Select multiple and display corresponding value from another model

I have Two different ASP.net Core 6.0 applications running that have tables linked to other tables by foreign keys. I create a CRUD for both pages. At the first CRUD (PriceList) page, I will enter the data. At the the second CRUD (CombineStage) of the page I will get the data (Stage) from the first page (Pricelist) using multiple select and the search box and its corresponding price in the Index page after using multiple select. I can't find any code commands to make this work. Any help would be appreciated. My foreign key is PricelistId. Below is my code:
CombineStage.cs
using System.ComponentModel.DataAnnotations;
namespace WebApp.Models
{
public class CombineStage
{
[Key]
public int StageId { get; set; }
[Required(ErrorMessage = "Bạn chưa nhập tên công đoạn")]
public string Name { get; set; }
[Required(ErrorMessage = "Bạn chưa chọn công đoạn")]
public int PricelistId { get; set; }
[Required(ErrorMessage = "Bạn chưa chọn ảnh")]
public string Picture { get; set; }
[Required(ErrorMessage = "Bạn chưa nhập giá tiền")]
public int Price { get; set; }
public virtual PriceList PriceList { get; set; }
}
}

Things I'm looking forward to
Next I will choose 2 option stages that I created
Next step, I want the total price of the 2 process options I have selected here
Finally, I want to show all the stages and prices of my 2 options that I have selected
That's all my request.

It's not entirely clear what you're expected result is with regard to records and their respective prices, but the binding code in your Create(CombinedStage, int[]) appears problematic given the PricelistId binding to CombinedStage. I would suggest creating a view model that reflects the form elements with an array/collection of simple values for PriceListIds in order for <select multiple>. For example, the new CombinedStageViewModel posted to the Create should have a property for `PricelistIds' such as the following for :
public IEnumerable<int> PricelistIds { get; set; }
Again, it's not entirely clear from the provided sample code or the accompanying description of the problem what the desired behavior is with respect to getting "...the entire corresponding Price value in Index Page." If you can post a sample project and define the expected results, it would make it much easier to provide a comprehensive answer to your question.

I made a simple test, you can refer to it.
I added a field to CombineStage to store your options:
public class CombineStage
{
[Key]
[ForeignKey("StageId")]
public int StageId { get; set; }
[Required(ErrorMessage = "Bạn chưa nhập tên công đoạn")]
public string Name { get; set; }
[Required(ErrorMessage = "Bạn chưa chọn công đoạn")]
[ForeignKey("PricelistId")]
public int PricelistId { get; set; }
[Required(ErrorMessage = "Bạn chưa chọn ảnh")]
public string Picture { get; set; }
[Required(ErrorMessage = "Bạn chưa nhập giá tiền")]
public int Price { get; set; }
public string PricelistIdList { get; set; }
public virtual PriceList PriceList { get; set; }

How to Get Selected List of DropDownList from Database or Model and Populate in Dropdown on View

I am performing a Bitwise-Create operation on my modal(view) and I am to select a dropdown list of users from another table/model and bind to the view so I can forward the request to them. I want to select users based on a certain role, if possible: but I just want to select the users from the database table.

Custom Validation Attribute not working in .NET 6

I have a model where I am trying to implement conditional validation. My few properties will be required only if the value for those properties are true in some other collection. I found some code here Conditional validation in MVC.NET Core (RequiredIf) but I am not understanding why it is not working in my case.
Expected case is, the validation should fire for "FirstName" field as it has true value in the collection and should not fire for Last Name field as it has false value in the collection. Currently validation is not firing at all for FirstName.
Here is my code:
Person.cs
public class Person
{
public int Id { get; set; }
//This property should be required only when this property exist in below class RequiredFieldsData.PropertiesPair() collection and has value true
[RequiredIf("FirstName", true, ErrorMessage = "First Name is required")]
public string FirstName { get; set; }
[RequiredIf("LastName", true, ErrorMessage ="Last name is required")]
public string LastName { get; set; }
}
public static class RequiredFieldsData
{
public static Dictionary<string, bool> PropertiesPair()
{
return new Dictionary<string, bool>
{
{"FirstName", true},
{"LastName", false }
};
}
}
[AttributeUsage(AttributeTargets.Property)]
public class RequiredIfAttribute : ValidationAttribute, IClientModelValidator
{
private string PropertyName { get; set; }
private bool DesiredValue { get; set; }
public RequiredIfAttribute(string propertyName, bool desiredValue)
{
PropertyName = propertyName;
DesiredValue = desiredValue;
}
protected override ValidationResult IsValid(object value, ValidationContext context)
{
object instance = context.ObjectInstance;
Type type = instance.GetType();
bool propertyValue = RequiredFieldsData.PropertiesPair().Any(t => t.Key == type.GetProperty(PropertyName).Name && t.Value == DesiredValue);
if (propertyValue && string.IsNullOrWhiteSpace(value?.ToString()))
{
return new ValidationResult(ErrorMessage);
}
return ValidationResult.Success;
}
public void AddValidation(ClientModelValidationContext context)
{
MergeAttribute(context.Attributes, "data-val", "true");
var errorMessage = FormatErrorMessage(context.ModelMetadata.GetDisplayName());
MergeAttribute(context.Attributes, "data-val-requiredif", errorMessage);
}

{

{
return false;

You have commented out the EmployeeImage, you only passed the EmployeeProfile to action, but
you didn't bind the EmployeeProfile.
Change to this:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("EmployeeName,EmployeeProfile,//***others")] EmployeeViewModel model)
Then I can upload the file using your code.
The [Bind] specifies which properties of a model should be included in model binding.Check:
https://learn.microsoft.com/en-us/aspnet/core/mvc/models/model-binding?view=aspnetcore-5.0#bind-attribute
whole code:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("EmployeeName,EmployeeProfile")] EmployeeViewModel model)
{
if (ModelState.IsValid)
{
string uniqueFileName = ProcessUploadedFile(model);
Employee employee = new Employee
{
EmployeeName = model.EmployeeName,
EmployeeImage = uniqueFileName
};
_context.Add(employee);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
return RedirectToAction("Index");
}
private string ProcessUploadedFile(EmployeeViewModel model)
{
string uniqueFileName = null;
if (model.EmployeeProfile != null)
{
string uploadsFolder = Path.Combine(webHostEnvironment.WebRootPath, "Uploads");
// uniqueFileName = Guid.NewGuid().ToString() + "_" + model.EmployeeProfile.FileName;
uniqueFileName = Guid.NewGuid().ToString() + "_" + Path.GetFileName(model.EmployeeProfile.FileName);
string filePath = Path.Combine(uploadsFolder, uniqueFileName);

Bundle IdentityUser to ticket

This is a homework assignment. Where I have to make a website with MVC 2.2 and Make it possible to make a ticket with some basic info and link IdentityUser to the ticket.
The Class:
public class Ticket
{
public int ID { get; set; }
[Required]
public string Klant { get; set; }
[Required]
public string Applicatie { get; set; }
[Required]
public string Onderwerp { get; set; }
[Required]
public string Omschrijving { get; set; }
public DateTime Datum { get; set; }
public string Status { get; set; }
}
The Controller:
public class TicketsController : Controller
{
private readonly ApplicationDbContext _context;
UserManager<IdentityUser> _userManager;
public TicketsController(UserManager<IdentityUser> userManager)
{
_userManager = userManager;
}
public TicketsController(ApplicationDbContext context)
{
_context = context;
}
// GET: Tickets
public async Task<IActionResult> Index()
{
return View(await _context.Ticket.ToListAsync());
}
This is added to the controller at the moment.
UserManager<IdentityUser> _userManager;
public TicketsController(UserManager<IdentityUser> userManager)
{
_userManager = userManager;
}
So I was asking myself how to do this and I would really appreciate it if someone knows what to do and can explain it well.
Thanks in advance.
If you need more info just ask.

Here is a working scenario for creating one ticket with one IdentityUser.
