    <p>I defined two classes. First one...</p> <pre><code>[Serializable] public class LocalizationEntry { public LocalizationEntry() { this.CatalogName = string.Empty; this.Identifier = string.Empty; this.Translation = new Dictionary&lt;string, string&gt;(); this.TranslationsList = new List&lt;Translation&gt;(); } public string CatalogName { get; set; } public string Identifier { get; set; } [XmlIgnore] public Dictionary&lt;string, string&gt; Translation { get; set; } [XmlArray(ElementName = "Translations")] public List&lt;Translation&gt; TranslationsList { get { var list = new List&lt;Translation&gt;(); foreach (var item in this.Translation) { list.Add(new Translation(item.Key, item.Value)); } return list; } set { foreach (var item in value) { this.Translation.Add(item.Language, item.Text); } } } } </code></pre> <p>...where <code>public List&lt;Translation&gt; TranslationsList</code> is a wrapper for non-serializable <code>public Dictionary&lt;string, string&gt; Translation</code>.</p> <p>Pair of key and value is defined as follows:</p> <pre><code>[Serializable] public class Translation { [XmlAttribute(AttributeName = "lang")] public string Language { get; set; } [XmlText] public string Text { get; set; } public Translation() { } public Translation(string language, string translation) { this.Language = language; this.Text = translation; } } </code></pre> <p>At last code used to serialize:</p> <pre><code>static void Main(string[] args) { LocalizationEntry entry = new LocalizationEntry() { CatalogName = "Catalog", Identifier = "Id", }; entry.Translation.Add("PL", "jabłko"); entry.Translation.Add("EN", "apple"); entry.Translation.Add("DE", "apfel"); using (FileStream stream = File.Open(@"C:\entry.xml", FileMode.Create)) { XmlSerializer serializer = new XmlSerializer(typeof(LocalizationEntry)); serializer.Serialize(stream, entry); } LocalizationEntry deserializedEntry; using (FileStream stream = File.Open(@"C:\entry.xml", FileMode.Open)) { XmlSerializer serializer = new XmlSerializer(typeof(LocalizationEntry)); deserializedEntry = (LocalizationEntry)serializer.Deserialize(stream); } } </code></pre> <p>The problem is that after deserialization <code>deserializedEntry.TranslationsList</code> is empty. I set a breakpoint at setter of <code>LocalizationEntry.TransalionsList</code> and it comes from deserializer empty as well. Product of serialization is of course valid. Is there any gap in my code?</p> <p>EDIT:</p> <p>Here is generated XML:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;LocalizationEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;CatalogName&gt;Catalog&lt;/CatalogName&gt; &lt;Identifier&gt;Id&lt;/Identifier&gt; &lt;Translations&gt; &lt;Translation lang="PL"&gt;jabłko&lt;/Translation&gt; &lt;Translation lang="EN"&gt;apple&lt;/Translation&gt; &lt;Translation lang="DE"&gt;apfel&lt;/Translation&gt; &lt;/Translations&gt; &lt;/LocalizationEntry&gt; </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.
