    <p>I have a custom ContentControl </p> <pre><code>public class DataControl : ContentControl { public List&lt;DataItem&gt; Options { get { return (List&lt;DataItem&gt;)GetValue(OptionsProperty); } set { SetValue(OptionsProperty, value); } } public static readonly DependencyProperty OptionsProperty = DependencyProperty.Register("Options", typeof(List&lt;DataItem&gt;), typeof(DataControl)); public DataControl() { Options = new List&lt;DataItem&gt;(); } public string Label { get { return (string)GetValue(LabelProperty); } set { SetValue(LabelProperty, value); } } // Using a DependencyProperty as the backing store for Label. This enables animation, styling, binding, etc... public static readonly DependencyProperty LabelProperty = DependencyProperty.Register("Label", typeof(string), typeof(DataControl)); } public class DataItem { public DataItem(string key, string value) { Key = key; Value = value; } public string Key { get; set; } public string Value { get; set; } } </code></pre> <p>whose template is applied by the following Style:</p> <pre><code>&lt;Style TargetType="{x:Type local:DataControl}" x:Key="DefaultStyle"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type local:DataControl}"&gt; &lt;StackPanel&gt; &lt;ListBox ItemsSource="{TemplateBinding Options}" &gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Label Content="{Binding Key}" /&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; &lt;Label Content="{TemplateBinding Label}" /&gt; &lt;/StackPanel&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>If I use a XamlWriter to Save this style and then read it back again, the ItemsSource binding is lost, but the Content binding on the Label isn't. </p> <pre><code>Style style = Application.Current.TryFindResource("DefaultStyle") as Style; string s = XamlWriter.Save(style); Style secondStyle = XamlReader.Parse(s) as Style; </code></pre> <p>Is there a way to ensure the ItemsSource binding is serialized correctly or to add it back in easily?</p> <p>This also occurs when trying to get the Style from a ResourceDictionary from another project, e.g.</p> <pre><code>ResourceDictionary styles = new ResourceDictionary(); styles.Source = new Uri(String.Format("pack://application:,,,/StyleCopyTest;component/Styles/{0}Styles.xaml", type)); return styles; </code></pre>

    1. CODid you try the solution in [http://stackoverflow.com/questions/32541/how-can-you-clone-a-wpf-object](http://stackoverflow.com/questions/32541/how-can-you-clone-a-wpf-object)?

    2. COI have and it doesn't resolve the issue. The .Net 4.0 solution doesn't keep the ItemsSource binding and worse loses the Content binding on the Label in the ListBox.ItemTemplate. Creating an ExpressionConverter fixes the Content binding but still does not save the ItemsSource binding.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
