BeginCollectionItem 未绑定
BeginCollectionItem not binding
我以前使用过 Html.BeginCollectionItem() 扩展，从视图到控制器的绑定没有问题。然而，在我当前的项目中我遇到了问题。
模特
public class EditPathViewModel : TradeContractorEscalationPath
{
public Guid ContractorId { get; set; }
public List<ContactDisplayModel> Contacts { get; set; }
public List<TradeContractorEscalationPathContact> AssignedContacts { get; set; }
public int maxOrder { get; set; }
}
public partial class TradeContractorEscalationPath
{
public System.Guid Id { get; set; }
public System.Guid TradeContractorId { get; set; }
public string Description { get; set; }
public string Notes { get; set; }
public System.DateTime CreatedDate { get; set; }
public Nullable<System.DateTime> UpdatedDate { get; set; }
}
我正在尝试将 AssignedContacts 绑定回 Controller，它看起来像...
[HttpPost]
public async Task<ActionResult> EditPath([Bind(Include = "Id,TradeContractorId,Description,Notes,ContractorId,AssignedContacts,Contacts")] Models.EditPathViewModel model)
{
...
}
然而，它不断地returns null。 BeginCollectionItem 的配置如下：
TradeContractorEscalationPathContact 的编辑器模板
@model Telecare.POCO.TradeContractorEscalationPathContact
@Html.EditorFor(model => model.Order)
@Html.EditorFor(model => model.TradeContractorEscalationPathId)
@Html.EditorFor(model => model.ContactId)
调用 Assigned Contacts 集合项的视图
...
<div class="col-lg-6">
<div class="ibox-title">
<h5>Contacts</h5>
</div>
<div class="ibox-content">
@Html.EditorFor(model => model.AssignedContacts)
</div>
</div>
...

从我读过的所有线程来看 - HTML 看起来应该正确绑定，所以我一定是遗漏了什么或在其他地方做错了什么？有人有什么想法吗？
提前致谢
好的 - 原来我是个白痴。上面的代码确实有效，但它不具有约束力，因为它不在 @Html.BeginForm()) 部分中。叹息
