字段未经验证，所有标签均无效

局部视图编码如下：
