    <p>I've had a look here <a href="https://stackoverflow.com/questions/4158448/c-sharp-webrequest-using-cookies">C# WebRequest using Cookies</a> <a href="https://stackoverflow.com/questions/787857/multiple-webrequest-in-same-session">Multiple WebRequest in same session</a> <a href="https://stackoverflow.com/questions/9025075/reuse-connection-with-httpwebrequest-in-c-sharp">Reuse Connection with HttpWebRequest in C#</a> <a href="https://stackoverflow.com/questions/1453560/c-sharp-keep-session-id-over-httpwebrequest">C# keep session id over httpwebrequest</a></p> <p>And that's what I'm doing except I wish to store my CookieContainer as a member (named session_cookie) in my class called connector. My problem is that if I use a temporary object in my code then the cookies work fine:</p> <pre><code>CookieContainer t = new CookieContainer(); HTTPReq = (HttpWebRequest)WebRequest.Create(scriptURL); HTTPReq.CookieContainer = t; </code></pre> <p>But if I use </p> <pre><code>HTTPReq = (HttpWebRequest)WebRequest.Create(scriptURL); HTTPReq.CookieContainer = session_cookie; </code></pre> <p>Then it doesn't work! I cannot figure out why</p> <p>Here is the connector class code:</p> <pre><code>public class Connector { public CookieContainer session_cookie; private string session_id; private HttpWebRequest HTTPReq; private HttpWebResponse Response; //Session oriented connection public string serverRequest(string scriptURL, string payLoad) { try { HTTPReq = (HttpWebRequest)WebRequest.Create(scriptURL); HTTPReq.CookieContainer = session_cookie; HTTPReq.Method = "POST"; //Data arguments byte[] byteArray = Encoding.UTF8.GetBytes(payLoad); HTTPReq.ContentType = "application/x-www-form-urlencoded"; HTTPReq.ContentLength = byteArray.Length; //Get the stream to write into Stream dataStream = HTTPReq.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); Response = (HttpWebResponse)HTTPReq.GetResponse(); Encoding enc = Encoding.GetEncoding(1252); // Western latin alphabet (windows default) //Get the repsonse from the server StreamReader ResponseStream = new StreamReader(Response.GetResponseStream(), enc); string response = ResponseStream.ReadToEnd().Trim(); Response.Close(); ResponseStream.Close(); return response; } catch (WebException ex) { Console.WriteLine(ex.ToString()); return null; } } } </code></pre> <p>Any ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
