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);
}
This is all for the form AddSPEPatientEval.cshtml

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.

can't pass decimal value to model parameter

I have a Dto Like this
public class AgeDto
{
public long Id { get; set; }
[Required]
[Precision(2, 1)]
public decimal LowAge { get; set; }
[Precision(2, 1)]
public decimal? HighAge { get; set; }
}
and my for is like this
#model AgeDto
<form class="form-account" method="post" asp-action="Index" asp-controller="ages">
<div class="d-inline-block w-25">
<div class="label-form "> From</div>
<div>
<input asp-for="LowAge" type="text" class=" w-50">
<span asp-validation-for="LowAge" class="text-danger star-red"></span>
</div>
</div>
<div class="d-inline-block w-25">
<div class="label-form "> To</div>
<div>
<input asp-for="HighAge" type="text" class=" w-50">
<span asp-validation-for="HighAge" class="text-danger star-red"></span>
</div>
</div>
<div class="d-inline-block w-25">
<div class="d-inline-block px-3">
<input asp-for="Id" type="hidden" />
<input class="btn btn-primary btn-register" type="submit" value="Register" />
</div>
</div>
</form>
and controller like this
[HttpPost]
public async Task<IActionResult> Index(AgeDto agesDto)
{
// does something
}
althought the LowAge and HighAge are decimal, but if enter 1.5 or 2.5 or any number with fractional it passes value 0 on agesDto on Controller
why is that so?

0 is the default value for your model properties. It's most likely the modelbinding doesnt recognize any valid values to apply to the properties.
Most of the time this is due to culture conflicts for the separator, especially since you're using text-inputs for the properties.

Blazor data annotations error messages in a tooltip

I have a blazor webassembly application. I added data annotations to my code and data validations are now displayed on top of page.
Now I have a requirement to display the validations error messages in submit tooltip.
Can anyone please help me how to show validations msgs in submit button tooltip.
Below is my code.
<EditForm Model="_product" OnValidSubmit="Submit" style="width:600px;">
<DataAnnotationsValidator />
<ValidationSummary />
<div class="form-group row">
<label for="name" class="col-md-2 col-form-label">Name:</label>
<div class="col-md-10">
<InputText id="name" class="form-control" #bind-Value="_product.Name" />
</div>
</div>
<div class="form-group row">
<label for="supplier" class="col-md-2 col-form-label">Supplier:</label>
<div class="col-md-10">
<InputText id="supplier" class="form-control" #bind-Value="_product.Supplier"/>
</div>
</div>
<div class="row">
<div class="col-md-12 text-right">
<button type="submit" class="btn btn-success" data-bs-toggle="tooltip" data-bs-placement="left" title="errorMessages">
Submit
</button>
</div>
</div>
</EditForm>
#code {
private string errorMessages = string.Empty;
private Product _product = new() {};
protected override async Task OnInitializedAsync()
{
await InvokeAsync(StateHasChanged);
}
private void Submit(){
Console.WriteLine("Submitted");
}
}
Below is code for Model
public class Product
{
[Required]
public string Name { get; set; }
[Required]
[SupplierValidation(ErrorMessage = "Wrong value entered", ValidSupplierValue = "Code-Maze")]
public string Supplier { get; set; }
}

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)
{
return View();
}
Create view:

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.
