Why is asp-route-id not working in my form post?
Solution 1
You must change the asp-route-id
to asp-route-Id
because after "asp-router-
" you must put the name of the parameter that you are going to send to the method.
Solution 2
I inspected the form tag in response to junnas' comments.
It looked like this:
<form method="post" action="/Account/Delete/5066a97b-7eb4-4e1d-889b-3f3450adc1d6">
<button type="submit" class="btn btn-primary" formaction="/Account/Delete">Yes - Delete this User</button>
<a class="btn btn-default" href="/Account">Cancel</a>
<input name="__RequestVerificationToken" type="hidden" value="CfDJ8At6yzynfgJHstUkF5jJTYgHHX0on9ajBa9NfD60YGbM7aRhKjDQUGkh4gPAMkwwOsnqUtDxSx87MnUvbxcefB7tGX1v0Xi38h_SoL_iakiFdJSpUbymp4tsr-cMFNK3kwYx7o42OumLkFbvFn1Nyun_8LDc0mmOvGN5LeeHiIq84cSJCaaiyR_2talw6Dpcvw" /></form>
Notice the extra formaction="/Account/Delete"> right on the button in addition to the form action.
I had an extra asp-route-id left over on a button I had changed over from an anchor.
I had to take it off the button here:
<form asp-controller="Account" asp-action="Delete" asp-route-id="@Model.Id" method="post">
<button asp-route-id="@Model.Id" type="submit" class="btn btn-primary">Yes - Delete this User</button>
<a asp-action="Index" class="btn btn-default">Cancel</a>
</form>
and make the button like this:
Yes - Delete this User

I have asp-route-id working in one instance:
It works from an anchor tag like this:
<a id="editModal" data-toggle="modal" data-target="#modal_box" class="btn btn-sm btn-primary" asp-action="Edit" asp-route-id="@user.Id">Edit</a>
and is received like this:
public async Task<PartialViewResult> DeleteConfirm(string Id) => PartialView("_DeleteConfirm", await _userManager.FindByIdAsync(Id));
This method receives the correct id.
The next example has the route id in the form tag like this:
<div class="modal-footer"> <form asp-controller="Account" asp-action="Delete" asp-route-id="@Model.Id" method="post"> <button type="submit" class="btn btn-primary" asp-action="Delete">Yes - Delete this User</button> <a asp-action="Index" class="btn btn-default">Cancel</a> </form> </div>
and I am trying to receive the Id here:
[HttpPost] public async Task<IActionResult> Delete(string Id) { AppUser user = await _userManager.FindByIdAsync(Id); if (user != null) { IdentityResult result = await _userManager.DeleteAsync(user); if (result.Succeeded) { return RedirectToAction("Index"); } else { AddErrorsFromResult(result); } } else { ModelState.AddModelError("", "User Not Found"); } return View("Index", _userManager.Users); }
But in this case the parameter is coming in null.
It should work from the from tag. I got this from the first Identity Chapter in Adam Freemans APress MVC Core book and it worked when I typed it in for that example.
