dotnet 5 MVC 404 error when I post to action

I have a page that is supposed to submit data for a patient evaluation. The page to submit the evaluation comes up fine. It is based on a ViewModel. Here is the ViewModel:
public class SPEPatientEvalVM
{
public int Id { get; set; }
public int ApptId { get; set; }
public int ActivityID { get; set; }
public int VendorID { get; set; }
public int PatientID { get; set; }
[Required(ErrorMessage ="A selection is required.")]
public int OverallRating { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int AppearProfessComp { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int EffGatheredInfo { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int ListenActively { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int EstabPersRapport { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int AppropExploreMyFeelings { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int AddressedMyFeelings { get; set; }
[Required(ErrorMessage = "A selection is required.")]
public int MetMyNeeds { get; set; }
public string PatientComments { get; set; } = String.Empty;
public DateTime DateSubmitted { get; set; }
}
This is mapped and reverse mapped to the model using IMapper.
Anyway this is my controller code:
[HttpGet("[controller]/[action]/{IDAppt}/{ActivityID}/{VendorID}/{PatientID}")]
public async Task<IActionResult> AddSPEPatientEval(int IDAppt, int ActivityID, int VendorID, int PatientID)
{
var patientChoice = GetPatientChoiceList();
patientChoice[0].Selected = true;
ViewBag.PatientChoice = patientChoice;
var evalParams = await _speRepo.GetOpenPatientEval(IDAppt);
ViewBag.Patient = evalParams.SPEPatient;
var speEval = new SPEPatientEvalVM
{
ApptId = IDAppt,
ActivityID = ActivityID,
VendorID = VendorID,
PatientID = PatientID
};
return View(speEval);
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> AddSPEPatientEval(SPEPatientEvalVM model)
{
var patientChoice = GetPatientChoiceList();
patientChoice[0].Selected = true;
ViewBag.PatientChoice = patientChoice;
model.DateSubmitted = DateTime.Now;
if (ModelState.IsValid)
{
var spePatientEval = _mapper.Map<SPEPatientEval>(model);
var success = await _speRepo.AddSPEPatientEval(spePatientEval);
if (!success)
{
return View(model);
}
return View("Index");
}
return View(model);
}

HTTP ERROR 404
What am I missing guys? I am sure it is something that is in plain site. I am just have looked at it too long and cannot find what is going on.
What have I tried... I feel like everything. I have tried adding a route to the HttpPost statement. I have tried making sure all the model fields are not null. I do not know what else to try.
Thanks in advance for any help.

Your POST route should match the GET route:
[HttpPost("[controller]/[action]/{IDAppt}/{ActivityID}/{VendorID}/{PatientID}")]

Add [FromRoute] to the action parameters:
[HttpGet("[controller]/[action]/{IDAppt}/{ActivityID}/{VendorID}/{PatientID}")]
public async Task<IActionResult> AddSPEPatientEval([FromRoute]int IDAppt, [FromRoute] int ActivityID, [FromRoute] int VendorID, [FromRoute] int PatientID)
You should also change HttpGet to HttpPost.

ASP.NET Core MVC - posting to a different action name does not bind the values

I'm using a regular html form instead of #html.BeginForm and I have these 2 form tags in my Create.cshtml view file.
I was experimenting with routing, but my post doesn't seem to get the values even if I bind the properties. I've tried in vain but I can't seem to make this work, and can't find the answer from googling.

The methods are getting hit but the post data is null.
Another question is, instead of using MVC convention, can I use a different method name for get and post that is not the same as the view name? How can I get initially load the page for GET using routing that would work in a different view name?
Thanks

can I use a different method name for get and post that is not the
same as the view name?
Yes, you can.
How can I get initially load the page for GET using routing that would
work in a different view name?
return to this view.
public IActionResult Create()
{
return View("aa");
}
Below is a work demo, you can refer to it.
In controller:
public IActionResult Create()
{
return View();
}
[HttpPost]
public IActionResult Create2(Actor actorItem)

ASP.NET MVC Razor DateTime Validation Error Message

So adjournHearingInfo's newHearingDate when I do not fill it in as the error message of
The value '' is invalid." with a value of "1/1/0001 12:00:00 AM"
I cannot figure out how to access this check its doing to change this error message. Or if that is not possible remove this check so I can validate the date myself and then generate the error message I want. Is this possible?
Currently I am able to add another error message to it, but I cannot remove that one.

Go to wwwroot\lib\jquery-validation\dist\additional-methods.js and find
$.validator.messages.date );
Try to delete either just the message or the whole line and see if it works.

The value is not set after POST if use asp-for attribute in MVC Core 3.1

I have simple view model:
public class GogViewModel
{
[Required]
public string Name { get; set; }
public bool IsBeta { get; set; }
public string Result { get; set; }
}
and controller:
[HttpGet]
public IActionResult Index()
{
return View(new GogViewModel());
}
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Index(GogViewModel model)
{
if (ModelState.IsValid)
{
model.Result = DoSomething();
}
return View(model);
}
and View:
#model GogViewModel
<div>
<form method="post">
#Html.AntiForgeryToken()
<div class="form-group row">
<label class="col-sm-2 col-form-label" asp-for="Name">Release name</label>
<div class="col-sm-10">
<input type="text" class="form-control" asp-for="Name" placeholder="paste release name here" />
</div>
</div>
<div class="form-group row">
<label class="col-sm-2 col-form-label" asp-for="Result">Result</label>
<div class="col-sm-9">
<input type="text" class="form-control-plaintext" readonly="readonly" asp-for="Result" />
<p>#Model.Result</p> <!-- it works here means the value is printed -->
</div>
<div class="col-sm-1">
<button type="button" class="btn btn-outline-info copy float-right" data-target="Result"><i class="far fa-copy"></i></button>
</div>
<div class="clearfix"></div>
</div>
<input type="submit" class="btn btn-success" value="Fix it" />
</form>
</div>
Somehow the result is not output after POST request.
Why ? Where's my mistake ?

It will work in the following way:
Set private setter to Result property => public string Result {get; private set;}
Add method which set value for Result: internal void SetResult(string result) { Result = result; }
In controller, call SetResult like: model.SetResult(...);
and will display in readonly input. I don't know why it works and I don't understand why the value is cleared when put it on input.
I used input with readonly attribute in order to copy to clipboard the output value with javascript.

maybe you need to add something in the input tag like value="#Model.Result"?

Why would a bool value not be displaying in view correctly?

I have a bool value that I'm using to distinguish between the first item in a series of other items being saved to a link table in my DB. The constructor for the ViewModel sets this to true by default. When my ViewModel is posted to the controller my controller action changes this value to false and passes the edited ViewModel back to the View where this value is saved in a hidden field.
The issue I have is that after the value has been changed, my View is still displaying this value as true. Does anyone have any idea where I'm going wrong?
I also have an issue where I reset the values back to default but these are being retained when the view is reloaded after the post action in executed.
