问候每个人,
我在使用部分视图时遇到了一些问题,我正在使用它作为编辑表单。除了表单中隐藏的元素,模型在传递给我的EditContact帖子控制器时为null。
我应该补充一点,我意识到有一种更无缝的方式来做我正在使用AJAX做的事情,但我想如果我能先解决笨重的方式,它会帮助我更好地理解这项工作。 这是我的EditContact局部视图:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<WebUI.DataAccess.CONTACT>" %>
<div id="contactPartial-<%= ViewData.Model.id %>">
<% Html.EnableClientValidation(); %>
<% using (Html.BeginForm("EditContact", "Investigator"))
{ %>
<%= Html.HiddenFor(Model => Model.id) %>
<%= Html.HiddenFor(Model => Model.investId) %>
<table id="EditContact-<%= ViewData.Model.id %>" width="100%">
<tr>
<th colspan="4">
<b>New Contact</b>
</th>
</tr>
<tr>
<td>
<b>
<%= Html.LabelFor(Model => Model.type)%></b><br />
<%= Html.EditorFor(Model => Model.type, null, "contactType-" + ViewData.Model.id)%><br />
<%= Html.ValidationMessageFor(Model => Model.type) %>
</td>
</tr>
<tr>
<td>
<b>
<%= Html.LabelFor(Model => Model.salutation)%></b><br />
<%= Html.EditorFor(Model => Model.salutation, null, "contactsalutation-"+ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.firstName)%></b><br />
<%= Html.EditorFor(Model => Model.firstName, null, "contactFirstName-"+ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.middleName)%></b><br />
<%= Html.EditorFor(Model => Model.middleName, null, "contactMiddleName-"+ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.lastName)%></b><br />
<%= Html.EditorFor(Model => Model.lastName, null, "contactLastName-"+ViewData.Model.id)%><br />
<%= Html.ValidationMessageFor(Model => Model.lastName)%>
</td>
</tr>
<tr>
<td>
<b>
<%= Html.LabelFor(Model => Model.title)%></b><br />
<%= Html.EditorFor(Model => Model.title, null, "contactTitle-"+ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.phone)%></b><br />
<%= Html.EditorFor(Model => Model.phone, null, "contactPhone="+ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.altPhone)%></b><br />
<%= Html.EditorFor(Model => Model.altPhone, null, "contactAltPhone-" + ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.fax)%></b><br />
<%= Html.EditorFor(Model => Model.fax, null, "contactFax-" + ViewData.Model.id)%>
</td>
</tr>
<tr>
<td>
<b>
<%= Html.LabelFor(Model => Model.email)%></b><br />
<%= Html.EditorFor(Model => Model.email, null, "contactEmail-" + ViewData.Model.id)%>
</td>
<td>
<b>
<%= Html.LabelFor(Model => Model.comment)%></b><br />
<%= Html.EditorFor(Model => Model.comment, null, "contactComment-" + ViewData.Model.id)%>
</td>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
<input type="submit" value="Save" />
</td>
<td>
<button id="<%= ViewData.Model.id %>" class="contactEditHide">
Cancel</button>
</td>
<td>
</td>
<td>
</td>
</tr>
</table>
<% } %>
</div>
当传递编辑联系人帖子控制器时,仅模型id和investId具有值;其他一切都是空的。这是我在详细信息视图中渲染局部视图的方式:
<table width="100%">
<tr>
<th colspan="7">
<b>Contacts</b>
</th>
<th id="contactButton" class="button">
<button id="showEditContact-0" type="button" class="contactEditShow">New Contact</button>
</th>
</tr>
<tr>
<th>
Type
</th>
<th>
Name
</th>
<th colspan="2">
Title
</th>
<th>
Prim. & Alt. Phone
</th>
<th>
Fax
</th>
<th colspan="2">
Comment
</th>
</tr>
<% for (int i = 0; i < Model.CONTACTs.Count; i++)
{ %>
<tr id="contactRow-<%= Model.CONTACTs[i].id %>" class="contactRow">
<td>
<%= Html.Encode(Model.CONTACTs[i].type)%>
</td>
<td>
<%= Html.Encode(Model.CONTACTs[i].salutation)%>
<%= Html.Encode(Model.CONTACTs[i].firstName)%>
<%= Html.Encode(Model.CONTACTs[i].middleName)%>
<%= Html.Encode(Model.CONTACTs[i].lastName)%>
<br />
<a href="mailto:<%= Html.AttributeEncode(Model.CONTACTs[i].email) %>">
<%= Html.Encode(Model.CONTACTs[i].email)%></a>
</td>
<td colspan="2">
<%= Html.Encode(Model.CONTACTs[i].title)%>
</td>
<td>
Prim:<%= Html.Encode(Model.CONTACTs[i].phone)%><br />
Alt:<%= Html.Encode(Model.CONTACTs[i].altPhone)%>
</td>
<td>
<%= Html.Encode(Model.CONTACTs[i].fax)%>
</td>
<td>
<%= Html.Encode(Model.CONTACTs[i].comment)%>
</td>
<td>
<button id="<%= Model.CONTACTs[i].id %>" type="button" class="contactEditShow">Edit Contact</button>
</td>
</tr>
<tr>
<td colspan="8">
<% Html.RenderPartial("EditContact", Model.CONTACTs[i]); %>
</td>
</tr>
<% } %>
</table>
我的详细信息视图强烈关注INVESTIGATOR模型:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<WebUI.DataAccess.INVESTIGATOR>" %>
如上所示,我的部分视图是对CONTACTS模型的强类型。
我在模型绑定中遇到了类似的问题,在一个视图中,我试图允许一次编辑地址的所有层并通过索引模型来修复它,类似于上面的Details视图。看来我需要在部分视图中做同样的事情以确保模型绑定,但我不确定如何实现这一点(有语法问题)。
当然,我可能会在这里需要一个新的解决方案! 如果您需要更多细节,请告诉我们!谢谢!

你为什么使用
<%= Html.EditorFor(Model => Model.salutation, null, "contactsalutation-"+ViewData.Model.id)%>
如果您使用它就像这样
<%= Html.EditorFor(Model => Model.salutation) %>
应该有效。
为了映射您的模型,您的控件需要具有与其名称相同的ID,并且您正在使用的第三个参数会更改您的控件ID。

使用Html.EditorFor代替Html.RenderPartial。
