    <p>I have a WPF UserControl, which I use in a WinForms Control within an ElementHostControl. Then I start a WPF Window, while the Windows Form is still open. If I then close the WPF Window, and try to add a Child Element to my WPF UserControl, it crashes at "InitializeComponent()" (of the Child Element) with the exception:</p> <blockquote> <p>"A first chance exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll. Additional information: This element is not currently associated with any context"</p> </blockquote> <p>I found out why it happens, but I don't know how to solve the problem. If I leave out this code:</p> <pre><code>public static void EnsureApplicationResources() { if (Application.Current == null) { // create the Application object new Application(); string assemblyName = System.IO.Path.GetFileNameWithoutExtension( Assembly.GetExecutingAssembly().ManifestModule.Name); // merge in your application resources Application.Current.Resources.MergedDictionaries.Add( Application.LoadComponent(new Uri("/KolonistenClient;component/KolonistenResourceDictionary.xaml", UriKind.RelativeOrAbsolute)) as ResourceDictionary); } } </code></pre> <p>then everything is fine. I need that though, because of the fact that my ResourceDictionary (and thus also my defined styles and templates) is otherwise not available throughout the WPF Window and Controls. <a href="http://drwpf.com/blog/2007/10/05/managing-application-resources-when-wpf-is-hosted/" rel="nofollow noreferrer">This I found out about here</a></p> <p>Is there any way to combine the best of both worlds? Keeping my ResourceDictionary, while preventing the application from crashing?</p>

    1. COBTW: I tried calling the EnsureApplicationResources() method in my UserControl and in my WPF Window (both before InitializeComponent). Both ways resulted in the same crash as described in my question.

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.
