I have a class <code>MyResource</code> in my application that looks like this: <pre><code>public class MyResource : IMyResource { // ... whatever ... } </code></pre> And when I initialize my application in App.xaml.cs I have something like that using Autofac: <pre><code>builder.Register<IMyResource>(container => new MyResource()); </code></pre> Now I need to add a <code>StaticResource</code> in a <code>Window</code> of my WPF application, something like this: <pre><code><Window.Resources> <local:MyResource x:Key="MyResource" /> </Window.Resources> </code></pre> But of course, the whole idea is not to reference a concrete instance of <code>MyResource</code> here. Moreover, I may need to use an instance of <code>MyResource</code> in different <code>Window</code>s or <code>UserControl</code>s across my application. So I would like to use an instance of <code>MyResource</code> as a <code>StaticResource</code> for my <code>Window</code> that is resolved through the Autofac container. How can I achieve this? I was thinking of adding the resource in the code-behind of my <code>Window</code>, but it may create a dependency on my container which I don't want. I was also thinking of doing something like that in App.xaml.cs, when I initialize the application: <pre><code>App.Current.MainWindow.Resources.Add("MyResource", container.Resolve<IMyResource>()); </code></pre> But when I use the resource in my XAML <pre><code><ListBox ItemsSource="{Binding Source={StaticResource ResourceKey=MyResource}}"/> </code></pre> I get an <code>XAMLParseException</code> which inner exception's message stating that the resource named MyResource cannot be found. And even if it was working, I feel like it's a bit smelly. So how can this be achieved? Is it only possible? If not what are the best way to implement this?

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.
