ASP MVC: Sending an E-mail and return Message (No Json)

Question

I have a doubt have a project done in ASP.NET MVC 3, where there is a contact form. It works perfectly the problem is that I want to put a message "Email Sent successfully!" to complete your submission. I'm not using Json. What would be the most appropriate solution Thank you!

the code:

Contato.cshtml `

@model SSInstitucional.ViewModel.ContatoViewModel
 @using System.Web     

<link href="../../Content/themes/SCTecno.css" rel="stylesheet" type="text/css" />

@using (Html.BeginForm("EnviaEmail")) 
{
    @Html.ValidationSummary(true, "")

    <div id ="divContato" style="text-align:left;  margin-left:460px; margin-right:400px; font-family:Verdana;">

            <div id="txtNome" class="editor-label">
                @Html.LabelFor(model => model.Nome)
               <p>
                @Html.TextBoxFor(m => m.Nome, new { id = "Nome", size = 40, maxlength = "60" })
                @Html.ValidationMessageFor(model => model.Nome)
            </div>
            <div id="txtEmail" class="editor-field">
                @Html.LabelFor(model => model.Email)
                <p>
                @Html.TextBoxFor(m => m.Email, new { id = "Email", size = 40, maxlength = "200" })
                @Html.ValidationMessageFor(model => model.Email)
            </div>
            <div  id="txtAssunto"class="editor-label">
               @Html.LabelFor(model => model.Assunto)
                <p>
                @Html.TextBoxFor(m => m.Assunto, new { id = "assunto", size = 40, maxlength = "200" })
                @Html.ValidationMessageFor(model => model.Assunto)
            </div>
            <div id="txtMensagem" class="editor-field">
               @Html.LabelFor(model => model.Mensagem)
               <p>
                @Html.TextAreaFor(model => model.Mensagem, new { id = "mensagem", rows = "10", cols = "50", maxlength = "5000" })
                @Html.ValidationMessageFor(model => model.Mensagem)
            </div>

                <div id="Enviar" onClick="alert('E-mail enviado com sucesso!!')")>
             @SSHtml.SubmitStyledButton("Enviar")
                </div>





   </div>

If you can use js, you could use a MVC Ajax form. A example is here http://www.hanselman.com/blog/ASPNETMVCPreview4UsingAjaxAndAjaxForm.aspx

You just need replace

@using (Html.BeginForm("EnviaEmail")) 
{
   ....
}

with

@using(Ajax.BeginForm("EnviaEmail", new AjaxOptions
                                                      {
                                                              UpdateTargetId = "form_wrapper_id",
                                                              InsertionMode = InsertionMode.Replace
                                                      }))
{
    ...
}

and return from Action some massage. This message will be put to HTML tag with id 'form_wrapper_id'. If you can't use js the answer by Darin Dimitrov is the best.

Your form is currently pointing to the EnviaEmail controller action. The EnviaEmail controller action doesn't do anything. It only redisplays the view. It doesn't send any email whatsoever. So I guess that your original code is actually pointing to the Index POST action:

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

From what I can see in your code this POST action sends an email and redisplays the same view. So once the email is sent you could store some message in the ViewBag:

[HttpPost]
public ActionResult Index(ContatoViewModel contatoViewModel)
{
    string corpo = "Nome: " + contatoViewModel.Nome + "\n" +
                       "E-Mail: " + contatoViewModel.Email + "\n" +
                       "Assunto: " + contatoViewModel.Assunto + "\n\n" +
                       contatoViewModel.Mensagem;

    sendEmail(contatoViewModel.Nome, contatoViewModel.Email, contatoViewModel.Assunto, corpo);

    ViewBag.Message = "Email sent successfully";
    return View();
}

and then in your view display this message:

<div>@ViewBag.Message</div>
