    <p>Chuck has a good approach. Sometimes, you don't want to retain the reference to the underlying xml data structure in the model object you are loading. In this case, I often use a pattern like this:</p> <pre><code>public interface IXmlReadable { void Clear(); void Read(XPathNavigator xmlNav); } public class ModelBase : IXmlReadable { public void Clear() { DoClear(); } public void Read(XPathNavigator xmlNav) { DoRead(xmlNav); } protected virtual void DoClear() { throw new NotImplementedException(); } protected virtual void DoRead(XPathNavigator xmlNav) { throw new NotImplementedException(); } } </code></pre> <p>Read can be overloaded to accept <code>XmlDocument</code>, <code>XmlNode</code>, <code>XElement</code>, etc.</p> <p>Now you can implement specific models.</p> <pre><code>public sealed class Order : ModelBase { public Order() { } public string OrderNumber { get; private set; } protected override void DoClear() { OrderNumber = string.Empty; } protected override void DoRead(XPathNavigator xmlNav) { DoClear(); XPathNavigator node; node = xmlNav.SelectSingleNode("OrderNumber"); if (node != null) OrderNumber = node.InnerXml; // implement other properties here } } </code></pre> <p>With the XPathDocument and XPathNavigator approach, you can then do something like this:</p> <pre><code>XPathDocument xml = new XPathDocument(@"C:\onlinesales\neworders.xml"); xmlNav = xml.CreateNavigator(); XPathNodeIterator iterator = xmlNav.Select("Order"); while (iterator.MoveNext()) { Order order = new Order(); order.Read(iterator.Current); // do something with the Order - add to list or process } </code></pre>

    1. COInteresting. Is typo in the last code segment - should be `order.Read()` and not `Order.Read()`?

    2. COOops! Yes, typo. You call read on the instance to do the read work. I have corrected the code.

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.
