    <p>I can't understand why happens this. I have a simple application in WPF. This application have a window, and in the App.xaml have defined one style, that changes the style of all the buttons:</p> <pre><code>&lt;Application x:Class="PruebasDesk.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="Window1.xaml"&gt; &lt;Application.Resources&gt; &lt;Style TargetType="{x:Type Button}"&gt; &lt;Setter Property="Height" Value="23"&gt;&lt;/Setter&gt; &lt;Setter Property="Width" Value="75"&gt;&lt;/Setter&gt; &lt;Setter Property="Background" Value="DarkCyan"&gt;&lt;/Setter&gt; &lt;/Style&gt; &lt;/Application.Resources&gt; &lt;/Application&gt; </code></pre> <p>This works fine, all the buttons get the style. Now, here is the problem. If instead of using the StartupUri attribute to start the application, I start it with using the OnStartup method:</p> <pre><code>public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { Window1 win1 = new Window1(); win1.Show(); } } </code></pre> <p>The buttons of the application don't get applied the button style defined at App.xaml. But... if I add another style to the App.xaml, like this:</p> <pre><code>&lt;Application x:Class="PruebasDesk.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" &gt; &lt;Application.Resources&gt; &lt;Style TargetType="{x:Type Button}"&gt; &lt;Setter Property="Height" Value="23"&gt;&lt;/Setter&gt; &lt;Setter Property="Width" Value="75"&gt;&lt;/Setter&gt; &lt;Setter Property="Background" Value="DarkCyan"&gt;&lt;/Setter&gt; &lt;/Style&gt; &lt;Style TargetType="{x:Type TextBox}"&gt; &lt;Setter Property="Height" Value="23"&gt;&lt;/Setter&gt; &lt;Setter Property="Width" Value="180"&gt;&lt;/Setter&gt; &lt;Setter Property="Background" Value="Azure"&gt;&lt;/Setter&gt; &lt;/Style&gt; &lt;/Application.Resources&gt; &lt;/Application&gt; </code></pre> <p>Then the buttons get the style applied!!! This seems really weird to me. Does anyone know if I am missing something?</p>

    2. COThe linik from RichardOD indicates it is a bug and you are already found the fix. Not really the question but I noticed a border in App has a differenent effect than border on the page regarding Tabs.

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.

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