Problem: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. c25sm1228430ika.11
Solution:
Public Shared Sub SendEmail()
Dim Message As New Net.Mail.MailMessage()
Dim FromEmail As New Net.Mail.MailAddress(“From Email Address”)
Message.From = FromEmail
Message.To.Add(“To Email Address”)
Message.Subject = “Subject of the Email”
Message.Body = “Body of the Email”
‘Message.SubjectEncoding = System.Text.Encoding.UTF8
‘Message.BodyEncoding = System.Text.Encoding.UTF8
‘Message.IsBodyHtml = False
‘Message.Priority = Net.Mail.MailPriority.High
Dim SmtpClient As New Net.Mail.SmtpClient(“smtp.YourEmailServer.com”, PortNo eg: 587 for gmail )
SmtpClient.EnableSsl = True
’smtp.DeliveryMethod = Net.Mail.SmtpDeliveryMethod.Network
’smtp.UseDefaultCredentials = False
SmtpClient.Credentials = New Net.NetworkCredential(“YourEmailAddress”, “YourEmailPassword”)
SmtpClient.Send(Message)
End Sub
Note: An important point to note is that you have to set the EnableSSl to True before you set the NetWork Credentials of your SMTP client.

If you are using AJAX then the only way i have found yet to give an alert to a user on return to the Asynchronous post back is to add an “end request” handler to the PageRequestManager.
In this way you can tell the request manager to run a javascript function on returning from a Asynchronous post back event of AJAX.
Code for doing this is :
function load()
{
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}
where “EndRequestHandler” will be the name of your javascript function you want to call.
Call the above function in Onload event of <body> tag:
<body onload=”load()”>
function EndRequestHandler()
{
alert(“You record has been saved successfully”);
}
Now If you want to give a different message based on your logic in server side code (code behind) then you can use a server side Hidden Field:
<input id=”hdnValue” type=”hidden” runat=”server” value=”" />
Set its value in server side code on Asychronous Post Back:
Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCreateSample.Click
If condition Then
hdnValue.value = “do this”
Else
hdnValue.value = “do that”
End If
End Sub
Now you can check the value of this Hidden Field in your Client Side EndRequestHandler function and give a different alert to user based on its value:
function EndRequestHandler()
{
if (document.getElementById(‘<%= hdnValue.ClientID %>’).value == “do this”)
{
alert(“You record has been saved successfully”);
}
else
{
alert(“There is an error”);
}
}
