Question

我使用模板添加/编辑时遇到了Kendo Grid的问题。添加/编辑的帖子中的对象（ContactEmail）为null，我无法弄清楚原因，ContactID有一个值。我已经看过对KendoUI论坛和类似问题的回答。在这里，但没有发现任何解决我的问题。

即使没有模板它也不起作用，所以它似乎不是我的自定义模板的问题。也没有验证，所以我不明白为什么它不会通过。电子邮件基本上只是电话的副本，只是更改为使用电子邮件对象。

我的视图中有2个Kendo网格，下面是它们的片段。只有电子邮件有问题：

@model DORIS.POCO.Contact
<div id="phones">
  <h4>Phones</h4>
  <div id="phoneGrid" style="width:500px">
    @(Html.Kendo().Grid<DORIS.POCO.ContactPhone>()
        .Name("kendoContactPhones")
        .Columns(columns =>
        {
            columns.Bound(m => m.Number).Title("Phone").ClientTemplate("#= getFormattedPhone(Number) #");
            columns.Bound(m => m.Category).Title("Type");
            columns.Bound(m => m.DescriptionOf).Title("Description");
            columns.Bound(m => m.PrimaryPhone).Title("Primary").ClientTemplate("<input type='checkbox' disabled='true' #= PrimaryPhone ? checked='checked' :'' # />");
        })
        .Sortable()
        .Selectable(s => s
            .Mode(GridSelectionMode.Single)
            .Type(GridSelectionType.Row)
        )
        .DataSource(d => d
            .Ajax()
            .Model(model => model.Id(m => m.PhoneID))
            .Read(read => read.Action("GetContactPhones", "ContactPhones", new{ id = Model.ContactID }))
            .Create(create => create.Action("KendoPhoneAdd", "ContactPhones", new{ id = Model.ContactID }))
            .Update(update => update.Action("KendoPhoneEdit", "ContactPhones"))
            .Destroy(destroy => destroy.Action("KendoPhoneDelete", "ContactPhones"))
            .Sort(s => s.Add(m => m.PrimaryPhone).Descending())
        )
        .AutoBind(true)
        .ToolBar(toolBar => toolBar.Template("<a id='addPhone' class='k-button k-button-icontext k-grid-add'><span class='k-icon k-add'></span>Add</a><a id='editPhone' class='k-button k-button-icontext k-grid-edit'><span class='k-icon k-edit'></span>Edit</a><a id='deletePhone' class='k-button k-button-icontext k-grid-delete'><span class='k-icon k-delete'></span>Delete</a>"))
        .Editable(e => e.Mode(GridEditMode.PopUp).TemplateName("ContactPhone").Window(w => w.Title("Manage Phone")))
        .Events(e => e.DataBound("toggleBacktoTopButton"))
    )
  </div>
</div>
<div id="emails>">
  <h4>Email</h4>
  <div id="emailGrid" style="width:500px">
    @(Html.Kendo().Grid<DORIS.POCO.ContactEmail>()
        .Name("kendoContactEmails")
        .Columns(columns =>
        {
            columns.Bound(m => m.Email).Title("Email");
            columns.Bound(m => m.DescriptionOf).Title("Description");
            columns.Bound(m => m.PrimaryEmail).Title("Primary").ClientTemplate("<input type='checkbox' disabled='true' #= PrimaryEmail ? checked='checked' :'' # />");
        })
        .Sortable()
        .Selectable(s => s
            .Mode(GridSelectionMode.Single)
            .Type(GridSelectionType.Row)
        )
        .DataSource(d => d
            .Ajax()
            .Model(model => model.Id(m => m.EmailID))
            .Read(read => read.Action("GetContactEmails", "ContactEmails", new{ id = Model.ContactID }))
            .Create(create => create.Action("KendoEmailAdd", "ContactEmails", new{ id = Model.ContactID }))
            .Update(update => update.Action("KendoEmailEdit", "ContactEmails"))
            .Destroy(destroy => destroy.Action("KendoEmailDelete", "ContactEmails"))
            .Sort(s => s.Add(m => m.PrimaryEmail).Descending())
        )
        .AutoBind(true)
        .ToolBar(toolBar => toolBar.Template("<a id='addEmail' class='k-button k-button-icontext k-grid-add'><span class='k-icon k-add'></span>Add</a><a id='editEmail' class='k-button k-button-icontext k-grid-edit'><span class='k-icon k-edit'></span>Edit</a><a id='deleteEmail' class='k-button k-button-icontext k-grid-delete'><span class='k-icon k-delete'></span>Delete</a>"))
        .Editable(e => e.Mode(GridEditMode.PopUp).TemplateName("ContactEmail").Window(w => w.Title("Manage Email")))
        .Events(e => e.DataBound("toggleBacktoTopButton"))
    )
  </div>

以下是我的ContactEmailsController的代码，仅限Add Post方法：

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult KendoEmailAdd([DataSourceRequest] DataSourceRequest request, ContactEmail email, int id)
{
  if (email != null)
  {
    ContactEmail newEmail = new ContactEmail();

    newEmail.DescriptionOf = email.DescriptionOf;
    newEmail.Email = email.Email;
    newEmail.EntityID = id;
    newEmail.PrimaryEmail = email.PrimaryEmail;

    db.ContactEmails.Add(newEmail);
    db.SaveChanges();
  }

  return Json(new[] { email }.ToDataSourceResult(request, ModelState));
}

这是我的ContactEmail类：

public partial class ContactEmail
{
    public int EmailID { get; set; }
    public int EntityID { get; set; }
    public string Email { get; set; }
    public string DescriptionOf { get; set; }
    public bool PrimaryEmail { get; set; }

    public virtual Contact Contact { get; set; }
}

最后，这是我的ContactEmail的编辑模板：

@model DORIS.POCO.ContactEmail

@Html.HiddenFor(m => m.EmailID)
@Html.HiddenFor(m => m.EntityID)

<div class="editor-label">
  @Html.LabelFor(m => m.Email)
</div>
<div class="editor-field">
  @Html.EditorFor(m => m.Email )
  @Html.ValidationMessageFor(m => m.Email)
</div>

<div class="editor-label">
  @Html.Label("Description")
</div>
<div class="editor-field">
  @Html.EditorFor(m => m.DescriptionOf)
  @Html.ValidationMessageFor(m => m.DescriptionOf)
</div>

<div class="editor-label">
  @Html.Label("Primary Email")
</div>
<div class="editor-field">
  @Html.CheckBoxFor(m => m.PrimaryEmail)
  @Html.ValidationMessageFor(m => m.PrimaryEmail)
</div>

我已经看了很长一段时间，包括在互联网上寻找解决方案。也许我看起来太难了，答案非常简单。

我相信我已经包含了与此问题相关的所有代码，但如果您认为我错过了某些内容，请告诉我，我会添加它。

谢谢！非常感谢任何帮助！

事实证明，在控制器中命名我的变量是一个问题。我将帖子更改为：

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult KendoEmailAdd([DataSourceRequest] DataSourceRequest request, ContactEmail newEmail, int id)
{
  if (newEmail != null)
  {
    ContactEmail email = new ContactEmail();

    email.DescriptionOf = newEmail.DescriptionOf;
    email.Email = newEmail.Email;
    email.EntityID = id;
    email.PrimaryEmail = newEmail.PrimaryEmail;

    db.ContactEmails.Add(email);
    db.SaveChanges();
  }

  return Json(new[] { newEmail }.ToDataSourceResult(request, ModelState));
}

由于我的ContactEmail对象有一个名为“Email”的属性，因此与我名为“email”的变量冲突。
