What to return when posting a form from a partial view

I am new to MVC and am trying to implement a contact page.
I created a partial view for the contact part and I am adding it on my index page with this line
#Html.Partial("_Contact")
When my form is submitted my code executes and when the form is not valid I have to return something.
My question is what do I have to return to make it work.
I want to return my model to my contact partial view but I still have to show my index page because the contact part is shown there.
Or am I looking at it the wrong way?
This is the post code:
[ValidateAntiForgeryToken]
public IActionResult _Contact(EmailFormModel model)
{
if (ModelState.IsValid)
{
var path = _hostingEnvironment.WebRootPath;
string html = System.IO.File.ReadAllText(path);
var message = new MailMessage();
var templatePath = path + _configuration.GetSection("Email.PathToHtmlTemplate").Value;
var smtpHost = _configuration.GetSection("Email.Smtp.Host").Value;
var smtpPort = Convert.ToInt32(_configuration.GetSection("Email.Smtp.Port").Value);
var smtpUser = _configuration.GetSection("Email.Smtp.UserName").Value;
var smtpPass = _configuration.GetSection("Email.Smtp.Password").Value;
var from = _configuration.GetSection("Email.From").Value;
var to = _configuration.GetSection("Email.To").Value;
var cc = _configuration.GetSection("Email.Cc").Value;
var bcc = _configuration.GetSection("Email.Bcc").Value;
var subject = _configuration.GetSection("Email.Subject").Value;
var dic = new Dictionary<string, string>()
{
{ "{{NAME}}", model.Name },
{ "{{TEL}}", model.Telephone },
{ "{{EMAIL}}", model.Email },
{ "{{MESSAGE}}", model.Message },
};
dic.ForEach(x => html = html.Replace(x.Key, x.Value));
foreach (var t in to.Split(';'))
{
message.To.Add(new MailAddress(t));
}
foreach (var t in cc.Split(';'))
{
message.CC.Add(new MailAddress(t));
}
foreach (var t in bcc.Split(';'))
{
message.Bcc.Add(new MailAddress(t));
}
message.From = new MailAddress(from);
message.Subject = subject;
message.Body = html;
message.IsBodyHtml = true;
using (var smtp = new SmtpClient())
{
var credential = new NetworkCredential
{
UserName = smtpUser,
Password = smtpPass
};
smtp.Credentials = credential;
smtp.Host = smtpHost;
smtp.Port = smtpPort;
smtp.Send(message);
return View("EmailSent");
}
}
return View(model);
}
The index view:
#{
ViewData["Title"] = "Home Page";
}
...
#Html.Partial("_Contact")
The contact view:
#model EmailFormModel;
#{
ViewData["Title"] = "Contact";
}

how to print the elements with text value that contains in a list selenium c#

Anyone know how to print out all the elements that contain in a list with text value in selenium c#? Try to do like the code below it print out blank value. But if i were to put writeline with elem only the value was display but it is not in text form. I would like to get value with text.
Code:
IList<IWebElement> attachmentList = driver.FindElements(By.ClassName("comment-box"));
foreach (IWebElement element in attachmentList)
{
Console.WriteLine(element.Text);
}
HTML:
<div class="comment-box">
<!-- Comment Image -->
<div class="col-xs-2">
<div id="attachmentImgSFHD-24" class="attachmentImg">
<img src="downloadAttachment?attachmenturl=/secure/thumbnail/10111/_thumb_10111.png" />
</div>
</div>
<!-- Attachment details -->
<div class="col-xs-10">
<div class="commentContent">
<div class="topRow">
<div class="username">ApplicationLink.png</div>
<div class="commentTimeStamp">31400 KB</div>
</div>
<div class="bottomRow">
<div class="commentDisplay">
Download
</div>
</div>
</div>
</div>
</div>
<div class="comment-box">
<!-- Comment Image -->
<div class="col-xs-2">
<div id="attachmentImgSFHD-24" class="attachmentImg">
<img src="downloadAttachment?attachmenturl=/secure/thumbnail/10313/_thumb_10313.png" />
</div>
</div>
<!-- Attachment details -->
<div class="col-xs-10">
<div class="commentContent">
<div class="topRow">
<div class="username">test.jpg</div>
<div class="commentTimeStamp">7423 KB</div>
</div>
<div class="bottomRow">
<div class="commentDisplay">
Download
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<br/>

The elements don't have text in the html, so element.Text is empty. Use
Console.WriteLine(element.GetAttribute("value"));

You can use the below Xpath to get the attachment details
Xpath: //div[#class='comment-box']//div[#class='commentContent']//div[#class='username']
Code:
IList<IWebElement> attachmentList = driver.FindElements(By.XPath("//div[#class='comment-box']//div[#class='commentContent']//div[#class='username']"));
foreach (IWebElement element in attachmentList)
{
Console.WriteLine(element.Text);//It will print all the attachment name like 'ApplicationLink.png,test.jpg'
}

IList<IWebElement> attachmentList = driver.FindElements(By.ClassName("comment-box"));
foreach (IWebElement element in attachmentList)
{
System.Threading.Thread.Sleep(2000);
Console.WriteLine(element.Text);
}
it works fine by putting the thread.sleep code

asp.net c# sort right product under right category

I'm trying to render out my projects sorted under the right category. I have it right now so right product will go under right category but it doesn't render out the name. It renders out the object so it looks rather weird.
This is my code:
int i = 0;
var categories = ViewBag.Category as List<Category>;
var products = ViewBag.Products as List<Product>;
foreach (var cateory in categories)
{
i++;
<div class="panel-group accordion" id="accordion1">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion1" href="#collapse_#i">
#cateory.Name
</a>
</h4>
</div>
<div id="collapse_#i" class="panel-collapse collapse">
<div class="panel-body">
<div class="col-md-12">
#cateory.Products
</div>
</div>
</div>
</div>
</div>
}
And this is the output.
System.Collections.Generic.HashSet`1[ProductCatalog.Models.Product]
I have tired this #cateory.Products.Select(n => n.Name).ToString(); but did not do much.

cshtml c# There is already an open DataReader associated with this Connection which must be closed first

Im making PostHelper.cshtml in App_Code folder inside my Blog project. And I got this error on line:
<div class="commentsTab">
#Post.comments.Count**
</div>
and:
#foreach (tag Tag in **Post.tags**)
when Im deleting "#Post.comments.Count" its fine but Ive got similar line and there's no errors:
<div class="postTitle">#Post.Title</div>
whats wrong with this? There's whole code:
#using Blog.Models;
#helper Render(post Post, System.Web.Mvc.HtmlHelper html, bool isAdmin, bool showComments)
{
<div class="postTitle">#Post.Title</div>
<div class="postContainer">
<div class="postTabs">
<div class="dateTab">
<div class="month">#Post.DateTime.ToString("MMM").ToUpper()</div>
<div class="day">#Post.DateTime.ToString("dd")</div>
</div>
<div class="commentsTab">
#Post.comments.Count
</div>
</div>
<div class="postContent">
<div class="postBody">#html.Raw(Post.Body)</div>
<div class="tagList">
#foreach (tag Tag in Post.tags)
{

#foreach (comment Comment in Post.comments.OrderBy(x => x.DateTime))
{

}
}
My action:
public ActionResult Index(int? id)
{
int pageNumber = id ?? 0;
IEnumerable<post> posts =
(from Post in model.posts
where Post.DateTime < DateTime.Now
orderby Post.DateTime descending
select Post).Skip(pageNumber * PostsPerPage).Take(PostsPerPage + 1);
ViewBag.IsPreviousLinkVisible = pageNumber > 0;
ViewBag.IsNextLinkVisible = posts.Count() > PostsPerPage;
ViewBag.PageNumber = pageNumber;
ViewBag.IsAdmin = IsAdmin;
return View(posts.Take(PostsPerPage));
}

I presume your exception is caused by an already open connection to the DB that you are not closing. In your case try to add a .ToList at the end of your initial select:
select Post).Skip(pageNumber * PostsPerPage).Take(PostsPerPage + 1).ToList();
This will close the reader and copy all results in your memory. See if that makes any difference.

You need MARS. Add: MultipleActiveResultSets=True; to your connection string. See: http://msdn.microsoft.com/en-us/library/ms131686.aspx

Html Agility Pack SelectSingleNode giving always same result in iteration?

I would like the nodes in the collection but with iterating SelectSingleNode I keep getting the same object just node.Id is changing...
What i try is to readout the webresponse of a given site and catch some information like values, links .. in special defined elements.
int offSet = 0;
string address = "http://www.testsite.de/ergebnisliste.html?offset=" + offSet;
HtmlWeb web = new HtmlWeb();
//web.OverrideEncoding = Encoding.UTF8;
HtmlDocument doc = web.Load(address);
HtmlNodeCollection collection = doc.DocumentNode.SelectNodes("//div[#itemtype='http://schema.org/Posting']");
foreach (HtmlNode node in collection) {
string id = HttpUtility.HtmlDecode(node.Id);
string cpname = HttpUtility.HtmlDecode(node.SelectSingleNode("//span[#itemprop='name']").InnerText);
string cptitle = HttpUtility.HtmlDecode(node.SelectSingleNode("//span[#itemprop='title']").InnerText);
string cpaddress = HttpUtility.HtmlDecode(node.SelectSingleNode("//span[#itemprop='addressLocality']").InnerText);
string date = HttpUtility.HtmlDecode(node.SelectSingleNode("//div[#itemprop='datePosted']").InnerText);
string link = "http://www.testsite.de" + HttpUtility.HtmlDecode(node.SelectSingleNode("//div[#class='h3 title']//a[#href]").GetAttributeValue("href", "default"));
}
This is for example for 1 iteration:
<div id="66666" itemtype="http://schema.org/Posting">
<div>
<a>
<img />
</a>
</div>
<div>
<div class="h3 title">
<a href="/test.html" title="Test">
<span itemprop="title">Test</span>
</a>
</div>
<div>
<span itemprop="name">TestName</span>
</div>
</div>
<div>
<div>
<div>
<div>
<span itemprop="address">Test</span>
</div>
<span>
<a>
<span><!-- --></span>
<span></span>
</a>
</span>
</div>
</div>
<div itemprop="date">
<time datetime="2013-03-01">01.03.13</time>
</div>
</div>

By writing
node.SelectSingleNode("//span[#itemprop='name']").InnerText
it's like you writing
doc.DocumentNode.SelectSingleNode("//span[#itemprop='name']").InnerText
To do what you want to do you should write it like this: node.SelectSingleNode(".//span[#itemprop='name']").InnerText.
This .dot / period tells make a search on the current node which is node instead on doc
