    <p>In the MSDN article <a href="http://msdn.microsoft.com/en-us/magazine/cc785480.aspx" rel="noreferrer">Understanding Routed Events and Commands In WPF</a>, it states</p> <blockquote> <p><em>an event will bubble (propagate) up the visual tree from the source element until either it has been handled or it reaches the root element.</em></p> </blockquote> <p>However, in this example, when you click the button, <strong>it doesn't "bubble up the visual tree" to get handled by the parent StackPanel event</strong>, i.e. clicking on the button fires no event.</p> <p>Why not? <strong>What do they mean then by "bubbling up"</strong> if not this?</p> <p><strong>XAML:</strong></p> <pre><code>&lt;Window x:Class="TestClickEvents456.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"&gt; &lt;StackPanel x:Name="TheStackPanel" Background="Yellow" MouseDown="TheStackPanel_MouseDown"&gt; &lt;Button x:Name="TheButton" Margin="10" Content="Click This"/&gt; &lt;TextBlock x:Name="TheMessage" Text="Click the button or the yellow area"/&gt; &lt;/StackPanel&gt; &lt;/Window&gt; </code></pre> <p><strong>code-behind:</strong></p> <pre><code>using System.Windows; using System.Windows.Input; namespace TestClickEvents456 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void TheStackPanel_MouseDown(object sender, MouseButtonEventArgs e) { TheMessage.Text = "StackPanel was clicked."; } } } </code></pre>

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.
