    <p>So I am trying to use a custom wpf control on a winforms using:</p> <pre><code>var f = new FileStream (@"C:\sample.xaml", FileMode.Open, FileAccess.Read); var element = XamlReader.Load(f); f.Close(); var elementHost = new ElementHost(); elementHost.Dock = System.Windows.Forms.DockStyle.Fill; elementHost.Child = element; this.Controls.Add(elementHost); </code></pre> <p>I am not experienced in WPF so I don't know how to fix this error.</p> <p>EDIT:</p> <p>So this is the xaml file:</p> <pre><code>&lt;Window x:Class="WpfSample.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:r="http://schemas.aspitalia.com/Ricciolo/Controls" Title="MainWindow" Height="350" Width="525"&gt; &lt;Grid&gt; &lt;Grid.Resources&gt; &lt;XmlDataProvider x:Key="data" Source="Data.xml"&gt; &lt;/XmlDataProvider&gt; &lt;HierarchicalDataTemplate x:Key="dt" ItemsSource="{Binding XPath=outline}"&gt; &lt;/HierarchicalDataTemplate&gt; &lt;/Grid.Resources&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="*" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;r:TreeListView ItemsSource="{Binding Source={StaticResource data},XPath=/opml/body/outline/outline}" ItemTemplate="{StaticResource dt}"&gt; &lt;r:TreeListView.Columns&gt; &lt;GridViewColumn Header="Title" DisplayMemberBinding="{Binding XPath=@title}" Width="150" /&gt; &lt;GridViewColumn Header="Childs" DisplayMemberBinding="{Binding XPath=@count}" Width="100" /&gt; &lt;GridViewColumn Header="Url" DisplayMemberBinding="{Binding XPath=@xmlUrl}" Width="200" /&gt; &lt;/r:TreeListView.Columns&gt; &lt;/r:TreeListView&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>I also got this from a free custom treelistview control on the net, and included both the compiled control and the data.xml in the solution, this xaml uses.</p> <p>EDIT2:</p> <p>Code behind for MainWindow.xaml:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; namespace WpfSample { /// &lt;summary&gt; /// Interaction logic for MainWindow.xaml /// &lt;/summary&gt; public partial class MainWindow : Window { public MainWindow ( ) { InitializeComponent ( ); } } } </code></pre>

    1. COThe problem is (probably) because of `sample.xaml` and the code behind. Could you please provide those two items?

    2. COThanks, will post it in a moment, but the code behind is standard, i.e. I changed nothing.

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).
