I need to do a routine to send email, through a form I made, using the VS2015 SPA Template. I put two buttons, Cancel and Send. The question is not in the email code, but how to assign the Click of the button to my code in the Controller and also the fields. I am using SPA for learning, so I used the VS2015 template and I modified it as needed.

This is inha View (CSHTML)

@model Projeto.Models.ContactEmail
@using (Html.BeginForm("Email", "Email", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
    @Html.AntiForgeryToken()
    <h4>Enviar email.</h4>
    <hr />

    @Html.ValidationSummary("", new { @class = "text-danger" })
    <div class="form-group">
        @Html.LabelFor(m => m.Nome, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Nome, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.Assunto, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Assunto, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.Texto, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextAreaFor(m => m.Texto, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" class="btn btn-danger" value="Cancelar" />
            <input type="submit" class="btn btn-success" value="Enviar" />
        </div>
    </div>
}

Here is the Controller code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;

namespace Projeto.Controllers
{
    public class EmailController : Controller
    {
        // GET: Email
        public ActionResult Email()
        {
            return View();
        }

        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> EnviarEmail()
        {
            //Aqui deve ir o código de tudo, enviar email e etc
            return View(model);
        }
    }
}

This is the Email template:

public class ContactEmail
    {
        [Required]
        [Display(Name = "Nome")]
        public string Nome { get; set; }

        [Required]
        [Display(Name = "Email")]
        public string Email { get; set; }

        [Required]
        [Display(Name = "Assunto")]
        public string Assunto { get; set; }

        [Required]
        [Display(Name = "Texto")]
        public string Texto { get; set; }
    }

This is my email routine:

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public ActionResult EnviarEmail(ContactEmail contactEmail)
        {
            WebMail.SmtpServer = "mail19.redehost.com.br";
            WebMail.SmtpPort = 587;
            //WebMail.EnableSsl = true;
            WebMail.From = contactEmail;
            WebMail.UserName = "[email protected]";
            WebMail.Password = "tested123";
            WebMail.Send(contactEmail.Email, contactEmail.Assunto, contactEmail.Texto);

            return View(contactEmail);
        }

Where contactEmail is the email entered on the page by the users of the same. [email protected] - > This is where I'm sending the email. I already changed (Inverti) and it continues without sending. With the above configuration, I get this error:

c# single-page-application asp.net-mvc visual-studio-2015

See that you have your entire form in View within:

@using (Html.BeginForm("Email", "Email", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
    //Seu form
}

So you can do this on your Controller to check if Submit is running:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> EnviarEmail()
{
    if (Request.Form["Submit"] != null)
    {
        if (Request.Form["Submit"].ToString() == "Enviar")
        {
            //Aqui deve ir o código de tudo, enviar email e etc
        }
        else
        {
            //Outro tratamento
        }
    return View(model);
}

You can also use a named argument:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> EnviarEmail(string submit)
    {
        switch (submit)
        {
            case "Enviar":
               ...
            case "Cancelar":
               ...
            default:
               ...
        }

        //Aqui deve ir o código de tudo, enviar email e etc
        return View(model);
    }

Just make sure that each button has the name attribute:

        <input name="submit" type="submit" class="btn btn-danger" value="Cancelar" />
        <input name="submit" type="submit" class="btn btn-success" value="Enviar" />

If you just want to clear the form, I do not see the need to make a POST for this. You can just refresh the page or "reset" form would solve your problem.

To refresh the page, you can do something like this on your cancel button:

<a href="@Url.Action("Email", "Email")" class="btn btn-danger"> Cancelar</a>

If you just want to clear the fields, you can reset form . An example would be to change your cancel button to this:

<input type="button" class="btn btn-danger" value="Cancelar" onclick="this.form.reset();"/>

See an example in .NetFiddle

I would like to look at a possible problem, in your Html.BeginForm you defined Action as Email :

@using (Html.BeginForm("Email", "Email", ...

But in your Controller you call Action EnviarEmail :

public async Task<ActionResult> EnviarEmail()

So I assume the correct one would be to cancel:

 <a href="@Url.Action("EnviarEmail", "Email")" class="btn btn-danger"> Cancelar</a>

And the correct form would be:

@using (Html.BeginForm("EnviarEmail", "Email", ...
