How do I pass a selected ID to my SQL Database?

I am having trouble with this last part of my project. I have all of my SQL Table columns filled up except for this last part. I have two tables WorkSchedule and WorkShiftBid.
In WorkShiftBid, I have WorkShiftBidID,WSBidDateTime,WSBidStatus,WorkScheduleID,StaffID
I will be using Guid.NewGuid() for WorkShiftBidID, Datetime.now for WSBidDatetime, A hardcoded "pending" value for WSBidStatus, A viewbag for StaffID and I am trying to get the WorkScheduleID to work but to no avail.
For WorkSchedule, I am trying to get just the "WorkScheduleID" attribute just by using a button method asp-route-id="#item.WorkScheduleID" and it will redirect me to the Create page whereby I will select a Staff from the drop-down list and then save it to my WorkShiftBid table as it has a foreign key for "WorkScheduleID".
It would be helpful if someone could help me. Thank you.
Controller Code:
public IActionResult CreateWorkShift()
{
ViewData["StaffID"] = new SelectList(_context.Staff, "StaffID", "StaffName");
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> CreateWorkShift(Guid? id, [Bind("WorkShiftBidID,WSBidDateTime,WSBidStatus,WorkScheduleID,StaffID")] WorkShiftBidModel workShiftBidModel)
{
if (id != workShiftBidModel.WorkScheduleID)
{
return NotFound();
}
if (ModelState.IsValid)
{
workShiftBidModel.WSBidDateTime = DateTime.Now;
workShiftBidModel.WorkShiftBidID = Guid.NewGuid();
_context.Add(workShiftBidModel);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(DisplaySchedule));
}
ViewData["StaffID"] = new SelectList(_context.Staff, "StaffID", "StaffName", workShiftBidModel.StaffID);
return View(workShiftBidModel);
}
private bool WorkShiftBidModelExist(Guid id)
{
return _context.WorkSchedule.Any(e => e.WorkScheduleID == id);
}

Do you mean you cannot get the WorkScheduleID in public async Task<IActionResult> CreateWorkShift(Guid? id, [Bind("WorkShiftBidID,WSBidDateTime,WSBidStatus,WorkScheduleID,StaffID")] WorkShiftBidModel workShiftBidModel).If so,you need to get and pass Id in public IActionResult CreateWorkShift.Here is a demo worked:
public IActionResult CreateWorkShift(int id)
{
List<Staff> list = new List<Staff> { new Staff { StaffID = 1, StaffName = "staff1" }, new Staff { StaffID = 2, StaffName = "staff2" } };
ViewData["StaffID"] = new SelectList(list, "StaffID", "StaffName");
WorkShiftBidModel w = new WorkShiftBidModel { WorkScheduleID = id };
return View(w);
}
result:

could not update or edit the specific data in the HTTP post method

I wanted to update the quantity value. for that, I am using the HTTPPost method of the index for update quantity. but it's could not because of error.
here is my code:
public IActionResult Index()
{
return View(_db.Shop.Include(c => c.Category).Include(f => f.SubCategory).ToList());
}
[HttpPost]
public IActionResult Index(int? id)
{
var product = _db.Shop.Where(x => x.Id == id).FirstOrDefault();
IndexVm ji = new IndexVm
{
Id = product.Id,
Image = product.Image,
Image1 = product.Image1,
Quantity = product.Quantity++,
Price = product.Price,
PreviousPrice = product.PreviousPrice,
Description = product.Description,
};
_db.Shop.Update(ji);
_db.SaveChanges();
return RedirectToAction(nameof(Index));

I want something like that.

I am beginner, please anyone help.

You should use:
var product = _db.Shop.AsNoTracking().Where(x => x.Id == id).FirstOrDefault();
You are fetching product but updating new instance ji with the same id. Since the id is the same, EF thinks that those are two objects with same primary key which should not happen, thus error.
Your other option would be to update product that you fetched from the database:
[HttpPost]
public IActionResult Index(int? id)
{
var product = _db.Shop.Where(x => x.Id == id).FirstOrDefault();
product.Quantity++;
_db.Shop.Update(product);
_db.SaveChanges();
return RedirectToAction(nameof(Index));
}
You can find more about this here: https://learn.microsoft.com/en-us/ef/core/querying/tracking

You are doing these two mistakes:
You are passing VM to update function which is wrong.
To update any existing EF object, you have to update that object instead of creating new.
{
var product = _db.Shop.Where(x => x.Id == id).FirstOrDefault();
product.Quantity++;
_db.Shop.Update(product);
_db.SaveChanges();
return RedirectToAction(nameof(Index));
}

How to add a counter with row numbering on all site in mvc

I want to add an automatic numbering of order items to all pages.
Below is an example that works but only numbers on one page. After going to the next page, it starts from the beginning.
public ActionResult ListaZlecen(int? IdStatusZlecenia, int strona = 1)
{
var ListaZlecenWszystkich = db.Zlecenia.ToList();
var userId = User.Identity.GetUserId();
//var ListaZlecen = db.Zlecenia.Where(p => p.UserId == userId).ToList();
//var ListaZlecen = db.Zlecenia.OrderBy(w => w.IdZlecenia).Where(p => p.UserId == userId).Skip((strona - 1) * WielkoscStrony).Take(WielkoscStrony).ToList();
var ListaZlecen = db.Zlecenia.OrderBy(w => w.IdZlecenia).Skip((strona - 1) * WielkoscStrony).Take(WielkoscStrony).ToList();
// var zleceniezalacznik = db.ZleceniaZalaczniki.ToList();
var viewodel = new ListaZlecenUzytkownikaViewModel()
{
StronaInfo = new StronaInfo
{
AktualnaStrona = strona,
PozycjeNaStrone = WielkoscStrony,
WszystkiePozycje = ListaZlecenWszystkich.Count()
},
ListaZlecenUzytkownika = ListaZlecen
};
return View(viewodel);

I tried this way but it creates numbering only on one page. Going to the next numbering is created from the beginning.
#{ var i = 0;}
<td>
#{i++;}
#i
</td>
I have 3 orders on each page and I would like all orders to be automatically numbered, for example:
First page 1,2,3
Second page 4,5,6
I am asking for help in creating the numbering for the entire collection of orders

Instead of starting at i=0 you can start at your current page,
I don't know which language it is but I hope i got it right.
// Instead of this: #{ var i = 0;} - on your view
//Use this:
#{ var i = (Model.AktualnaStrona -1 ) * Model.PozycjeNaStrone ;}
//It should be equal to the calculation you use on the API:
(strona - 1) * WielkoscStrony
//(from this line: )
var ListaZlecen = db.Zlecenia.OrderBy(w => w.IdZlecenia).
Skip((strona - 1) * WielkoscStrony). //--> THIS
Take(WielkoscStrony).ToList();

When Run i got this error
The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery1
,but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[MvcMarks.Models.MarksType]'

Change return statement to
return View(query
.Select(it => new MarksType{
//initilize properties of `MarksType` with `it`
}));
Your view expects a model of type IEnumerable<MarksType> but query variable is IEnumerable of Anonymous objects.

thanks.

Make sure inside your view you have input fields for all values that you intend to use in your POST action. For example if you want to use the ceremony_id, first_name, middle_name, and last_name properties you need to include them:
#Html.HiddenFor(model => model.ceremony_id)
#Html.HiddenFor(model => model.first_name)
#Html.HiddenFor(model => model.middle_name)
#Html.HiddenFor(model => model.last_name)
You could use hidden fields if the user is not supposed to modify their values but you could also have used text fields depending on your requirements.
