    <p>I'm saving 2-dimensional coordinates on an XML file with a structure similar to:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;grid&gt; &lt;coordinate time="78"&gt; &lt;initial&gt;540:672&lt;/initial&gt; &lt;final&gt;540:672&lt;/final&gt; &lt;/coordinate&gt; &lt;/grid&gt; </code></pre> <p>I can open the XML file and read it via the XmlTextReader, but how do I loop through the coordinates specifically to retrieve both the time attribute and data between the initial and final nodes in some format similar to:</p> <pre><code>string initial = "540:672"; string final = "540:672"; int time = 78; </code></pre> <hr> <h2>New Code:</h2> <p>My New Code:</p> <pre><code>//Read the XML file. XDocument xmlDoc = XDocument.Load("C:\\test.xml"); foreach (var coordinate in xmlDoc.Descendants("coordinate")) { this.coordinates[this.counter][0] = coordinate.Attribute("time").Value; this.coordinates[this.counter][1] = coordinate.Element("initial").Value; this.coordinates[this.counter][2] = coordinate.Element("final").Value; this.counter++; }; </code></pre> <p>but now I get this error:<br> "Object reference not set to an instance of an object."</p> <hr> <p>XML</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;grid&gt; &lt;coordinate time="62"&gt; &lt;initial&gt;540:672&lt;/initial&gt; &lt;final&gt;540:672&lt;/final&gt; &lt;/coordinate&gt; ... &lt;coordinate time="46"&gt; &lt;initial&gt;176:605&lt;/initial&gt; &lt;final&gt;181:617&lt;/final&gt; &lt;/coordinate&gt; &lt;/grid&gt; </code></pre> <p>Skipped a few coordinate tags to fit, but they all had the time attribute and initial/final subtags.</p> <hr> <p>Globals</p> <pre><code>uint counter = 0; // Coordinates to be retrieved from the XML file. string[][] coordinates; </code></pre>

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.
