I have an MVC3 page comprised of the following components:
ProfileController - Contains all of the actions and loads all of the views below
/Profile/Index - This action method creates an instance of UserViewModel, which contains several properties and nested collections, including one called "PrefPrograms" which is of type "PreferencePrograms," which is defined as:
public class PreferencePrograms : List<PreferenceProgram>
The "Index" action method populates the PrefPrograms collection and the rest of the UserViewModel and passes that model into the strongly typed "Index.cshtml" view.
Index.cshtml - This is a strongly-typed view of type "UserViewModel." It is comprised of multiple partial views. One partial view within this page, named "Preferences.cshtml," provides a formatted display of the PrefPrograms collection. The relevant portion of Index.cshtml is below.
@model ProfilePreferenceCenterProto.Models.UserViewModel
@{ Html.RenderPartial("Preferences", Model); }
Preferences.cshtml - This strongly-typed partial view is loaded by Index.cshtml using Html.RenderPartial (above). Within Preferences.cshtml, I have a Begin.AjaxForm() method for posting to a "PreferenceSubmit" action and the input submit button is at the bottom of this partial view. Within the partial view, I call an @Html.EditorFor() helper to load an Editor Template for each "PreferenceProgramModel" item in the "PrefPrograms" collection.
Here's my problem - all items load correctly (including the partial view and editorfor components), but when I post the form on Preferences.cshtml to the "PreferencesSubmit" action, the model's values are not passed (the model is instantiated, but the values are only initialized - the property and collection values are not actually passed back to the controller).
The Preferences.cshtml Partial View is shown below.
@model ProfilePreferenceCenterProto.Models.UserViewModel
<div id="accordian">
@using(Ajax.BeginForm("PreferencesSubmit", "Profile", new AjaxOptions{ UpdateTargetId = "accordian" })){
<div id="accordion">
<ul class="tabs">
</ul>
<div class="panes">
<div>
@{
List<string> AffiliateNames = new List<string>();
foreach(ProfilePreferenceCenterProto.Models.PreferenceProgramModel list in Model.PrefPrograms)
{
AffiliateNames.Add(list.SubcategoryName);
}
IEnumerable<string> listNames = AffiliateNames.Distinct();
int counter = 0;
}
@foreach (string AccordionTabName in listNames)
{
<h2>@AccordionTabName</h2>
<div class="pane" @if (counter == 0){ <text>style="display:block;"</text> } >
<table>
<tr class="row">
<th class="name">Subscription</th>
<th class="icon">Email</th>
<th class="icon">SMS</th>
<th class="icon">Facebook</th>
<th class="icon">Mail</th>
<th class="icon">Phone</th>
</tr>
@{
counter++;
var TabPrograms = (from l in Model.PrefPrograms
where l.SubcategoryName == @AccordionTabName
select l);
}
@Html.EditorFor(m => TabPrograms)
</table>
</div>
}
</div>
</div>
</div>
<div align="center"><input type="submit" value="Save Preferences" /></div>
}
/Shared/EditorTemplates/PreferenceProgramModel.cshtml - The Editor Template for "PreferenceProgramModel" items, defined as follows:
@model ProfilePreferenceCenterProto.Models.PreferenceProgramModel
<tr class="row">
<td class="name">@Model.ListName</td>
<td class="icon">
@if (Model.EmailEnabled)
{
<a id="@Model.EmailFilterID" href="#" onclick="ImageClick(@Html.IdFor(m => m.EmailStatus));"><img height="25" width="28" src="@Model.Email_Icon_NotSelected" /></a>
}

<td class="icon">
@if (Model.SMSEnabled)

<td class="icon">
@if (Model.FBEnabled)

<a id="@Model.FBFilterID" href="#"><img height="25" width="28" src="@Model.FB_Icon_NotSelected" /></a>
}

<a id="@Model.MailFilterID" href="#"><img height="25" width="28" src="@Model.Mail_Icon_NotSelected" /></a>
}

<td class="icon">
@if (Model.PhoneEnabled)
{
<a id="@Model.PhoneFilterID" href="#"><img height="25" width="28" src="@Model.Phone_Icon_NotSelected" /></a>
}

@Html.HiddenFor(m => m.EmailStatus)
@Html.HiddenFor(m => m.SMSStatus)
@Html.HiddenFor(m => m.FBStatus)
@Html.HiddenFor(m => m.MailStatus)
@Html.HiddenFor(m => m.PhoneStatus)
<script type="text/javascript">
$(document).ready(function () {
function ImageClick(Resource) {
alert(Resource.attr("value"));
if (Resource.attr("value") != 1) {
Resource.val("1");
}
else {
Resource.val("2");
}
alert(Resource.attr("value"));
}
if ("@Model.EmailEnabled" == "True") {
$("#@Model.EmailFilterID").click(function () {
ImageClick($("#@Html.IdFor(m => m.EmailStatus)"));
return false;
});
}
if ("@Model.SMSEnabled" == "True") {
$("#@Model.SMSFilterID").click(function () {
ImageClick($("#@Html.IdFor(m => m.SMSStatus)"));
return false;
});
}
if ("@Model.FBEnabled" == "True") {
$("#@Model.FBFilterID").click(function () {
ImageClick($("#@Html.IdFor(m => m.FBStatus)"));
return false;
});
}
if ("@Model.MailEnabled" == "True") {
$("#@Model.MailFilterID").click(function () {
ImageClick($("#@Html.IdFor(m => m.MailStatus)"));
return false;
});
}
if ("@Model.PhoneEnabled" == "True") {
$("#@Model.PhoneFilterID").click(function () {
ImageClick($("#@Html.IdFor(m => m.PhoneStatus)"));
return false;
});
}
});
</script>
The PreferencesSubmit controller action is defined with this signature:
public ActionResult PreferencesSubmit(Models.UserViewModel model)
The rendered form tag from the the page is below:
<form action="/Profile/PreferencesSubmit" data-ajax="true" data-ajax-mode="replace" data-ajax-update="#accordian" id="form0" method="post">
Some of the rendered hidden fields are shown below:
<input data-val="true" data-val-number="The field EmailStatus must be a number." data-val-required="The EmailStatus field is required." id="TabPrograms_0__EmailStatus" name="TabPrograms[0].EmailStatus" type="hidden" value="0" />
<input data-val="true" data-val-number="The field SMSStatus must be a number." data-val-required="The SMSStatus field is required." id="TabPrograms_0__SMSStatus" name="TabPrograms[0].SMSStatus" type="hidden" value="0" />
<input data-val="true" data-val-number="The field FBStatus must be a number." data-val-required="The FBStatus field is required." id="TabPrograms_0__FBStatus" name="TabPrograms[0].FBStatus" type="hidden" value="0" />
<input data-val="true" data-val-number="The field MailStatus must be a number." data-val-required="The MailStatus field is required." id="TabPrograms_0__MailStatus" name="TabPrograms[0].MailStatus" type="hidden" value="0" />
<input data-val="true" data-val-number="The field PhoneStatus must be a number." data-val-required="The PhoneStatus field is required." id="TabPrograms_0__PhoneStatus" name="TabPrograms[0].PhoneStatus" type="hidden" value="0" />
I've verified that ModelState.IsValid is true when PreferencesSubmit is called, but the model itself does not contain the actual values from the page. How do I pass my strongly-typed model values from the partial view back to the Action method on submit?
