Can't load image to partial view in edit view

In my application, previously I had issue with loading data to the partial view. With help I resolved that it. But still there is some issue here. Now when create the request I use this partial view to add data and image for user.
#model Asp_PASMVC.Models.GeneralItms
#using Asp_PASMVC.Infrastructure
#{
var z = Model.Attachment_Description;
var a = Model.Attachment_Amount;
var x = Model.Attachment;
}
<li style="padding-bottom:15px">
#using (Html.BeginCollectionItem("GeneralItmsList"))
{
#Html.HiddenFor(model => model.TempID)
<div class="form-horizontal" id="quickForm" novalidate="novalidate">
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="row">
<div class="col-md-5 col-sm-6">
<div class="form-group">
Select Item Description
<div class="col-md-10">
#Html.EditorFor(model => model.Attachment_Description, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Attachment_Description, "", new { #class = "text-danger" })
</div>
</div>
</div>

</div>
#Html.ValidationMessageFor(model => model.Attachment_Amount, "", new { #class = "text-danger" })
</div>
</div>
</div>
<div class="col-md-3 col-sm-6">
<div class="form-group">

<div class="col-md-10">
<input type="file" name="ImageData#(Model.TempID.ToString())" id="ImageData#(Model.TempID.ToString())" multiple="multiple" data-id="Img#(Model.TempID.ToString())" onchange="checkImage(this)" />
#Html.ValidationMessageFor(model => model.Attachment, "", new { #class = "text-danger" })
</div>
</div>
<img id="Img#(Model.TempID.ToString())" src="" alt="" width="100" height="100" class="ml-1" />
</div>
<button type="button" class="btn btn-danger" onclick="$(this).parent().remove();">Remove</button>
</div>
</div>
}
</li>
<script type="text/javascript">
$('.js-dropdown').select2({
width: '100%', // need to override the changed default
});
function checkImage(obj) {
var fileExtension = ['jpeg', 'jpg', 'png', 'gif', 'bmp'];
var ResponceImgId = $(obj).data('id');
if ($.inArray($(obj).val().split('.').pop().toLowerCase(), fileExtension) == -1) {
alert('error', 'Upload Error', 'Only .jpeg, .jpg, .png, .gif, .bmp formats are allowed.');
}
else {
var files = obj.files;
var reader = new FileReader();
name = obj.value;
reader.onload = function (e) {
$('#' + ResponceImgId).prop('src', e.target.result);
};
reader.readAsDataURL(files[0]);
}
}
</script>
When creating the request in the controller I have code like this
if (appRequest.GeneralItmsList != null)
{
foreach (GeneralItms item in appRequest.GeneralItmsList)
{
HttpPostedFileBase file = Request.Files["ImageData" + item.TempID];
item.Attachment = ConvertToBytes(file);
}
appRequest.General = new List<General>()
{
new General
{
GeneralItms = appRequest.GeneralItmsList,
}
};
}
and this method will convert the image to byte and pass to the controller to submit the data.
public ActionResult RetrieveImageG(int id)
{
var q = from temp in db.GeneralItms where temp.Id == id select temp.Attachment;
byte[] cover = q.First();
if (cover != null)
{
return File(cover, "image/jpg");
}
else
{
return null;
}
}
So Crete is working fine, and when in the edit view, I again called the same partial view to load the data inside the edit main view.
It's has 3 fields. Item Description , Amount and the attachment.
So It's loading the Item Description and amount properly, and it won't load the image again. Within the partial view I have put
#{
var z = Model.Attachment_Description;
var a = Model.Attachment_Amount;
var x = Model.Attachment;
}
to check is data passing to the view. attachment is shown in the Model.Attachment. But it won't show in the view. Can I get a help on this?

if you already happen to have the image loaded in your model: doing this way you can display the image
<img src="data:image;base64,#System.Convert.ToBase64String(Model.Attachment)" />

i dont know why but i am getting this 500 error resource cannot found for this method.

How to pass dropdown value to controller in mvc? [duplicate]

This question already has answers here:
How to get DropDownList SelectedValue in Controller in MVC
(9 answers)
Closed 5 years ago.
I am working on bulk sms in mvc. I have a view named SendSMS where i have fields like Sender ID, Numbers, Messagetext. Here, I am getting value of SenderID from Sender table where it consists Sender ID, Sender Name. Before sending message, user will add Sender Name from different view. As of now, I have added Sender Name. I am able to display Sender Name using dropdownList in SendSMS view.
After creating Sender ID and Sender Name, User enters SendSMS view to send Message. User will select Sender Name using dropdown list. He will add Numbers and Message text. When user clicks on Send button, the dropdown value is to passing to controller.
Here is the view code:

Passing a List of objects from Razor View to Controller only passes one item instead of the whole list

I want to pass a List of VoedingBindingModel to my controller by using an Editor Template, however I only receive the first entry of the List in the Controller, never all the entries.
The Controller:
public ActionResult Create()
{
ViewBag.fk_customVoedingId = new SelectList(customvoeding.GetAllCustomvoeding(), "customVoedingId", "customVoedingNaam");
ViewBag.fk_standaardVoedingId = new SelectList(standaardvoeding.GetAllStandaardvoeding(), "standaardVoedingId", "standaardVoedingNaam");
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,Datum,Tijd,VoedingCollection")]AgendaBindingModel agendaBindingModel)
{
//Do something
}
The Model:
public class AgendaBindingModel
{
[Required]
public List<VoedingBindingModel> VoedingCollection { get; set; }
//More properties
}
The View:
#using Website.Models
#model AgendaBindingModel
#using (Html.BeginForm())

<div class="form-horizontal">

Partial class:
(customvoeding and standaardvoeding do the same thing, only customvoeding returns a collection of customvoeding and standaardvoeding returns a collection of standaardvoeding.
public partial class customvoeding
{
private static foodtrackerEntities1 db = new foodtrackerEntities1();
public static List<customvoeding> GetAllCustomvoeding()
{
db.Configuration.LazyLoadingEnabled = false;
return db.customvoeding.ToList();
}
}

You don't seem to be initializing the model and passing it to the view. In the action methods of your controller try adding:
var viewModel = new AgendaBindingModel();
viewModel.VoedingCollection = // TODO: Fill the list from your data source
return View(viewModel );

Try like this. I could not test, but if you like we can advance is this way:
To show all items:
<div id="group">
#for(int i = 0; i < AgendaBindingModel.VoedingCollection.Count; i++)
{
#Html.EditorFor(x => x.VoedingCollection[i])
}
To add new item:
<button onclick=newItem() >+</button>
</div>
<script>
function newItem(){
var div = document.createElement('div');
div.id = CreateNewItem;
div.innerHTML = '#Html.EditorFor(x => x.VoedingCollection[i])';
document.body.appendChild(div);
}
</script>

Your second and third html are broken.
<div id="CreateVoedingDiv2"hidden>
remove hidden

I found out what was preventing me from receiving more than one result:
You can NOT use #Html.EditorFor template for more than 1 value when you specify a template. It does not matter if you use different models or different templates, it just simply does not work.
To fix it, you have to use 'Html.BeginCollectionItem' library, which can be found here.

Overtime the page loads the Validation message shows for InterestName in the second form AddInterest.
The Get method for the whole form is:
[HttpGet]
public ActionResult NewInterests(NewClubInterestsViewModel model, int id)
{
//Find the Club and then pass its id to the ViewModel
var club = db.Clubs.Find(id);
//model.ClubId = club.ClubId ;
//Interests List
IEnumerable<Interest> allExistingInterests;
//Generate a list of the interests that apply to that type of club
using (ApplicationDbContext context = new ApplicationDbContext())
{
allExistingInterests = context.Interests
.Where(s => s.ClubTypeId == club.ClubTypeId)
.OrderBy(s => s.InterestName)
.ToList();
}
IEnumerable<int> clubInterestIds = club.ClubInterests.Select(x => x.InterestId).ToList();
//Generate the ViewModel with the appropriate Interests
var viewModel = new NewClubInterestsViewModel
{
ClubId = club.ClubId,
Name = club.Name,
ClubTypeId = club.ClubTypeId,
ClubTypeInterests =
allExistingInterests.Select(
x => new ClubInterestsViewModel { InterestId = x.InterestId, InterestName = x.InterestName, selected = clubInterestIds.Contains(x.InterestId) }).ToArray()
};
return View(viewModel);
}
What do I need to do to stop the validation message showing on load?

Remove the NewClubInterestsViewModel model parameter from your GET method. It should be just
public ActionResult NewInterests(int id)
The first step in the model binding process is that instances of your parameters are initialized and then its properties are set based on form values, route values, query string values etc. In your case there are no values to set, so the properties of your model are their defaults, but because you have validation attributes on your properties, validation fails and errors are added to ModelState which are then displayed in the view.
