There's actually two parts to your problem that I can. <ol> <li>Get a book object from known Id</li> <li>Create a new book object</li> </ol> To retrieve the object: <pre><code> public class Book { public Book(string id, string name, decimal price) { Id = id; Name = name; Price = price; } public string Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } } </code></pre> To load the book with known Id into the object: <pre><code>XmlDocument xmlDocument = new XmlDocument(); xmlDocument.Load(_path); XmlNode xmlNode = xmlDocument.SelectSingleNode(@"//book[@id='" + id + "']"); return xmlNode == null ? new Book(id, string.Empty, 0) : new Book(id, xmlNode.Attributes["name"].Value, decimal.Parse(xmlNode.Attributes["price"].Value)); </code></pre> To create a new book element: <pre><code>XmlDocument xmlDocument = new XmlDocument(); xmlDocument.Load(_path); XmlElement newBook = xmlDocument.CreateElement("book"); newBook.SetAttribute("id", book.Id); newBook.SetAttribute("name", book.Name); newBook.SetAttribute("price", book.Price.ToString()); xmlDocument.DocumentElement.AppendChild(newBook); xmlDocument.Save(_path); </code></pre> Where _path is the path to your XML document. I hope this helps. Also remember that XmlDocument is an in-memory or cached tree representation of an XML document. It is somewhat resource-intensive, if you have a large XML document and not enough memory to consume, use XmlReader and XmlWriter for better performance.

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.
