    <p>You can make this super simple. Object oriented programming is the way to go.</p> <p>So say you create a class Order that takes an XElement. I'll write a couple lines for you.</p> <pre><code>public class Order { XElement self; public Order(XElement order) { self = order; } public XElement Element { get { return self; } } public string OrderNumber { // if your xml looks like &lt;Order OrderNumber="somenumber" /&gt; get { return (string)(self.Attribute("OrderNumber") ?? (object)"some default value/null"); } // but if it looks like: &lt;Order&gt;&lt;OrderNumber&gt;somenumber&lt;/OrderNumber&gt;&lt;/Order&gt; // get { return (string)(self.Element("OrderNumber") ?? (object)"some default value/null"); } } } </code></pre> <p>You'll have to fill in the rest of the Order's properties yourself. For each Order value, make a property like the OrderNumber I made above. Having properties for each Order value makes accessing the data super simple.</p> <p>So for your main code you'd have:</p> <pre><code>XElement file = XElement.Load(@"C:\onlinesales\neworders.xml"); Order[] orders = file.Elements("Order").Select(e =&gt; new Order(e)).ToArray(); </code></pre> <p>Now that you have all your orders as individual Order objects, read the data from the list of properties as you output to the file. There's no need now to store the values in StringBuilder's because the values are in the Order objects.</p> <pre><code>foreach(Order order in orders) { // write order.OrderNumber etc. / do whatever you want with the orders. } </code></pre>

    1. COI believe I conceptually understand your suggestion and am trying to implement it, but get an error from the OrderNumber get statement. It is telling me that ?? cannot be applied to XAttribute and String. I am probably missing something very obvious, but I am stuck on it. Do you know why I would be receiving this error?

    2. COI fixed the code: put `(object)` in front of your default value, as long as the default can be cast to string, it should work. `??` is a null replacement operator. So if the first value is null, it returns the second part of the expression instead. So, the compiler, wants both values to be the same basic type.

    3. COThat did fix it yes. For the get statements assigning properties to my class, do I not need a corresponding set to set them to the class? I have added the other properties in the method you suggested, replacing Attribute with Element for everything after OrderNumber.

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.
