There is an <a href="http://www.hanselman.com/blog/BackToParallelBasicsDontBlockYourThreadsMakeAsyncIOWorkForYou.aspx" rel="nofollow">article by Scott Hanselman</a> in which he describes how to do non blocking requests. Scrolling to the end of it, there is a <code>public Task<bool> ValidateUrlAsync(string url)</code> method. You could modify it like this (could be more robust about response reading) <pre><code>public Task<string> GetAsync(string url) { var tcs = new TaskCompletionSource<string>(); var request = (HttpWebRequest)WebRequest.Create(url); try { request.BeginGetResponse(iar => { HttpWebResponse response = null; try { response = (HttpWebResponse)request.EndGetResponse(iar); using(var reader = new StreamReader(response.GetResponseStream())) { tcs.SetResult(reader.ReadToEnd()); } } catch(Exception exc) { tcs.SetException(exc); } finally { if (response != null) response.Close(); } }, null); } catch(Exception exc) { tcs.SetException(exc); } return tsc.Task; } </code></pre> So with this in hand, you could then use it like this <pre><code>var urls=new[]{"url1","url2"}; var tasks = urls.Select(GetAsync).ToArray(); var completed = Task.Factory.ContinueWhenAll(tasks, completedTasks =>{ foreach(var result in completedTasks.Select(t=>t.Result)) { Console.WriteLine(result); } }); completed.Wait(); //anything that follows gets executed after all urls have finished downloading </code></pre> Hope this puts you in the right direction. PS. this is probably as clear as it can get without using async/await

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.
