Multiple Models Update POST method does not work in MVC

Multiple Models Update POST method does not work in MVC - c#

I've this Update ActionResult and It does not work as it should be because it does not get the Id values from PartialView on button click as of that on saveChange code breaks
Here is my Method and Let me explain the method:
This method is receiving two models at the same time One is from the Main View and the second from PartialView and the model in PartialView is of type List. In case of save they work perfect but not in the case of update
[HttpPost]
public ActionResult ManpowerEdit(ViewModelsManpowerEdit model, int projectId)
{
db.Configuration.ProxyCreationEnabled = false;
var manpower = db.PMCManpowerRequests.Find(model.ModelManpowerRequestEdit.Id);
int id = model.ModelManpowerRequestEdit.Id;
manpower.ProjectId = projectId;
manpower.JobNo = model.ModelManpowerRequestEdit.JobNo;
manpower.RequestDate = model.ModelManpowerRequestEdit.RequestDate;
db.Entry(manpower).State = EntityState.Modified;
db.SaveChanges();
foreach (var result in model.ModelManpowerRequestEditResults)
{
db.PMCManpowerRequestDetails.AddOrUpdate(
new PMCManpowerRequestDetail()
{
ManpowerRequestId = model.ModelManpowerRequestEdit.Id,
ManpowerId = result.ManpowerId,
Planned = result.Planned,
Actual = result.Actual,
Remarks = result.Remarks
});
}
db.SaveChanges();
return RedirectToAction("Index", "PmcManpowerRequestDetail");
}
and this is my PartialView
#model ProjectManagementSystem.ViewModel.ViewModelsManpowerEdit
<table class="table table-responsive table-striped">
<tr class="row">
<th> Manpower Type</th>
<th> Planned</th>
<th> Actual</th>
<th> Remarks</th>
</tr>
#for (int i = 0; i < Model.ModelManpowerRequestEditResults.Count; i++)
{
<tr class="row">
<td>
#Html.EditorFor(m => m.ModelManpowerRequestEditResults[i].ManpowerType,
new { htmlAttributes = new { #readonly = "readonly", #class = "form-control" } })
#Html.HiddenFor(m => m.ModelManpowerRequestEditResults[i].Id)
</td>
<td>
#Html.EditorFor(m => m.ModelManpowerRequestEditResults[i].Planned,
new { htmlAttributes = new { #class = "form-control" } })
</td>
<td>
#Html.EditorFor(m => m.ModelManpowerRequestEditResults[i].Actual,
new { htmlAttributes = new { #class = "form-control" } })
</td>
<td>
#Html.TextBoxFor(m => m.ModelManpowerRequestEditResults[i].Remarks,
new { type = "text", #class = "form-control" })
</td>
</tr>
}
</table>
and Down Here is my Main View
#model ProjectManagementSystem.ViewModel.ViewModelsManpowerEdit
<style>
h2 {
color: #b48608;

<div class="form-group">
<input type="submit" id="Save" value="Update" class="btn btn-success" />
</div>
My view models public class ViewModelsManpowerEdit
{
public PmcManpowerRequestViewModel ModelManpowerRequestEdit { get; set; }
public List<ManpowerRequestEdit_Result> ModelManpowerRequestEditResults { get; set; }
}

All I can see after reading your comments is the Id's are null so I will suggest add the respected Id's in Hidden Fields in their respected Views and Partial Views
For example: as you haven't provided any model all I can do is predict
#Html.HiddenFor(m => m.ModelManpowerRequestEditResults[i].ManpowerId)
#Html.HiddenFor(m => m.ModelManpowerRequestEditResults[i].Id)
#Html.HiddenFor(m => m.ModelManpowerRequestEditResults[i].ManpowerrewuestId)
Because you said ManpowerId and Id and ManpowerrewuestId

Dynamic Add and Edit of Data in Asp.net Mvc using Razor view

I'm new to MVC. Using the scaffolding mechanism I have managed to create CRUD operations on the database table. This works well with working on a single MVC Model at a time (Mapped to a single Model). I want to implement add & edit of a List into database (will be empty list initially), the user should be able to add as many number of items as he need and then submit the data to the database. I want this list to be of dynamic length, so that when user edits the data he should be able to add few more new elements into the Model also deleting few individual Model. I couldn't find proper resource to come up with a solution. Little help will be much Appreciated.
Scenario - Person can have multiple Addresses or Person will not be having any addresses. How to add multiple Address by adding addresses into the view and how to perform edit on those? If one of the Address needs to be deleted then how to do so?
Thank you.

I'm using Web API for the backend process. I have added a delete and Add New Row button in the view for Address tab. For now it is working with just a single Model, I wanted to know how to implement it for a Dynamic list, So as to A Person can have 'n' number of Addresses and he can edit whichever he want and also delete based on AddressId. I know the code seems quite low rated. Just want to know the syntax and semantics on how to proceed with working on List. Sorry for Messing up things. Thank you.

Got a solution from Matt lunn.
Follow this link :-
https://www.mattlunn.me.uk/blog/2014/08/how-to-dynamically-via-ajax-add-new-items-to-a-bound-list-model-in-asp-mvc-net/
It is implemented by using custom HtmlHelper Extension and creating Html.EditorForMany().
Thanks a lot for the trick Matt Lunn. Works Exactly How I wanted. :)

How to use pagedlist with post method

I have a question about PagedList. I have a grid of data that I can filter using dropdownlist and checkbox. It works well. I use "PagedList", which allows me to display only 10 row per page in my grid of data. It works well when I don't use filter. When I select an item in my dropdownlist for example, the filter works well in the first page but if I click on the 2nd page the filter doesn't work anymore. To filter data, I use method Post and ViewModel. What can I do?
Thanks!

1) If you are willing to revamp and modify your code both server side and client-side, I recommend following instructions mentioned at this tutorial
2) In case you want to use Post method then, following changes may help you:
In your server side code, wherever you are assigning an object to 'ViewBag.searchItem', try using TempData["searchItem"] in place of it. And when accessing it on View page, also use TempData["searchItem"] wherever you are accessing 'ViewBag.searchItem' with appropriate casting.
While I suppose your server side code is working, client side html may work as shown below, with form tag wrapped around entire HTML..

Thanks, I found the solution. I decided to use only get method.
In my controller I have this:
public ActionResult Index(string SortOrder, int? page, string ProgrammeIdSelected)
{
IndexViewModel model = new IndexViewModel();
//Affichage de la liste des Programmes
model.Programme = GetProgrammes();
//Tri des pays:
model.SortCountry = String.IsNullOrEmpty(SortOrder) ? "ListorderPays_desc" : "";
model.ProgrammeIdSelected = ProgrammeIdSelected;
model.missionsList = db.missions_supportmission.ToList();
switch (SortOrder)
{
case "ListorderPays_desc":
model.missionsList = model.missionsList.OrderByDescending(s => s.organization_hi_country.name_en);
break;
default:
model.missionsList = model.missionsList.OrderBy(s => s.organization_hi_country.name_en);
break;
}
//Pagination
var pageNumber = page ?? 1; // if no page was specified in the querystring, default to the first page (1)
var onePageOfMissions = model.missionsList.ToPagedList(pageNumber, 10); // will only contain 10 products max because of the pageSize(equel to 10)
model.OnePageOfMissions = onePageOfMissions;
//Ischecked
var allDecisions = db.list_decision.ToList();//returns List<list_decision>
var checkBoxListItems = new List<CheckBoxListItem>(); //nouvelle instance de la classe checkboxlist
foreach (var decison in allDecisions)
{//On assigne les valeurs "id", "display" et "is checked" à la variable checkboxlistitem
checkBoxListItems.Add(new CheckBoxListItem()
{
ID = decison.decision_id,
Display = decison.name_en,
IsChecked = false //On the add view, no decision are selected by default
});
}
//Si Programme n'est pas null et que country est null
if (!String.IsNullOrEmpty(ProgrammeIdSelected))
{
model.OnePageOfMissions = db.missions_supportmission
.Where(a => a.programme_id == ProgrammeIdSelected)
.OrderBy(a => a.programme_id)
.Select(s => s).ToPagedList(pageNumber, 10);
}
return View(model);
}

Step wizard in Asp.Net MVC unintentionally validating with prev button

I'm following this guide here to create a step wizard to traverse multiple pages with forms on each while saving each forms data to store in my db but the problem I'm having is on the second page 'addressDetails'. When I press the prevBtn to return to the previous page 'basicDetails', my form is trying to do client side validation and I get all the validation errors instead of posting to my action method to see whether the prevBtn or nextBtn was pressed
Here is my addressDetails page
<div class="col-sm-7 col-sm-offset-1">
#using (Html.BeginForm("AddressDetails", "User", FormMethod.Post)) {
<div class="row">
<h3>What's the address for this payout method?</h3>
</div>
<div class="row">
<div class="form-group">

#Html.TextBoxFor(m => m.StreetAddressLine1, new { #id = "AddressLine1", #class = "form-control input-lg", placeholder = "e.g. 123 Main St." }) #Html.ValidationMessageFor(m => m.StreetAddressLine1,

</div>
<div class="row">

</div>

<div class="form-group">

<div class="row">

</div>
<div class="row">
<div class="col-sm-12">
<input type="submit" name="prevBtn" value='Previous' />
<input type="submit" name="nextBtn" value='Next' />
</div>
</div>
}
</div>
Here is my action method
[HttpPost]
public ActionResult AddressDetails(UserAddressViewModel addressViewModel, string prevBtn, string nextBtn)
{
YogaProfileBankAccount obj = GetBankAccount();
if (prevBtn != null)
{
UserBillingViewModel billingViewModel = new UserBillingViewModel();
//bd.CustomerID = obj.CustomerID;
//bd.CompanyName = obj.CompanyName;
return View("BasicDetails", billingViewModel);
}
if (nextBtn != null)
{
if (ModelState.IsValid)
{
//obj.Address = data.Address;
//obj.City = data.City;
//obj.Country = data.Country;
//obj.PostalCode = data.PostalCode;
return View("AccountDetails");
}
}
return View();
}
So here is what happens when I press previous, all the fields try to get validated

MVC view data passing

I am making my MVC application. My view PickGroupForHomework is redirected to by
return RedirectToAction("PickGroupForHomework", "Account", new { subject_id = id, qty=model.qty });
Of course subject_id and qty are parameters of PickGroupForHomeworkViewModel. The controller looks like this:
public ActionResult PickGroupForHomework(PickGroupForHomeworkViewModel model)
{
ClassDeclarationsDBEntities2 entities = new ClassDeclarationsDBEntities2();
model.groups = entities.Groups.ToList();
model.users = entities.Users.ToList();
int id = model.subject_id;
var subj = entities.Subjects
.Where(b => b.class_id == model.subject_id)
.FirstOrDefault();
if (subj != null)
{
model.subject_name = subj.name;
}
if (ModelState.IsValid)
{
DateTime myDate = DateTime.ParseExact(model.deadline+ " "+model.time, "yyyy-MM-dd HH:mm",
System.Globalization.CultureInfo.InvariantCulture);
ClassDeclarationsDBEntities2 entities2 = new ClassDeclarationsDBEntities2();
int total = entities2.Tasks.Count();
for (int i=0;i<model.task_names.Count;i++)
{
ClassDeclarationsDBEntities2 entities3 = new ClassDeclarationsDBEntities2();
int maxid;
if (total == 0)
{
maxid = 0;
}
else {
maxid = entities3.Tasks.Max(u => u.task_id);
}
var task = new Models.Task(model.task_names[i], model.subject_id, myDate, model.points[i], maxid + 1);
entities3.Tasks.Add(task);
entities3.SaveChangesAsync();
}
return RedirectToAction("OperationSuccess", "Account");
}
else
{
return View(model);
}
return View(model);
}
At first, everything loads correctly with correct URL including data passed from previous view. The form I am displaying now includes validation. If a user makes mistake in form, which indicades ModelState.IsValid=false, the window is reloaded. But I do not know why it is reloaded without data passed from previous window: subject_id and qty. What am I doing wrong?

Your problem is subject_id is not in your form, so when you post back the form it sends 0 value to the server.
you need to add a field inside form , you can add a Text or hidden field
#Html.HiddenFor(m => m.subject_id)

mvc pagedlist date loses value on second page

I have an Index page with various filtering options on it, all included within a PagedList. They all appear to be working fine, except for the dates.
When I first filter by date, they work fine however when I click on a page number at the bottom, the search criteria for my date is disappearing.
I can see that I can passing the search term in the paged list, and I can see this date hit my controller and the filtering happen but the ViewBag.filterStartDate and ViewBag.filterEndDate just aren't binding back to my textboxes for some reason.

#Html.TextBox() can pull values out of the ModelState or ViewData.
Try building the html for the date input manually like this:
<input type="date" name="filterStartDate" id="filterStartDate" class="form-control date" value="#ViewBag.filterStartDate.ToString("yyyy-MM-dd")"/>

Resolved the issue by manually creating the date inputs rather tahn relying on Razor to do it for me!
#if (ViewBag.filterStartDate != null)
{
<input type="date" name="filterStartDate" id="filterStartDate" value="#ViewBag.filterStartDate.ToString("yyyy-MM-dd")" />
}
else
{
<input type="date" name="filterStartDate" id="filterStartDate" value="" />
}
