render partial view through ajax

I have a dashboard view. In this dashboard I want to render number of partial views. I started this exercise just for learning purpose. Actually I am not sure what I am doing wrong. Here is my code:
My DashboardController:
public ActionResult DashboardIndex()
{
return View();
}
public ActionResult DebitAndCreditExpensesPV()
{
DashboardModel objGet = new DashboardModel();
DashboardViewModel objVM = new DashboardViewModel();
DateTime date = new DateTime();
objVM.StartDate = new DateTime(date.Year, date.Month, 1);
objVM.EndDate = objVM.StartDate.AddMonths(1).AddDays(-1);
objVM.ExpenseType = objGet.GetExpensesByDebitAndCredit(objVM.StartDate, objVM.EndDate);
return PartialView(objVM);
}
My DashboardIndex.cshtml
#model GPI.ViewModel.DashboardViewModel
#{
ViewBag.Title = "DashboardIndex";
}
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="col-md-4">
#{
Html.RenderPartial("DebitAndCreditExpensesPV");
}
</div>
<div class="col-md-8"></div>
</div>
</div>
</div>
<script>
$(document).ready(function () {
$.ajax({
type: "get",
url: "/Dashboard/DebitAndCreditExpensesPV",
data: {
'startDate': $('#StartDate').val(),
'endDate': $('#EndDate').val()
},
dataType: 'json',
success: function () {
alert('success');
},
error: function () {
alert('failure');
}
});
});
</script>
DashboardModel.cs
public class DashboardViewModel
{
public double ExpenseAmount { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public ExpenseList ExpenseType { get; set; }
}
public class ExpenseList
{
public double TotalDebits { get; set; }
public double TotalCredits { get; set; }
}
My Partial View: DebitAndCreditExpensesPV.cshtml
#model GPI.ViewModel.DashboardViewModel

</div>

I put two break points in my controller: one at 'DashboardIndex' action and other at 'DebitAndCreditExpensesPV'. The first one executes but later one does not. After first breakpoint, I got 'object null reference ' exception in my partial view at this line <strong>#Model.ExpenseType.TotalDebits</strong>.
I want to know why second breakpoint is not executing. I this break point executes, I can not get this exception. Please tell me where I am going wrong.

In the RenderPartial method, you are calling the DebitAndCreditExpensesPv partial view. This view is strongly typed to your DashboardViewModel and you are using different properties of this Model inside the view (Ex :Model.ExpenseType.TotalDebits).
But in your Index view, you are not passing any model object to your RenderPartial method. If you do not pass any object in this method, It will try to use the Model of the parent view(Index). In your case, You Index view does not have any model, So the essentially the Model which the partial view now has is NULL. You are trying to access the ExpenseType property of NULL and that is the reason you are getting the exception.
Even if you fix your index view to pass the model, You are doing it twice. Once via RenderPartial and again you are making a call to the DebitAndCreditExpensesPV method via ajax on the document ready event. May be you can get rid of the RenderPartial call.
So in your index view, Add a div to show the result of the ajax call.
<div id="divDebitAndCredit"></div>
And your script to load the markup to this div. I removed the datatype:"json" as we do not want receive the data in json format.
$(function () {
$.ajax({
type: "get",
url: "#Url.Action("DebitAndCreditExpensesPV","Home")",
data: {
'startDate': $('#StartDate').val(),
'endDate': $('#EndDate').val()
},
success: function (r) {
$("#divDebitAndCredit").html(r);
},
error: function (a,b,c) {
alert('Error ! See browser console');
console.log(b,c);
}
});
});
Now in the above code, you are trying to send the startDate and endDate to the action method. So update your action method to accept those.
public ActionResult DebitAndCreditExpensesPV(DateTime? startDate,DateTime? endDate)
{
DashboardViewModel objVM = new DashboardViewModel();
DateTime date = DateTime.Now;
if(startDate!=null)
{
objVM.StartDate = startDate.Value;
}
else
{
objVM.StartDate = new DateTime(date.Year, date.Month, 1);
}
if(endDate!=null)
{
objVM.EndDate = endDate.Value;
}
else
{
objVM.EndDate = objVM.StartDate.AddMonths(1).AddDays(-1);
}
objVM.ExpenseType = new ExpenseList { TotalCredits = 45.00, TotalDebits = 634.00 };
return PartialView(objVM);
}
But the startDate and endDate input fields are part of the partial view. so when you make the ajax call in the ready event of the index view, those fields won't be part of your page. You can either keep the Partial view inside our div and pass a DashboardViewModel object to the Partial view
#model DashboardViewModel
<div id="divDebitAndCredit">
#{ Html.RenderPartial("DebitAndCreditExpensesPV",Model) }
</div>
This means your Index action should send an object of DashboardViewModel to the index view with whatever default values you want to render.
public ActionResult Index()
{
var objVM = new DashboardViewModel();
DateTime date = DateTime.Now;
objVM.StartDate = new DateTime(date.Year, date.Month, 1);
objVM.EndDate = objVM.StartDate.AddMonths(1).AddDays(-1);
objVM.ExpenseType = new ExpenseList { TotalCredits = 45.00, TotalDebits = 634.00 };
return View(objVM);
}

</div>
UPDATE
if I use HiddenFor on QuizName, it does come back over on post but the rest of the model is empty.

When iterating over a collection that you want to post back to your model, you can't use foreach; you must use a regular for statement with indexing in order for Razor to generate the correct field names.
#for (var i = 0; i < Model.Questions.Count(); i++)
{
...
#Html.RadioButtonFor(m => m.Questions[i].UserAnswer)
}
Then, your fields will have name attributes in the form of Questions[0].UserAnswer, which the modelbinder will recognize and bind appropriately to your model. As you have it now, with the foreach, the field name is being generated as question.UserAnswer, which the modelbinder has no idea what to do with and discards.
Also, FWIW, accessing your context from within your model entity is a hugely bad idea, and even worse if you're not injecting it. Move that logic out of your entity and utilize a utility class or service instead. Also, look into dependency injection, as your context is one of those things that you want one and only one instance of per request. If you start instantiating multiple instances of the same context, you will have problems.

The problem is model binding is going to attempt to bind your form values to properties on your model. It will not use the constructor on your model that takes the quiz name, it will use the default constructor to instantiate the QuizModel object.
I would consider refactoring this model to remove your EntityFramework dependency and find a new way to populate those values.
You should also call the Dispose() method on IDisposable objects when you're done using them.
My suggestion for how to solve this problem would be to use the QuizModel you currently have to help render your view (i.e. Your quiz questions and possible answer for each question).
Create a seperate ViewModel for quiz submission
public class QuizSubmission
{
public string QuizName { get;set; }
public List<QuizQuestionResponse> Responses { get;set; }
}
public class QuizQuestionResponse
{
public int QuestionId { get;set; }
public int AnswerId { get;set; }
}
In your controller action, you should be binding to a QuizSubmission model.
[HttpPost]
public ActionResult OSHAQuiz(Models.QuizSubmission model)
{
Then you'll be able to perform any actions you need for that quiz submission (ie. data access, validation ).
You'll also need to update your view so that your Html input elements have the correct name attributes that model binding can correctly bind each question and response pair to a QuizQuestionResponse item in your Responses list.

Model passed to Partial to View

Been searching around but couldn't find a direct solution to what I'm trying to achieve.
I've tried to include as much as needed but it's a very large project so hopefully you'll get the gist.
Overview:
I have a view model that has several lists of objects within it. I am using two partial views for control over each of the list of objects, one for gathering the list of objects (which is held in a session), and the other for adding a list of said object into the list.
Update:
As per comment - what I am looking to do is as follows - in the Index, fill out the existingIp model info, which is displayed through the addToListPartialView, then it will post to the ListPartialView to update the list through the session, handled backend in the controller, which will in turn display on the Index - the question ultimately is, how do I achieve this?
Problem:
The issue I'm having is once I've added an object, through a partial view, to the object list, another partial view, how do I then pass this back to the main view?
Code:
Controller
public ActionResult AddExistingIp([Bind(Include = "Subnet, Cidr, Mask")]ExistingIp existingIp)
{
if(Session["pa_ipv4Session"] != null)
{
pa_ipv4 pa_ipv4 = (pa_ipv4)Session["pa_ipv4Session"];
if(pa_ipv4.ExistingIps == null)
{
pa_ipv4.ExistingIps = new List<ExistingIp>();
}
pa_ipv4.ExistingIps.Add(existingIp);
ViewBag.pa_ipv4 = pa_ipv4.ExistingIps;
return View("ExistingIpView", ViewBag.pa_ipv4);
}
else
{
pa_ipv4 pa_ipv4 = new pa_ipv4();
Session["pa_ipv4Session"] = pa_ipv4;
pa_ipv4.ExistingIps = new List<ExistingIp>();
pa_ipv4.ExistingIps.Add(existingIp);
ViewBag.pa_ipv4 = pa_ipv4.ExistingIps;
return View("ExistingIpView", ViewBag.pa_ipv4);
}
Index:
#model ViewModel
<div id="ExistingIpList">
#{Html.RenderPartial("ExistingIpView");}
</div>
<div id="addExisting">
#{Html.RenderPartial("AddExistingIp");}
</div>
List Partial
#model IEnumerable<ExistingIp>
#if (Model != null)
{
foreach (var ei in Model)
{
<div class="ui-grid-c ui-responsive">
<div class="ui-block-a">
<span>#ei.Subnet</span>
</div>
<div class="ui-block-b">
<span>#ei.Cidr</span>
</div>
<div class="ui-block-c">
<span>#ei.Mask</span>
</div>
<div class="ui-block-d">
#ei.Id
Delete
</div>
</div>
}
}
Add to list partial:
#using (Html.BeginForm("AddExistingIp", "PA_IPV4"))
{
<div class="ui-grid-c ui-responsive">
<div class="ui-block-a">
<span>
#Html.EditorFor(m => m.Subnet)
#Html.ValidationMessageFor(m => m.Subnet)
</span>
</div>
<div class="ui-block-b">
<span>
#Html.EditorFor(m => m.Cidr)
#Html.ValidationMessageFor(m => m.Cidr)
</span>
</div>
<div class="ui-block-c">
<span>
#Html.EditorFor(m => m.Mask)
#Html.ValidationMessageFor(m => m.Mask)
</span>
</div>
<div class="ui-block-d">
<span>
#Html.EditorFor(m => m.Id)
#Html.ValidationMessageFor(m => m.Id)
</span>
</div>
</div>
<div data-role="main" class="ui-content">
<div data-role="controlgroup" data-type="horizontal">
<input type="submit" id="addExistingIp" cssclass="ui-btn ui-corner-all ui-shadow" value="Add" />
</div>
</div>
}
ViewModel:
public Contact ContactDetails { get; set; }
[Required]
public bool ExistingAddress { get; set; }
public List<ExistingIp> ExistingIps { get; set; }
[Required]
[DataType(DataType.MultilineText)]
public string ExistingNotes { get; set; }

You can modify the AddExistingIp to just store the data. And to make a RedirectToAction Index. There you will take the data from Session and pass it to the Model.
[HttpPost]
public ActionResult AddExistingIp([Bind(Include = "Subnet, Cidr, Mask")]ExistingIp existingIp)
{
if(Session["pa_ipv4Session"] != null)
{
pa_ipv4 pa_ipv4 = (pa_ipv4)Session["pa_ipv4Session"];
if(pa_ipv4.ExistingIps == null)
{
pa_ipv4.ExistingIps = new List<ExistingIp>();
}
pa_ipv4.ExistingIps.Add(existingIp);
}
else
{
pa_ipv4 pa_ipv4 = new pa_ipv4();
Session["pa_ipv4Session"] = pa_ipv4;
pa_ipv4.ExistingIps = new List<ExistingIp>();
pa_ipv4.ExistingIps.Add(existingIp);
}
return RedirectToAction("Index");
}
The Index Action will look similar with this, where you take data from Session and use it in your Model
public ActionResult Index()
{
var viewModel = new ViewModel();
// take data from Session
pa_ipv4 pa_ipv4 = Session["pa_ipv4Session"] as (pa_ipv4);
// some verification
// add the list from Session to model
viewModel.ExistingIps = pa_ipv4.ExistingIps;
return View(viewModel);
}
Also, I think your Index View you should at ExistingIpView you should pass the Model to display.
#model ViewModel
<div id="ExistingIpList">
#{Html.RenderPartial("ExistingIpView", Model.ExistingIps);}
</div>
<div id="addExisting">
#{Html.RenderPartial("AddExistingIp");}
</div>

Passing multiple Collections of data from View to Controller (ASP.NET MVC 5)

In a View i have the next structure ( control of Subject*s for each *Group):
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#for (int i = 0; i < ViewBag.AllGroups.Count; i++)
{
<h4>#ViewBag.AllGroups[i].Code</h4>
<select id="e-#i" multiple="multiple">
#foreach (Subject subject in ViewBag.AllSubjects)
{
<option value="#subject.Name">#subject.Name</option>
}
</select>
}
<input type="submit" value="Generate" class="btn btn-default" />
</div>
}
The question is that how can I retreive this data (I want to receive (1)list of Groups and and I want to get a (2)list of all selected Subjects for each group in my list(1)) in my Controller?
Thank you in advance.

Recommended way is to use strongly typed View Model Object
public class GroupViewModel
{
public string Code { get;set; }
public List<Subject> AllSubjects { get; set; }
}
Pass List as the Model to the Razor view in the controller.
return new View(new List<GroupViewModel>()); // populated one.
Use this list in the View.
#model IList<GroupViewModel>
#for (int i = 0; i < Model.Count; i++)
{
<h4>Model[i].Code</h4>
<select id="e-#i" multiple="multiple">
#foreach (Subject subject in Model[i].AllSubjects)
{
<option value="#subject.Name">#subject.Name</option>
}
</select>
}

There is nothing especial to deal with this situation, except that you have missed the tag name of the select element.
To be exact, all html elements such as select you have used here, should have a name not id (id="e-#i") and all elements are serialized based their names and sent to server. On the other side, at server-side, you should get the posted values which are in a csv formatted (due to multiple ability added you have added to select element)

Solved my problem by simplifying the task. What i had to to: I created new ViewModel for this thing. I replaced tag <select></select> with #Html.ListBoxFor(m => m.Subjects, Model.SubjectItems). I had to create a SubjectItems list in my ViewModel.
Here's the code (Sorry for tons of code: I just want to make everything clear):
My View:
#using System
#using System.Linq
#using TimeTable.GenericRepository
#model TimeTable.Models.GroupViewModel
#{
//it's better to move the next line to a Controller later
ViewBag.GroupId = new SelectList(new GroupRepository().Get().ToList(), "Id", "Code", Model.GroupId);
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_LayoutBootstrap.cshtml";
}
<h2>Index</h2>
<hr />
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#Html.ValidationSummary(true)
<div class="form-group">
#Html.LabelFor(model => model.GroupId, "Group is: ", new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("GroupId", String.Empty)
#Html.ValidationMessageFor(model => model.GroupId)
</div>
</div>
#Html.ListBoxFor(m => m.Subjects, Model.SubjectItems, new { #id = "e", #style = "width:80%; " })
<br /><br />
<input type="submit" value="Generate" class="btn btn-default" />
</div>
}
#* ReSharper disable once Razor.SectionNotResolved *#
#section Scripts {
#Styles.Render("~/Content/select2")
#Scripts.Render("~/bundles/select2")
<script type="text/javascript">
$(function () { $("#e").select2(); });
</script>
}
My Controller:
public ActionResult Generate()
{
return View(new GroupViewModel());
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Generate(GroupViewModel gvm)
{
var subjects= gvm.Subjects; // <== selected subjects are here
return View();
}
My Model:
public class GroupViewModel
{
public int GroupId{ get; set; }
public Group Group {
get { return new GroupRepository().GetById(GroupId); }
}
public object Subjects { get; set; }
public IEnumerable<SelectListItem> SubjectItems
{
get
{
var items = new SelectList(new SubjectRepository().Get().ToList(), "Id", "Name");
return items;
}
}
}
P.S. Select2 is a custom replacement for selectBoxes, it's not necessary, but I like it: http://ivaynberg.github.io/select2/

Partial View to Add Data

So here, I need to add comment for video in one view.
I have the main view code like this that displaying video and comment for that video.
<!-- language: C# -->
#model AzureMediaPortal.ViewModels.ViewModelWatch
#{
ViewBag.Title = "Watch";
}
<div id="videoPlayer">
</div>
<h2>#Html.DisplayFor(model => model.media.Title)</h2>
<h3> By #Html.DisplayFor(model => model.media.UserId) at #Html.DisplayFor(model => model.media.UploadDate) </h3>
#Html.HiddenFor(model => model.media.Id)
#Html.HiddenFor(model => model.media.AssetId)
#Html.HiddenFor(model => model.media.FileUrl, new { id = "fileUrl" })
<div class="display-label" style="font-weight:bold">
#Html.DisplayNameFor(model => model.media.Description)
</div>
<div class="display-field">
#Html.DisplayFor(model => model.media.Description)
</div>
<br />
<div class="display-label" style="font-weight:bold">
#Html.DisplayName("Category")
</div>
<div class="display-field">
#Html.DisplayFor(model => model.media.Category.CategoryName)
</div>
<h3>Comments</h3>
#foreach (var item in Model.comment)
{
<div class="display-label" style="font-weight:bold">
#item.UserId
</div>
<div class="display-field">

}
#Html.Partial("Post",new AzureMediaPortal.ViewModels.ViewModelWatch())
#section Scripts {
<script src="~/Scripts/playerframework.min.js"></script>
<script src="~/Scripts/media-player.js"></script>
#Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
mediaPlayer.initFunction("videoPlayer", $("#fileUrl").val());
</script>
}
and this the partial view
#model AzureMediaPortal.ViewModels.ViewModelWatch
#{
ViewBag.Title = "Post";
}
<h2>Add Comment</h2>
#Html.HiddenFor(model => model.cmnt.MediaElement.Id)
#using (Html.BeginForm("Post","Home",FormMethod.Post)) {
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>Add Comment</legend>
<div class="editor-label" style="font-weight:bold">
#Context.User.Identity.Name
</div>
<div class="editor-field">
#Html.TextAreaFor(model => model.cmnt.Content)
#Html.ValidationMessageFor(model => model.cmnt.Content)
</div>
<p>
<input type="submit" value="Post" />
</p>
</fieldset>
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
this is my ViewModel
public class ViewModelWatch
{
public MediaElement media { get; set; }
public List<Comment> comment { get; set; }
public Comment cmnt { get; set; }
}
and this is my controller
public ActionResult Watch(int id)
{
ViewModelWatch vm = new ViewModelWatch();
vm.media = _repository.GetMedia(id);
vm.comment = _repository.GetMediaComment(id);
return View(vm);
}
public ActionResult Post()
{
return View();
}
[HttpPost]
public ActionResult Post(Comment comment, int id)
{
if (ModelState.IsValid)
{
comment.UserId = User.Identity.Name;
comment.MediaElement.Id = id;
db.Comments.Add(comment);
db.SaveChanges();
return RedirectToAction("Watch");
}
return View();
}
I need to pass data from partial view and save it to database include the media.Id to know that comment inserted for the video.
Thanks so muchhh

putting scripts on a partial view is generally bad practice. Script gets inserted into the middle of the view. For saving information from a partial view I use ajax calls. To do that add a class to your post button
<input type="button" class="btnSubmit" value="Post" />
then in your script on the main page
$(document).on('click', '.btnSubmit', function(){
$.ajax({
url: '#Url.Action("Action", "Controller")',
cache: false,
async: true,
data: {
//put the data that you want to save from the partial here
id: $('#hiddenID').val(),
content: $('#Content').val()
},
success: function (_result) {
//can add something here like an alert, close a popup something along those lines
}
});
});
just make sure the inputs on your controller match exactly the names that you have defined here
[HttpPost]
public ActionResult Action(int id, string content){
//database call to save the fields
//see here for an example of returning json http://stackoverflow.com/questions/1482034/extjs-how-to-return-json-success-w-data-using-asp-net-mvc
return Json(json);

I would suggest using #Html.Action and get the create form from there. Also, once the comments are stored you can redirect to the parent action. That should automatically update the comments list.
But that would be a bad idea.
Rather you can put get your comments by calling action from ajax ($.ajax) and use pure.js to replace the older ones with the new comment list.
