    <p>First of all I know that the title is not so good but the thing is I dont even know how to explain my question; I'll just show an example below on what I'm trying to do:</p> <p><strong>EDIT:</strong> I should have given a better example to begin with; let's try again:</p> <pre><code>// MyAppComponentModel.dll namespace MyAppComponentModel { using System.Collections; interface IResource { } interface IStringResource : IResource { } interface IIconResource : IResource { } interface IDialogResource : IResource { } interface IResourceProvider { void GetResource&lt;T&gt;(out T result, IDictionary criteria = null) where T : IResource; } } // ThirdPartyLib.dll namespace ResourceProviderLibA { using System.Collections; using System.ComponentModel.Composition; using MyAppComponentModel. public sealed class StringResource : IStringResource { ... } public sealed class IconResource : IIconResource { ... } [Export(typeof(IResourceProvider))] public sealed class StringAndIconResourceProvider : IResourceProvider { void IResourceProvider.Get&lt;T&gt;(out T result, IDictionary criteria) { if (typeof(T) == typeof(IDialogResource)) throw new NotSupportedException(); this.InternalGet(out result, criteria); } void InternalGet(out IStringResource result, IDictionary criteria) { result = new StringResource(); ... } void InternalGet(out IIconResource result, IDictionary criteria) { result = new IconResource(); ... } } } // MyMefTestApp.exe namespace MyMefTestApp { using System.Collections.Generic; using System.ComponentModel.Composition.Hosting; using MyAppComponentModel. static class Program { [ImportMany(typeof(IResourceProvider))] private IEnumerable&lt;IResourceProvider&gt; mProviders; static void Main(String[] args) { foreach (var provider in this.mProviders) { ... } } } } </code></pre> <p>I know it's somehow possible and I strongly believe I did something like this once just dont remember how. Anyone?</p> <p>I already know that this can be done via Reflection so please skip those solutions - thanks.</p>

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.
