ModelState.IsValid is false during my post - asp.net-mvc

Question

This is my controller:
[HttpPost]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult EMail(SendMailData objModelMail, HttpPostedFileBase fileUploader,SendMailData smd)
{
//string Emailid = smd.To;
//TryUpdateModel<SendMailData>(smd);
//var result = new List<ValidationResult>();
//var Context = new ValidationContext(ModelState, null, null);
//var errors = ModelState.Where(v => v.Value.Errors.Any());
if (ModelState.IsValid)
{
string from = "MYMAILID";
using (MailMessage mail = new MailMessage(from, objModelMail.To))
{
mail.Subject = objModelMail.Subject;
mail.Body = objModelMail.Body;
if (fileUploader != null)
{
string Filename = Path.GetFileName(fileUploader.FileName);
mail.Attachments.Add(new Attachment(fileUploader.InputStream, Filename));
}
//mail.To.Add(new MailAddress(eMailBox.Text));
// mail.To.Add(objModelMail.To);
//mail.From = new MailAddress(objModelMail.From);
//mail.Subject = objModelMail.Subject;
//string body = objModelMail.Body;
//mail.Body = body;
mail.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient("127.0.0.1", 25);
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("MYMAILID", "PASSWORD",from);
smtp.Port = 587;
smtp.ServicePoint.MaxIdleTime = 1;
smtp.Host = "smtp.gmail.com";
smtp.Send(mail);
ViewBag.message = "Send";
mail.Dispose();
return View("EMail", objModelMail);
}
}
else
{
return View();
}
}
This is my model:
public class SendMailData
{
[Required(ErrorMessage = "You Can't Leave This Empty")]
[RegularExpression(#"^(([a-zA-Z0-9_'+*$%\^&!\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9:]{2,7})([,;]\W?(?!$))?)+$", ErrorMessage = "Please enter correct email address")]
public string To { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
}
This is my View:
#model SampleUniversity1.Models.SendMailData
#{
ViewBag.Title = "EMail";
}
<script src="~/Scripts/jquery-1.7.1.min.js">
</script>
<script type="text/javascript">
if ('#ViewBag.message' == 'Send') {
alert("Email Sended Successfully");
}
</script>
<h2>Mail</h2>
<fieldset>
<legend>
Send Mail
</legend>
#using (Html.BeginForm("EMail", "Student", FormMethod.Post, new { #id = "form1", #enctype = "multipart/form-data" }))
{
#*#Html.AntiForgeryToken();*#
#Html.ValidationSummary(true)
<input type="submit" value="Send" style="width: 100px;" />
<table>
<tr>
<td>
To
</td>
<td>
#Html.TextAreaFor(x => x.To)
#Html.ValidationMessageFor(x => x.To)
</td>
</tr>
<tr>
<td>
Subject
</td>
<td>
#Html.TextAreaFor(x => x.Subject)
</td>
</tr>
<tr>
<td>
Attachment
</td>
<td>
<input type="file" name="fileUploader" />
</td>
</tr>
<tr>
<td>
Body
</td>
<td>
#Html.TextAreaFor(x => x.Body)
</td>
</tr>
<tr>
<td></td>
</tr>
</table>
}
</fieldset>
When I enter all the values correct it will display no error only else part is processing
else part is execute ModelState.IsValid is false.

Answer 1

You have a RequiredAttribute on the From property, but I can't see any input for it in you view, so it will be null and ModelState.IsValid() will be false
