But I can not find how to fix it in this application.
This is the code currently running..
void viewTickets()
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(_myDomain + "/requests.xml"); // working for - rules/651263.xml
request.Method = "GET";
request.Credentials = new NetworkCredential(_Username, _Password);
request.ContentLength = 0;
HttpWebResponse resp = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(resp.GetResponseStream());
string tmp = reader.ReadToEnd();
XDocument Xdoc = XDocument.Parse(tmp);
//Run query
var result = (from etickets in Xdoc.Descendants("record")
select new MyModel
{
eNiceId = _myDomain + "/records/" + etickets.Element("nice-id").Value,
Subject = etickets.Element("subject").Value,
Status = GetTicketStatus(etickets.Element("status-id").Value)
,Description = etickets.Element("description").Value
}).ToList();
if (!IsPostBack)
{
//ViewState["dt"] = result; // I have commented this line in my running code
}
GridView1.DataSource = result; //ViewState["dt"]; If I use ViewState then it is not working here.
GridView1.DataBind();
}
Please can you advice me why I am getting this error?
System.NullReferenceException: Object reference not set to an instance of an object.

Thanks!
I hope that you can use Skynet to upload your proj and so as to let me see it, will you?
From your codes I think your url is something like "http://evolvelogic.zendesk.com/users.xml?query=maduranga001@gmail.com"。However
when I input this URL into address bar, it needs your username and password！So maybe the problem of permission of accessing the site that caused your problem。Please make sure that when you input the address into the address bar，you can fetch the whole，complete
xml contents！
username is the email address and I added the hard coded password in the code for testing. So there not be an issue with the permission. You can see username and the password in my code.
Please ask me if you want any info. I will send it to the private email then.
Did you get enough free time to check my code? If you can advice me for that, then that would be really appreciate.
