        <br />
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></div>
    </form>
</body>
</html>

and i have a Function that sends the e-mail like this

private static string SendEmail(String from, string to, string cc,int port, string subject, string message,String Host)
    {
        //create the mail message
        System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
        //set the content
        mail.From = new System.Net.Mail.MailAddress(from,"Test E-mail");

        mail.Subject = subject;

        mail.Body = message;
        
        mail.IsBodyHtml = false;
        
        
        //send the message
        //SmtpClient smtp = new SmtpClient("196.35.193.28");     // use this Smtp Server
        // seems we can use either the big routing server or our own ip address
        System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
       
        smtp.Port = port;
        
        smtp.Host = Host;
         //mailSenderInstance.Credentials = New System.Net.NetworkCredential("LoginAccout", "Password") 
        smtp.Credentials = new System.Net.NetworkCredential("administrator", "skskssk");
 
        try
        {
            smtp.Send(mail);
            return "Mail sent successfully!";
        }
        catch (Exception ex)
        {
            Exception ex2 = ex;
        
            string errorMessage = string.Empty;

            while (ex2 != null)
            {
                errorMessage += ex2.ToString();
            
                ex2 = ex2.InnerException;
            }

            return errorMessage;
        }
        // Mailbox unavailable. The server response was 5.7.1. Unable to relay for (name).
        // see notes under Techdocs
        //client.Host = "localhost";  // setup the server / host sending the mail
        // client.UseDefaultCredentials = true;

    }

and in my button send we have the following

protected void btnSend_Click(object sender, EventArgs e)
   {
      Label1.Text =  SendEmail(txtFrom.Text, txtto.Text, txtcc.Text, Convert.ToInt32(txtport.Text), txtsubject.Text,txtbody.Text,txthost.Text);

   }

I have entered the Following in the Required Fields when i test the application

To: Vuyiswa@its.co.za

From:Vuyiswa@its.co.za

CC:vuyiswamb@gmail.com
Subject: This is the Test for the mail in o!booking System
BodyIf you Receive this e-mail Please confirm the receipt of this e-mail
Port : 25
Host:  mailserver.Vuyiswa.local

When i run my Application and clicking on the send button , i get the Following Error

System.InvalidOperationException: A recipient must be specified. at System.Net.Mail.SmtpClient.Send(MailMessage message) at _Default.SendEmail(String from, String to, String cc, Int32 port, String subject, String message, String Host) in c:\Vuyiswa\Email_test\Default.aspx.cs:line 51

As suggested by error and looking at your code i found that you have not add the recipient whom you want to send the mail.I think you miss that
Just Add
mail.To = new System.Net.Mail.MailAddress(to,"Test E-mail");

Sounds like your mail server needs configuring.

Why not use your own mail server, from your ISP, to test ? Or just tell your boss, I need a proper mail server to test this code.

Good Morning Christian

i came across this code

protected void Button1_Click(object sender, EventArgs e)
  {
      MailMessage mm = new MailMessage();

      SmtpClient smtp = new SmtpClient();

      mm.From = new MailAddress("Vuyiswa@its.co.za");

      mm.To.Add(new MailAddress("Vuyiswa@its.co.za"));

      mm.To.Add(new MailAddress("RDG@its.co.za"));

      mm.Subject = "Hello";

      mm.Body = "<p>This is the E-mail Test for !Booking System</p>";

      mm.IsBodyHtml = true;

      smtp.Host = "smtp.gmail.com";

      smtp.EnableSsl = true;

      System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();

      NetworkCred.UserName = "vuyiswamb@gmail.com";

      NetworkCred.Password = "secret";

      smtp.UseDefaultCredentials = true;

      smtp.Credentials = NetworkCred;

      smtp.Port = 587;

      smtp.Send(mm);
  }

This code works in Gmail, i will contact the Server Administrator to tell me exactly what port and credetials do i need to use, because i get Port errors.

Thanks for your help

Your best way of doing this is to make your databound value be passed into a code behind method, which would then parse it and return the result to show or hide the sign.

Hi sir,

I have created dynamic imagebuttons. In that postbackurl was not working. So i wrote addhandler. I want to open selected image in new window. How to call the selected image id or get the imageurl in img_Click event..?

Dim tRow5 As New HtmlTableRow()
tblParticulars.Rows.Add(tRow5)
tCell = New HtmlTableCell()
tCell.Align = "Left"
tCell.Width = 300
Dim Img As New ImageButton
Img.ID = "AdvImg" & cnt

Txt1 = Ds1.Tables(0).Rows(i).Item("AdvImg")
Img.ImageUrl = "~/Photos/" & Txt1
Img.Height = "70"
Img.Width = "60"
AddHandler Img.Click, AddressOf Me.Img_Click
tCell.Controls.Add(Img)
tRow5.Cells.Add(tCell)

Private Sub img_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)

End Sub

you have to give events like :(in C#)
Img.Click += new EventHandler(Imgbtn_Click);

This will fire the event:
protected void Imgbtn_Click(object sender, EventArgs e)
{
//your code here
}
