    <p>I've been writing a WPF program at work that uses a custom <code>AnimatedScrollViewer</code>control, inheriting from <code>ScrollViewer</code>. It has the following default template:</p> <pre><code>&lt;Style TargetType="{x:Type Controls:AnimatedScrollViewer}"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type Controls:AnimatedScrollViewer}"&gt; &lt;Grid x:Name="PART_LayoutRoot"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="*" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;ScrollContentPresenter x:Name="PART_ScrollContentPresenter" /&gt; &lt;Grid Grid.Row="1"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;ScrollBar x:Name="PART_HorizontalScrollBar" Orientation="Horizontal" IsEnabled="{TemplateBinding IsPaused}" Value="{TemplateBinding HorizontalOffset}" Maximum="{TemplateBinding ScrollableWidth}" ViewportSize="{TemplateBinding ViewportWidth}" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" /&gt; &lt;StackPanel Grid.Column="1"&gt; &lt;Image Source="{StaticResource LockedImage}" Visibility="{TemplateBinding IsPlaying, Converter={StaticResource boolToVisConverter}}"/&gt; &lt;Image Source="{StaticResource UnlockedImage}" Visibility="{TemplateBinding IsPaused, Converter={StaticResource boolToVisConverter}}"/&gt; &lt;/StackPanel&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>I'm setting this as the default style using:</p> <pre><code>[...] public class AnimatedScrollViewer : ScrollViewer { static AnimatedScrollViewer() { DefaultStyleKeyProperty.OverrideMetadata(typeof(AnimatedScrollViewer), new FrameworkPropertyMetadata(typeof(AnimatedScrollViewer))); } [...] </code></pre> <p>The style is being referenced in the below <code>Generic.xaml</code> dictionary, which in turn is referenced as a <code>MergedDictionary</code> in <code>App.xaml</code>:</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;ResourceDictionary.MergedDictionaries&gt; &lt;ResourceDictionary Source="ConvertersDictionary.xaml" /&gt; &lt;ResourceDictionary Source="pack://application:,,,/JamesWright.Utils.EndpointCaller.Views;component/Themes/EndpointStyles.xaml" /&gt; &lt;ResourceDictionary Source="pack://application:,,,/JamesWright.Utils.EndpointCaller.Views;component/Themes/ImageResources.xaml" /&gt; &lt;ResourceDictionary Source="pack://application:,,,/JamesWright.Utils.EndpointCaller.Views;component/Themes/Resources.xaml" /&gt; &lt;ResourceDictionary Source="pack://application:,,,/JamesWright.Utils.EndpointCaller.Views;component/Controls/AnimatedScrollViewer.xaml" /&gt; &lt;/ResourceDictionary.MergedDictionaries&gt; &lt;/ResourceDictionary&gt; </code></pre> <p>What's really strange is that the style is only applied to the control when the program runs on my own machine and a Windows 8.1 virtual machine, while it isn't applied on my colleague's computer and a team machine. I know that the style isn't applied because the associated <code>ScrollBar</code> should only be enabled when 'IsPaused' is true. On my colleague's machine, however, it's always enabled. Also, the images that I've specified in the template don't appear as a result.</p> <p>Are there any known reasons why a <code>Style</code> may not be applied on certain machines? I've decompiled the app and the resources are referencing the correct files. Any help is appreciated, as we've been pulling our hair out all day :P</p> <p><strong>UPDATE:</strong> I've downloaded it to my Windows 8 laptop and the style is applied correctly.</p> <p><strong>UPDATE #2:</strong> I attempted to use relative paths as opposed to <code>pack</code> syntax with no success</p>

    1. CODid you try using the relative path instead of pack uri syntax? <ResourceDictionary Source="/Themes/EndpointStyles.xaml"/> or changing pack URI to <ResourceDictionary Source="pack://application:,,,/Themes/EndpointStyles.xaml"/>

    2. COI'm using the `pack` syntax as `Generic.xaml` is in a different assembly, although I could try placing them in the same project.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
