I'm using LINQ to XML I'm having a bear of a time figuring out why I'm getting NullReferenceException on the MyUrl portion of the LINQ selection below. What am I missing? <pre><code> XElement xmlRssItems = XElement.Parse(e.Result); podlist.ItemsSource = from rssItem in xmlRssItems.Element("channel").Elements("item") where rssItem.Element("enclosure") != null select new PodcastItem { Title = (string)rssItem.Element("title"), MyUrl = new Uri(rssItem.Element("enclosure").Attribute("url").Value) }; </code></pre> ... <pre><code>public class PodcastItem { public string Title { get; set; } public Uri MyUrl { get; set; } } </code></pre> XML: <pre><code><rss> <channel> <item> <guid isPermaLink="false">tag:blogger.com,1999:blog-811823720557864449.post-3786706865099847612</guid> <pubDate>Sun, 20 Feb 2011 02:08:00 +0000</pubDate> <title>#43 - StarCast: "Mork's Homecoming!"</title> <link>http://starcastshow.blogspot.com/2011/02/43-starcast-morks-homecoming.html</link> <author>starcastshow@gmail.com (Garrett Weinzierl &amp; Kyle Fergusson)</author> <thr:total>1</thr:total> <enclosure url="http://feedproxy.google.com/~r/starcast_rss/~5/Xf0YXRRMrPU/episode_43.mp3" length="0" type="audio/mpeg" /> <feedburner:origEnclosureLink>http://thestarcast.com/shows/starcast/episode_43.mp3</feedburner:origEnclosureLink> </item> </code></pre> THE ISSUE: *THE PROBLEM WAS THAT IN THE RSS FEED THERE WAS ONE NODE THAT DIDN'T HAVE AN ENCLOSURE ITEM. I ADDED A SIMPLE CHECK FOR NULL AND IT WORKS PERFECTLY. THANKS FOR THE SANITY CHECK.*

Guidance

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.
