Menu
I have a simple form with a list of items in it and I'd like to post them to the controller but funny thing is I just cant. Everything else goes through properly except the list. I checked the ajax call in firebug and the post values are there like this:
Answers[0].IsMissing False
Answers[0].Text Ja
Answers[0].Value 0
Answers[1].IsMissing False
Answers[1].Text Nein
Answers[1].Value 1
Id 1cd14b08-ce3b-4671-8cf8-1bcf69f12b2d
Name Ja/Nein
I have an AnwserScheme class with the following properties:
public string Name { get; set; }
public bool IsMissing { get; set; }
public List<AnswerDisplayItem> Answers { get; set; }
public AnswerScheme()
{
Answers = new List<AnswerDisplayItem>();
}
I have this view code:
@for (int i = 0; i < Model.Answers.Count; i++) {
<tr>
<td>
@Html.HiddenFor(model => Model.Answers[i].IsMissing)
@Html.TextBoxFor(model => Model.Answers[i].Value,
new { @class = "inputValue" })
</td>
<td>
@Html.TextBoxFor(model => Model.Answers[i].Text,
new { @class = "inputAnswer" })
</td>
<td>
<span class="span-delete"
data-answer-scheme-id="@Model.Id"
data-answer-id="@Model.Answers[i].Id" >x</span>
</td>
</tr>
}
I have this piece of ajax code that is responsible for posting:
$.ajax({
url: "/AnswerScheme/AddAnswer",
type: "post",
data: $("#formAnswerScheme").serialize(),
success: function (data) {
console.log(data);
$("#divAnswerSchemeContainer").html(data);
}
});
I have an add answer action in my controller:
[HttpPost]
public PartialViewResult AddAnswer(AnswerScheme answerScheme)
{
...some logic comes here
}
So in the end the controller recieves the model, but only the simple properties, not the list. Any help would be greatly appreciated! cheers.

I wish I could see more of your classes and code, because you don't have something set up right.
I recreated something from what you did provide, which works. I created an MVC 3 project for this sample.
Views/Shared/_Layout.cshtml
<!DOCTYPE html>
<html>
<head>
<title>@ViewBag.Title</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"></script>
</head>

@RenderBody()

@for (int i = 0; i < Model.Answers.Count; i++) {

@Html.HiddenFor(model => Model.Answers[i].IsMissing)
@Html.TextBoxFor(model => Model.Answers[i].Value, new { @class = "inputValue" })
</td>
<td>
@Html.TextBoxFor(model => Model.Answers[i].Text, new { @class = "inputAnswer" })
</td>
<td><span class="span-delete" data-answer-scheme-id="@Model.Id" data-answer-id="@Model.Answers[i].Id" >x</span></td>

}

Its almost identical what TheGeekYouNeed posted, but i guess something is just missing. I have no clue what that could be.
AnswerScheme view:
@using System.Web.Mvc.Html
@using MetaDataPortal.Models
@model AnswerScheme
@{
ViewBag.Title = @Model.IsMissing ? "Missing" : "AnswerScheme";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@section CssContent{
<link href="../../Content/CSS/AnswerScheme.css" rel="stylesheet" />
}
@using (Html.BeginForm("Save", "AnswerScheme", FormMethod.Post, new { id = "formAnswerScheme" })) {
<div id="divAnswerSchemeContainer">
@{Html.RenderPartial("_AnswerScheme", Model);}
</div>
<input type="button" class="clear inputButton" id="buttonAddCode" value="Add @(Model.IsMissing ? "Missing" : "Answer")" />
<input type="submit" value="Save" />
}
@section Javascript{
<script type="text/javascript">
$(function () {
$("#buttonAddCode").click(function () {
$.ajax({
url: "/AnswerScheme/AddAnswer",
type: "post",
async: false,
data: $("#formAnswerScheme").serialize(),
success: function (data) {
console.log(data);
$("#divAnswerSchemeContainer").html(data);
}
});
return false;
});
});
</script>
<script type="text/javascript" src="~/Content/JavaScript/AnswerScheme.js"></script>
}
_AnswerScheme partialview

}

</table>
</li>
</ul>
AnswerScheme.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using Opit.Rogatus.DomainObjects;
namespace MetaDataPortal.Models
{
public class AnswerScheme : BaseModel
{
public string Name { get; set; }
public bool IsMissing { get; set; }
public List<AnswerDisplayItem> Answers { get; set; }
public AnswerScheme()
{
Answers = new List<AnswerDisplayItem>();
}
public AnswerScheme(CodeList codeList, bool isMissing) : this()
{
Id = codeList.Id;
Name = codeList.Name;
IsMissing = isMissing;
foreach (Code code in codeList.Codes.Where(code => code.Category.IsMissing == isMissing))
{
Answers.Add(new AnswerDisplayItem(code));
}
}
}
}
AnswerDisplayItem.cs:
using System;
using Opit.Rogatus.DomainObjects;
namespace MetaDataPortal.Models
{
public class AnswerDisplayItem
{
public Guid Id { get; private set; }
public short Value { get; private set; }
public string Text { get; private set; }
public Guid AnswerSchemeId { get; set; }
public bool IsMissing { get; private set; }
public AnswerDisplayItem()
{
}
public AnswerDisplayItem(Code code)
{
Id = code.Id;
Value = code.Value;
Text = code.Category.Name;
IsMissing = code.Category.IsMissing;
if (code.CodeList == null) return;
AnswerSchemeId = code.CodeList.Id;
}
}
}
And controller is pretty much the same.

You can do like this create model
public class ApplicationInfo
{
public List<ApplicationAccessRoles> ApplAccessRoleInfo { get; set; }
}
public class ApplicationAccessRoles
{
public int app_access_role_key { get; set; }
public int app_key { get; set; }
public string access_role { get; set; }
public bool inactive { get; set; }
}
put it in view
<div class="step-pane" id="step3">
<div class="form-horizontal" style="vertical-align:central;margin-left:150px">
<table id="RolesDetails" cellpadding="0" cellspacing="0" class="data_table">
<tr class="dataheader">
<td class="width5">
@Html.HiddenFor(m => m.app_access_role_key)
</td>
<td class="width200">
Access Roles Name
</td>
<td class="width10">
Inactive
</td>
</tr>
@if (Model.ApplAccessRoleInfo.Count!= 0)
{
var chk = Model.ApplAccessRoleInfo.Count;
for (int a = 0; a < Model.ApplAccessRoleInfo.Count; a++)
{
<tr class="exp_col_header top_border_nil">
@if ((chk - 1) == a)
{
<td><a href="#" class="gridexpand" rel="1"></a></td>
}
else
{
<td></td>
}
<td>
@Html.HiddenFor(m => m.ApplAccessRoleInfo[a].app_access_role_key)
@Html.EditorFor(m => m.ApplAccessRoleInfo[a].access_role)
</td>
<td>
@Html.CheckBox("ApplTeamAccessInfo[" + a.ToString() + "].inactive", false, new { @class = "check-box"})
</td>
</tr>
}
}
else
{
<tr class="exp_col_header top_border_nil">
<td>
<a href="#" class="gridexpand" rel="1"></a>
</td>
<td>
@*@Html.EditorFor(model => model.access_role)*@
@*@Html.EditorFor(m => m.ApplAccessRoleInfo[0].access_role)*@
@Html.EditorFor(model=>model.access_role)
</td>
<td>
@Html.CheckBoxFor(model => model.inactive)
</td>
</tr>
}
</table>
</div>
</div>
In Controller
var main = (from a in db.mas_app_access_roles
where a.app_key == AppInfo.app_key
select new ApplicationAccessRoles
{
app_access_role_key = a.app_access_role_key,
access_role = a.access_role,
inactive = a.inactive,
}).ToList();
access = main;
AppInfo.ApplAccessRoleInfo = access;
ViewBag.check = access;
return View(AppInfo);
