    <p>For class we have to follow a tutorial to create a silverlight website that searches DIGG for a given topic. (Using this tutorial as a base: <a href="http://weblogs.asp.net/scottgu/archive/2010/02/22/first-look-at-silverlight-2.aspx" rel="nofollow">http://weblogs.asp.net/scottgu/archive/2010/02/22/first-look-at-silverlight-2.aspx</a>)</p> <p>We have to use the following code to fetch the information from DIGG.</p> <pre><code> private void buttonSearch_Click(object sender, RoutedEventArgs e) { string topic = textboxSearchTopic.Text; WebClient digg = new WebClient(); digg.DownloadStringCompleted += new DownloadStringCompletedEventHandler(digg_DownloadStringCompleted); digg.DownloadStringAsync( new Uri("http://services.digg.com/1.0/story.getAll?count=10&amp;topic="+topic)); } void digg_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { if (e.Error != null) { DisplayStories(e.Result); } } private void DisplayStories(string xmlContent) { XDocument document = XDocument.Parse(xmlContent); var stories = from story in document.Descendants("story") where story.Element("thumbnail")!=null select new DiggStory { Id = (string)story.Attribute("id"), Title = (string)story.Element("title"), Description = (string)story.Element("description"), ThumbNail = (string)story.Element("thumbnail").Attribute("src"), HrefLink = (string)story.Attribute("link"), NumDiggs = (int)story.Attribute("diggs") }; gridStories.ItemsSource = stories; } </code></pre> <p>And when bushing the buttonSearch, We get the error: </p> <pre><code>An exception occurred during the operation, making the result invalid. Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at System.Net.OpenReadCompletedEventArgs.get_Result() at DiggSample.Views.Search.Digg_OpenReadCompleted(Object sender, OpenReadCompletedEventArgs e) at System.Net.WebClient.OnOpenReadCompleted(OpenReadCompletedEventArgs e) at System.Net.WebClient.OpenReadOperationCompleted(Object arg) </code></pre> <p>I already know the Digg API is outdated, but I do not think this error has anything to do with it. (We even get a local XML file, which we can use but it still doesn't work)</p> <p>I have no idea what is causing this and we aren't get much help from our teacher, so I hope somebody can help us.</p> <p>Thanks, Thomas</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.
