JavaScript in UpdatePanel

Javascript events don't work after the UpdatePanel does a partial page update.

An UpdatePanel completely replaces the contents of the update panel on an update. This means that those events you subscribed to are no longer subscribed because there are new elements in that update panel.

Soln1: Re-subscribe to the events I need after every update. I use $(document).ready() for the initial load, then this snippet below to re-subscribe every update.

var prm = Sys.WebForms.PageRequestManager.getInstance();

prm.add_endRequest(function() {
// re-bind your jquery events here
});

The PageRequestManager is a javascript object which is automatically available if an update panel is on the page. You shouldn't need to do anything other than the code above in order to use it as long as the UpdatePanel is on the page.

Soln2: Use jQuery's live() event subscriber
$(document).ready(function () {
$("#Button2").live("click", function () {
alert("test");
});

});

Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'RewriteModule' - HTTP Error 500.19 - Internal Server Err

When I uploaded the site to the server, I got an HTTP Error 500.19 - Internal Server Error which says "Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'RewriteModule'". Error was in the following line in web.config

I got the solution to change the application config file from the following link:
http://support.microsoft.com/kb/942055

But, hosting providers won't allow that on server.

I added the following under  where the RewriteModule is added

Also, there were some virtual directory issues. Hosting provider
changed that. Now it is working.

Issue when using AsyncFileUpload control

I tried to use AsyncFileUpload control in a page. The AsyncFileUpload control was placed inside the first view of a multiview control. The page required a querystring parameter, and if the parameter is not present, the second view of the multiviewcontrol will be shown. This check is made on the Page Load event. This causes issue on the fileupload process. It was giving error, since on the postback, it gets another view. So, I did like this.

on the event "OnClientUploadStarted", I gave a value to a hidden element, and on page load, a checking is made, to see, if the value is given for the hidden element. If the value is given, the view1 itself will be shown without checking the availability of querystring parameter.

Don't know if that is the correct method. Anyhow, it worked.

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay

I have got this issue many times, when I try to send email using smtp. There can be several causes for this. You have to allow relay for mail to be sent to outside servers like gmail.com. For sending mail within your server you don't have to do this. You can find some helps from the following links:
Help1
Help2
Help3

The code I have used is given below:

using System.Net.Mail;


SmtpClient smtpClient = new SmtpClient();
MailMessage message = new MailMessage();
smtpClient.Port = 25;
smtpClient.Host = "smtp.domain.com";
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new System.Net.NetworkCredential("webmail username", "webmail password");
message.From = new MailAddress("webmail username");
message.To.Add("test@gmail.com");
string emailBody = "Hi,

Welcome

";
message.Body = emailBody;
message.Subject = "testing";
message.IsBodyHtml = true;
smtpClient.Send(message);

But, after making the changes on the server, as specified on the above links, I was still getting the same error. Then I added the following line in between the above code.
smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;

Then the error was gone.
