HttpWebRequest request = (HttpWebRequest) WebRequest.Create(URL); // Set the ContentType property of the WebRequest. request.ContentType = "application/x-www-form-urlencoded"; // Set the Method property of the request to POST. request.Method = "POST"; // start the asynchronous operation request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback),request); allDone.WaitOne(); } private static void GetRequestStreamCallback(IAsyncResult asynchronousResult) { HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState; // End the operation Stream postStream = request.EndGetRequestStream(asynchronousResult); // Convert the string into a byte array. byte[] byteArray = Encoding.UTF8.GetBytes(""); // Write to the request stream. postStream.Write(byteArray, 0, postData.Length); postStream.Close(); // Start the asynchronous operation to get the response request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request); } private static void GetResponseCallback(IAsyncResult asynchronousResult) { //..... Form1 test = new Form1(); test.statusLabel.Text = responseString; //dont write anything Console.WriteLine(responseString); //works well //..... } </code></pre> <p>How can I change it?</p> <p><strong>UPDATE: Add more code</strong>.

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.
