ASP.NET core get route data values into input box

Question

I have a razor view in which a person's information are displayed, it route is https://localhost:PORT/Pesron/Details/E-12345.

I want to create a profile for the said person using another controller, the corresponding link would be https://localhost:PORT/Profile/Create/E-12345.

The page would open normally, but I would like getting the value E-123456 which is the person's ID and obviously changes from one to another, into a (disabled) input box in Create, so when I fill other information and press submit, a new profile is created, I am doing it using MVC controller but wouldn't mind using Web API too. How I open Create in Person's Details view.

<a asp-action="Create" asp-controller="Profile" asp-route-id="@Model.ID">Create</a>

My 2 Create action methods.

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> Create(string MRN, [Bind("Id,Dep_Id,Check_In,Check_Out")] Profile profile)
        {
            ViewData["ID"] = MRN;


            if (ModelState.IsValid)
            {
                _context.Add(profile);
                await _context.SaveChangesAsync();
                return RedirectToAction(nameof(Index));
            }


            return View(profile);
        }

        public IActionResult Create(string MRN)
        {
           ViewData["ID"] = MRN;

            return View();
        }

Could the reason be that the value I am sending is not the primary key, I made it hidden and auto incrementing.

You should use asp-route-MRN="@Model.ID". Change your code to <a asp-action="Create" asp-controller="Profile" asp-route-MRN="@Model.ID">Create</a> — Yinqiu

Does putting MRN in the Bind() have anything to do with it? — user10191234

You can use ViewData.Below is an example.

View:

<a asp-action="Create" asp-controller="Profile" asp-route-id="@Model.ID">Create</a>

Create action:

 public IActionResult Create(string id)
    {
        ViewData["ID"] = id;

        return View();
    }

Create View:

 <input value="@ViewBag.ID" disabled="disabled"/>

Post Create method:

 [HttpPost]
    public IActionResult Create(Profile profile, string id)
    {
        //.....
        return RedirectToAction("actionname","Controllername");
    }

Not working, also trying @ViewData["ID"], not working too.

Where does it not work? Is the correct id not displayed in the input box?

Yes, the input box is blank.

Hit a breakpoint in your Create action, observe whether the id is successfully bound, and make sure that <input value="@ViewBag.ID" disabled="disabled"/> is in your Profile/Create view.

You can see my test.
