    <p>I got this to work. My specific goal was to load a ResourceDictionary into the App class so I could have custom skins loaded from raw XAML files. Here's how. First, in App.xaml, Add the following:</p> <pre><code> protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); LoadSkin("Skins/Skin1.xaml"); } private void LoadSkin(string FilePath) { XmlReader XmlRead = XmlReader.Create(FilePath); Application.Current.Resources = (ResourceDictionary)XamlReader.Load(XmlRead); XmlRead.Close(); } </code></pre> <p>Create a "bin\Debug\Skins" folder and added a "Skin1.xaml" with the following content:</p> <pre><code>&lt;ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" &gt; &lt;Style x:Key="ButtonAStyle" TargetType="{x:Type Button}"&gt; &lt;Setter Property="Control.Background" Value="Green" /&gt; &lt;Setter Property="Control.Foreground" Value="White" /&gt; &lt;/Style&gt; &lt;/ResourceDictionary&gt; </code></pre> <hr> <p><strong>Specific to Skins</strong></p> <p>In this particular case, you have to make sure you are using the style resources correctly in your individual windows. Here's an example:</p> <pre><code>&lt;Button Name="button1" Style="{DynamicResource ButtonAStyle}" Click="button1_Click" &gt;Button&lt;/Button&gt; </code></pre> <p>Here's a neat trick to try. In button1_Click(), try adding the same code you did in App.OnStartUp() above but with "Skin2.xaml" with "Red" as the background color for your buttons. The skin changes instantly without requiring a reload of the app or window.</p>

    1. CO1. What is your VS version? I don't see such build action "Content Copy to Output" in VS2008? 2. Are you sure that Skin1.xaml is ONLY copied, and not compiled into .exe as a resource?

    2. COI'm using VS 2008. Looks like I fooled myself, though. This works for me if I set "Build Action" to "Content". If I just put loose files in bin\Debug\Skins\, it doesn't work. :-P I'm looking for a fix now.

    3. COFixed. The key was using a XamlReader instead of Application.LoadComponent(). I've updated the code here to reflect it.

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.
