    <p>I have <code>UserControl</code> bounded to my view model. View model implements <code>IDataErrorInfo</code>. <code>UserConrol</code> has <code>Validation.ErrorTemplate</code>. In this template I use converter to show tooltip with errors:</p> <pre><code>&lt;UserControl.Style&gt; &lt;Style TargetType="{x:Type UserControl}"&gt; &lt;Setter Property="Validation.ErrorTemplate"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate&gt; &lt;DockPanel&gt; &lt;AdornedElementPlaceholder x:Name="adorner"&gt; &lt;Image x:Name="imgError" Width="32" Height="32" Margin="5" HorizontalAlignment="Left" VerticalAlignment="Bottom" ToolTip="{Binding ElementName=adorner,Path=AdornedElement.(Validation.Errors),Converter={StaticResource ValidationErrors2TooltipConverter},ConverterParameter='Couldn't save hour work:'}" Source="{StaticResource ErrorDrawingImage}" /&gt; &lt;/AdornedElementPlaceholder&gt; &lt;/DockPanel&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; &lt;/UserControl.Style&gt; </code></pre> <p>When I change some property (for instance: <code>ComboBox</code>'s selection), the number of error should change, but it doesn't. I couldn't find a way to refresh errors in <code>ToolTip</code>.</p> <p><strong>Questions:</strong></p> <ol> <li>How could I refresh errors in <code>ToolTip</code>.</li> <li>Validation works fine for <code>UserControl</code>, but doesn't work for components inside it. I defined <code>Validation.ErrorTemplate</code>'s for components in <code>UserControl</code>, but they are not visible, however controls bounded to view models (with <code>IDataErrorInfo</code>).</li> </ol>

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.
