    <p>Ok, I was finally able to get the default style like this:</p> <pre><code> using (Stream sw = File.Open(@"C:\TreeViewDefaults.xaml", FileMode.Truncate, FileAccess.Write)) { Style ts = Application.Current.FindResource(typeof(TreeView)) as Style; if (ts != null) XamlWriter.Save(ts, sw); } </code></pre> <p>Which produced:</p> <pre><code>&lt;Style TargetType="TreeView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="VirtualizingStackPanel.IsVirtualizing"&gt; &lt;Setter Property="ItemsControl.ItemsPanel"&gt; &lt;Setter.Value&gt; &lt;ItemsPanelTemplate&gt;&lt;VirtualizingStackPanel IsItemsHost="True" /&gt;&lt;/ItemsPanelTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Trigger.Value&gt; &lt;s:Boolean&gt;True&lt;/s:Boolean&gt; &lt;/Trigger.Value&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;Style.Resources&gt; &lt;ResourceDictionary /&gt; &lt;/Style.Resources&gt; &lt;Setter Property="Panel.Background"&gt; &lt;Setter.Value&gt;&lt;DynamicResource ResourceKey="{x:Static SystemColors.WindowBrushKey}" /&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Border.BorderBrush"&gt; &lt;Setter.Value&gt;&lt;SolidColorBrush&gt;#FF828790&lt;/SolidColorBrush&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Border.BorderThickness"&gt; &lt;Setter.Value&gt;&lt;Thickness&gt;1,1,1,1&lt;/Thickness&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.Padding"&gt; &lt;Setter.Value&gt;&lt;Thickness&gt;1,1,1,1&lt;/Thickness&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="TextElement.Foreground"&gt; &lt;Setter.Value&gt;&lt;DynamicResource ResourceKey="{x:Static SystemColors.ControlTextBrushKey}" /&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="ScrollViewer.HorizontalScrollBarVisibility"&gt; &lt;Setter.Value&gt;&lt;x:Static Member="ScrollBarVisibility.Auto" /&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="ScrollViewer.VerticalScrollBarVisibility"&gt; &lt;Setter.Value&gt;&lt;x:Static Member="ScrollBarVisibility.Auto" /&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.VerticalContentAlignment"&gt; &lt;Setter.Value&gt;&lt;x:Static Member="VerticalAlignment.Center" /&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="TreeView"&gt; &lt;Border BorderThickness="{TemplateBinding Border.BorderThickness}" BorderBrush="{TemplateBinding Border.BorderBrush}" Name="Bd" SnapsToDevicePixels="True"&gt; &lt;ScrollViewer CanContentScroll="False" HorizontalScrollBarVisibility="{TemplateBinding ScrollViewer.HorizontalScrollBarVisibility}" VerticalScrollBarVisibility="{TemplateBinding ScrollViewer.VerticalScrollBarVisibility}" Background="{TemplateBinding Panel.Background}" Padding="{TemplateBinding Control.Padding}" Name="_tv_scrollviewer_" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" Focusable="False"&gt; &lt;ItemsPresenter /&gt; &lt;/ScrollViewer&gt; &lt;/Border&gt; &lt;ControlTemplate.Triggers&gt; &lt;Trigger Property="UIElement.IsEnabled"&gt; &lt;Setter Property="Panel.Background" TargetName="Bd"&gt; &lt;Setter.Value&gt; &lt;DynamicResource ResourceKey="{x:Static SystemColors.ControlBrushKey}" /&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Trigger.Value&gt; &lt;s:Boolean&gt;False&lt;/s:Boolean&gt; &lt;/Trigger.Value&gt; &lt;/Trigger&gt; &lt;Trigger Property="VirtualizingStackPanel.IsVirtualizing"&gt; &lt;Setter Property="ScrollViewer.CanContentScroll" TargetName="_tv_scrollviewer_"&gt; &lt;Setter.Value&gt;&lt;s:Boolean&gt;True&lt;/s:Boolean&gt;&lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Trigger.Value&gt; &lt;s:Boolean&gt;True&lt;/s:Boolean&gt; &lt;/Trigger.Value&gt; &lt;/Trigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>Which, unfortunately, doesn't look helpful. I don't see any properties in there for stopping the auto-scroll-focus thing.</p> <p>Still looking...</p>

Guidance
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).
