Body
<p>I have the following code which seems to throw a "Invalid cross-thread access." and I can't seem to figure out why. I'm loading a remote xml file from a URL, however, when parsing that XML I always receive this error. Any suggestions?</p> <pre><code>using (StreamReader streamReader = new StreamReader(response.GetResponseStream())) { string xml = streamReader.ReadToEnd(); using (XmlReader reader = XmlReader.Create(new StringReader(xml))) { reader.ReadToFollowing("channel"); reader.MoveToFirstAttribute(); reader.ReadToFollowing("title"); output.AppendLine("Title: " + reader.ReadElementContentAsString()); reader.ReadToFollowing("description"); output.AppendLine("Desc: " + reader.ReadElementContentAsString()); textBox1.Text = output.ToString(); //Invalid cross-thread access. } } </code></pre> <p>The XML I'm trying to parse looks like the following, I'm just trying to parse bits and pieces as I continue to learn how to use c# to parse different types of XML:</p> <pre><code><?xml version="1.0" encoding="utf-8"?> <rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom"xmlns:dc="http://purl.org /dc/elements/1.1/" xmlns:slash="http://purl.org/rss/1.0 /modules/slash/"> <channel> <title>Server &amp; Site News</title> <description>A place for the Admin and Moderators to post the latest news on both the server and site.</description> <pubDate>Fri, 18 May 2012 22:45:08 +0000</pubDate> <lastBuildDate>Fri, 18 May 2012 22:45:08 +0000</lastBuildDate> <generator>Forums</generator> <link>http://removedurl.com/forums/server-site-news.23/</link> <atom:link rel="self" type="application/rss+xml" href="http://removedurl.com/forums/server-site-news.23/index.rss"/> <item> <title>Example Title</title> <pubDate>Mon, 14 May 2012 17:39:45 +0000</pubDate> <link>http://removedurl.com/threads/back-fully-working.11013/</link> <guid>http://removedurl.com/threadsback-fully-working.11013/</guid> <author>Admin</author> <dc:creator>Admin</dc:creator> <slash:comments>14</slash:comments> </item> </channel> </code></pre>

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.
