Cannot add class to aspx.cs file

I have 2 files in my web site project, Translator2.aspx and Translator2.aspx.cs. I want to add new class (Erwin:Translator2) to my Translator2.aspx.cs file. However it was error like this :
Severity Code Description Project File Line Suppression State
Error 'translator2_aspx' does not contain a definition for 'Switch'
and no extension method 'Switch' accepting a first argument of type
'translator2_aspx' could be found (are you missing a using directive
or an assembly reference?)

string str2 = testing1.Text;
System.Console.WriteLine("Inside Main, before swapping: {0} {1}", str1, str2);

}
}
Do you have any idea why I can't add Erwin:Translato2 class? everything works fine before I add the class. Did I miss something?

The Switch method is in a different class than the class that is powering your aspx page. If you want switch to be some kind of utility method, you should create a new class, maybe Erwin in a completely separate file (Erwin.cs), and have a switch method inside that that is public and probably static. I also note that switch doesn't return anything, so not sure what you are trying to accomplish with it.
The OnClick handler for your button should be in the code behind -- ie in the Translator2 class. Inside this handler, you could call Erwin.Switch().

ASP.NET TextBox won't add text from C#

I am trying to do a multi Client - Server application. After I did some of the basic controls and functions with Windows Forms I thought to add a WebPage to my Client side.
I created a new project and edited it and it works ok, the page is connecting to the server and it receives the messages I send from the web page.
The problem I get when I need to post messages on a textbox on the web page. I searched on some pages here, on the internet and I can't find a good solution for my problem. I alose used the Page.IsPostBack but it didn't work, then I added an UpdatePanel because the page was refreshing when I clicked the buttons but that didn't work either... Now I am out of ideas.
Can anybody suggest how should I do this ? My code behind is C# and I don't know how to parse these details to JavaScript or jQuery, so any of you have some details on how to that it will also be appreciated.
Thanks in advance.
And also I will post anything needed if there is important for this question.
EDIT (Added code):
public void btnSend_Click(object sender, EventArgs e)
{
if (tbSendMessage.Text.Length > 0)
{
string message = tbSendMessage.Text;
byte[] outStream = Encoding.ASCII.GetBytes(message + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
tbSendMessage.Text = string.Empty;
}
}
private void getMessage()
{
while (true)
{
try
{
serverStream = clientSocket.GetStream();
int buffSize = 0;
byte[] inStream = new byte[70000];
buffSize = clientSocket.ReceiveBufferSize;
serverStream.Read(inStream, 0, buffSize);
string returndata = Encoding.ASCII.GetString(inStream);
//tbReceivedMessages.Text += returndata + "\n";
ShowMessage(returndata);
}
catch (Exception ex)
{
ShowAlert("Connection lost.\n" + ex.Message);
//ShowMessage("Conexiunea cu serverul s-a pierdut.\n" );
serverStream.Close();
return;
}
}
}
private void ShowMessage(string message)
{
sb.AppendLine(message);
tbReceivedMessages.Text += sb;
}
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">

If you want two server controls to communicate each other via Ajax, you will need to place them in same UpdatePanel.
FYI: If you are new to ASP.Net Web Form, do not use UpdatePanel yet. Instead, make it work with regular post back.
<asp:UpdatePanel ID="UpdatePanelConnect" runat="server">

</asp:UpdatePanel>
public void btnSend_Click(object sender, EventArgs e)
{
if (tbSendMessage.Text.Length > 0)
{
string message = tbSendMessage.Text;
// This code won't work.
/*byte[] outStream = Encoding.ASCII.GetBytes(message + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
tbSendMessage.Text = string.Empty;*/
}
}

Why is my smtp SendMail prohibiting Log in fuctions, on site master?

I'm working in asp.net with c# and I decided to build a pop-up messaging module. I have done this on previous projects; however, I've never used it on a site that was also utilizing the Identity Framework or placed in my master page. I am also fairly new to C#.
The messenger appears to be working fine. However, now any kind of "submit" or "send" function found on the master page will not work properly. For example, if I try to log in as an admin, I will get my windows error messages for the field validation on the messenger. I tried taking out the RequiredFieldValidators, I was still unable to log in, instead it tried to send a message.
I then tried moving the module into a usercontrol and running it that way, still no luck. I had considered building a new masterpage for the log in page, that way I could remove the "contact" from the navigation on that page, thus eliminating the issue . However, I would prefer not to have to do this. I am sure there is a simple solution to correcting this, and my lack of experience with c# is not helping much.
Here is part of the navigation on my Site.Master, just to give an idea about what I'm doing:
<li><a runat="server" href="#" data-toggle="modal" data-target=".pop-up-1">Contact</a></li>
</ul>
<asp:LoginView runat="server" ViewStateMode="Disabled">
<AnonymousTemplate>
<ul class="nav navbar-nav navbar-right">
<li><a runat="server" href="~/Account/Login" style="color:#f46de6">Admin</a></li>
<li><asp:HyperLink ID="PayPalViewCart" runat="server" NavigateUrl=<%# Link.ToPayPalViewCart() %> style="color:#f46de6">View Cart</asp:HyperLink></li>
</ul>
</AnonymousTemplate>
<LoggedInTemplate>
<ul class="nav navbar-nav navbar-right">
<li><a runat="server" href="~/Account/Manage" title="Manage your account" style="color:#f46de6" >Hello, Admin</a></li>
<li>
<asp:LoginStatus runat="server" LogoutAction="Redirect" LogoutText="Log off" LogoutPageUrl="~/" OnLoggingOut="Unnamed_LoggingOut" />
</li>
</ul>
</LoggedInTemplate>
</asp:LoginView>
</div>
</div>
</div>
<uc1:popup1 runat="server" id="popup1" />
<div class="container body-content">
Now here is the code behind on this page, site.Master.cs:
public partial class SiteMaster : MasterPage
{
private const string AntiXsrfTokenKey = "__AntiXsrfToken";
private const string AntiXsrfUserNameKey = "__AntiXsrfUserName";

mail.To.Add("");
mail.Subject = "Information Request";
mail.IsBodyHtml = true;
mail.Body = "Name:" + this.txtName.Text + "<br />";
mail.Body += "Organization:" + txtOrganization.Text + "<br />";
mail.Body += "Phone:" + txtPhone.Text + "<br />";

//Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;

if (!cs.IsClientScriptBlockRegistered(csType, csName))
{

Send information stored in a repeater to email recipient?

I would like to take all information stored in a repeater and place it in the body of an email message for sending. Basically, it's a product order form (which also makes use of a repeater) that sends users to an order review page with a form at the bottom that allows them to send the order information to someone else. I am allowed to set up the order information as a table. I have everything working, and my code successfully sends emails. However, I am not sure how to pull the order review repeater's contents into the message body for an email.
Any suggestions/tips are appreciated! Thanks!

I think this answer has what you're looking for. Basically, you can use javascript to send the html to the server in order to include it in your email:
asp.net get html controls in code behind
Also, make sure you include a ValidateRequest="false" on the page in order to post back html

if someone else has same problem and the repeater object has no image this solution is simple and easy instead of trust to a client javascript feedback !!
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =new HtmlTextWriter(stringWrite);
Repeater1.RenderControl(htmlWrite);string emailContent = stringWrite.ToString();

Sending an email once a form is submitted using smtp and gmail in asp.net

I'm trying to receive an email once my form is submitted on my webpage. At the moment it submits fine without any errors but I don't receive the email. Does anyone know what code I have to add in the code behind page to make this work?
Here is the html;
<h2>Contact Us</h2>
<br />
<table>
<tr>
<td style="align-items:center">
Name:</td>
<td>
<asp:TextBox ID="txtName"
runat="server"
Columns="40"></asp:TextBox>
</td>
</tr>
<tr>
<td style="align-items:center">
email:</td>
<td>
<asp:TextBox ID="txtEmail"
runat="server"
Columns="40"></asp:TextBox>
</td>
</tr>
<!-- Message -->
<tr>
<td style="align-items:center">
What are you looking for?
</td>
<td>
<asp:TextBox ID="txtMessage"
runat="server"
Columns="40"
Rows="6"
TextMode="MultiLine"></asp:TextBox>
</td>
</tr>
<tr>
<td style="align-items:center">
What would you be willing to pay for this app?</td>
<td>
<asp:TextBox ID="txtPay"
runat="server"
Columns="40"></asp:TextBox>
</td>
</tr>
<!-- Submit -->
<tr style="align-items:center">
<td colspan="2">
<asp:Button ID="btnSubmit" runat="server" Text="Submit"
onclick="btnSubmit_Click" /><br />
</td>
</tr>
<!-- Results -->
<tr style="align-items:center">
<td colspan="2">
<asp:Label ID="lblResult" runat="server"></asp:Label>
</td>
</tr>
</table>
this is the code behind;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Mail;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Telluswhatyouwant : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
try
{
//Create the msg object to be sent
MailMessage msg = new MailMessage();
//Add your email address to the recipients
msg.To.Add("ronan.byrne#mhlabs.net");
//Send the msg
client.Send(msg);

This is a perfectly working code for localhost where mailing option is enabled. You can change the port number.fromWho, toWho are mailing addresses in string format (ie: david#yahoo.com)
string sMailServer = "127.0.0.1";
MailMessage MyMail = new MailMessage();
MyMail.From = fromWho;
MyMail.To = toWho;
if (toCC != "" || toCC != null)
{
MyMail.Cc = toCC;
}
if (toBCC != "" || toBCC != null)
{
MyMail.Bcc = toBCC;
}
MyMail.Subject = Subject;
MyMail.Body = Body;
//MyMail.BodyEncoding = Encoding.UTF8;
MyMail.BodyFormat = MailFormat.Html;
SmtpMail.SmtpServer = sMailServer;
try
{
SmtpMail.Send(MyMail);
}
catch (Exception ex)
{
return ex;
}

You can try this and make sure you are using valid login credential and you have proper internet connection:
MailMessage mail = new MailMessage();
mail.Subject = "Your Subject";
mail.From = new MailAddress("senderMailAddress");
mail.To.Add("ReceiverMailAddress");
mail.Body = "Hello! your mail content goes here...";
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
NetworkCredential netCre =
new NetworkCredential("SenderMailAddress","SenderPassword" );
smtp.Credentials = netCre;
try
{
smtp.Send(mail);
}
catch (Exception ex)
{
// Handle exception here
}

Where you have configured your client Object. Give complete detail.
Then go through the following post answered by me. You should configure your SmtpClient properly.
