    <p>It looks like XamlReader put restrictions on the xaml it loads so it can not contain unknown element names not defined in the loaded xml. Instead use data binding to properties which works fine but requires some code behind. Below code will change the background on the loaded control when user changes the selected item of the comboboxes. You need to add a value converter that converts the colors to human readable names to be used by the comboboxes. </p> <p>XAML:</p> <p></p> <pre><code>&lt;StackPanel&gt; &lt;ComboBox ItemsSource="{Binding Path=AvailableColors}" SelectedValuePath="Color" SelectedValue="{Binding Path=SelectedColors[color0].Color}" /&gt; &lt;ComboBox ItemsSource="{Binding Path=AvailableColors}" SelectedValuePath="Color" SelectedValue="{Binding Path=SelectedColors[color1].Color}" /&gt; &lt;ContentControl Name="newControl" /&gt; &lt;/StackPanel&gt; </code></pre> <p></p> <p>Code behind:</p> <pre><code>using System.Collections.Generic; using System.ComponentModel; using System.Linq; using System.Windows; using System.Windows.Markup; using System.Windows.Media; using System.Xml; namespace LoadTest { public partial class Window1 : Window { public Window1() { InitializeComponent(); SelectedColors = new Dictionary&lt;string, ColorInfo&gt;(); SelectedColors.Add("color0", AvailableColors.First()); SelectedColors.Add("color1", AvailableColors.Last()); XmlReader xaml = XmlReader.Create("newcontrol.xml"); newControl.Content = XamlReader.Load(xaml); newControl.DataContext = SelectedColors; DataContext = this; } public List&lt;ColorInfo&gt; AvailableColors { get { return new List&lt;ColorInfo&gt;() { new ColorInfo() {Color = Colors.Red }, new ColorInfo() { Color = Colors.Green }, new ColorInfo() { Color = Colors.Blue }, new ColorInfo() { Color = Colors.Yellow } }; } } public Dictionary&lt;string, ColorInfo&gt; SelectedColors { get; private set;} } public class ColorInfo : INotifyPropertyChanged { private Color _color; public Color Color { get { return _color; } set { _color = value; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("Color")); } } } public event PropertyChangedEventHandler PropertyChanged; } } </code></pre> <p>XAML file to load (newcontrol.xml):</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;Viewbox xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Document" Stretch="Fill"&gt; &lt;Canvas Height="64" Width="128" ClipToBounds="True"&gt; &lt;Canvas.Background&gt; &lt;LinearGradientBrush StartPoint="1,0"&gt; &lt;GradientStop Color="{Binding Path=[color0].Color}" Offset="0" /&gt; &lt;GradientStop Color="{Binding Path=[color1].Color}" Offset="1" /&gt; &lt;/LinearGradientBrush&gt; &lt;/Canvas.Background&gt; &lt;/Canvas&gt; &lt;/Viewbox&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.

SQuiL has stopped working due to an internal error.

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