I made an action to delete and delete, but in View delete does not appear the value of the field, which comes from the model. This is cshtml:

@model TreinamentoCrud.Models.Cidade

@{
    ViewBag.Title = "Delete";
}

<h2>Delete</h2>

<h3>Are you sure you want to delete this?</h3>
<div>
    <h4>Cidade</h4>
    <hr />
    <dl class="dl-horizontal">
        <dt>
            @Html.DisplayNameFor(model => model.nome)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.nome)
        </dd>

    </dl>

    @using (Html.BeginForm()) {
        @Html.AntiForgeryToken()

        <div class="form-actions no-color">
            <input type="submit" value="Delete" class="btn btn-default" /> |
            @Html.ActionLink("Voltar", "Index")
        </div>
    }
</div>

and this is the controller

public async Task<ActionResult> Delete(int id)
        {
            DeleteCidadeAsync deleteCidade = new DeleteCidadeAsync();

            await deleteCidade.DeleteCidade(id);

            return View();
        }

However delete, the attribute in the method is like [HttpPost] . Is this normal? See in this screenshot what I am saying

            }
            catch
            {
                return View();
            }
        }

My method is like this now

public class DeleteCidadeAsync
    {
        HttpClient client = new HttpClient();

        public async Task DeleteCidade(int id, Cidade cidade)
        {
            string url = $"http://localhost:56137/api/DeleteCidade/{id}";
            await client.DeleteAsync(url);
        }
    }

See that way and the previous one, both are deleting. It just does not show the name of the face to be deleted.

AJAX updating the wrong table My url does not get the id parameter in the show? id =. Because?

Well, you're deleting the city already, and if you want to show some data for that city, you need to have two Delete methods, a GET (to display city information), and a POST (to confirm the deletion):

    [HttpGet]
    public async Task<ActionResult> Delete(int id)
    {
        SuaClasseDeBuscarCidadesbusca = new SuaClasseDeBuscarCidades();

        Cidade cidade = busca.SeuMetodoQueBuscaCidade(id);

        return View(cidade);
    }

    [HttpPost]
    [ActionName("Delete")]
    public async Task<ActionResult> ConfirmDelete(int id)
    {
        DeleteCidadeAsync deleteCidade = new DeleteCidadeAsync();

        await deleteCidade.DeleteCidade(id);

        return RedirectToView("Index");
    }

The post method should be called by clicking the Delete button, which confirms the removal of the city.
