    <p>Has anybody else noticed that Bindings with ElementName do not resolve correctly for <code>MenuItem</code> objects that are contained within <code>ContextMenu</code> objects? Check out this sample:</p> <pre><code>&lt;Window x:Class="EmptyWPF.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" x:Name="window"&gt; &lt;Grid x:Name="grid" Background="Wheat"&gt; &lt;Grid.ContextMenu&gt; &lt;ContextMenu x:Name="menu"&gt; &lt;MenuItem x:Name="menuItem" Header="Window" Tag="{Binding ElementName=window}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Grid" Tag="{Binding ElementName=grid}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Menu" Tag="{Binding ElementName=menu}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Menu Item" Tag="{Binding ElementName=menuItem}" Click="MenuItem_Click"/&gt; &lt;/ContextMenu&gt; &lt;/Grid.ContextMenu&gt; &lt;Button Content="Menu" HorizontalAlignment="Center" VerticalAlignment="Center" Click="MenuItem_Click" Tag="{Binding ElementName=menu}"/&gt; &lt;Menu HorizontalAlignment="Center" VerticalAlignment="Bottom"&gt; &lt;MenuItem x:Name="anotherMenuItem" Header="Window" Tag="{Binding ElementName=window}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Grid" Tag="{Binding ElementName=grid}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Menu" Tag="{Binding ElementName=menu}" Click="MenuItem_Click"/&gt; &lt;MenuItem Header="Menu Item" Tag="{Binding ElementName=anotherMenuItem}" Click="MenuItem_Click"/&gt; &lt;/Menu&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>All of the bindings work great except for the bindings contained within the ContextMenu. They print an error to the Output window during runtime.</p> <p>Any one know of any work arounds? What's going on here?</p>

    2. CODo ContextMenus define their own namescope by default?

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).
