    <p>I'm using my converter like this:</p> <pre><code>&lt;ControlTemplate TargetType="{x:Type TabItem}"&gt; &lt;Border Name="Border" Background="{Binding Path=ConversationState, Converter={StaticResource conversationStatusConverter}, Mode=TwoWay, NotifyOnSourceUpdated=true, ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}" &gt; </code></pre> <p>This is my triggers definition: </p> <pre><code>&lt;ControlTemplate.Triggers&gt; &lt;Trigger Property="IsSelected" Value="True"&gt; &lt;Setter TargetName="Border" Property="Background" Value="DeepPink" /&gt; &lt;/Trigger&gt; &lt;Trigger Property="IsSelected" Value="False"&gt; &lt;Setter TargetName="Border" Property="Background" Value="LightGray" /&gt; &lt;/Trigger&gt; &lt;/ControlTemplate.Triggers&gt; </code></pre> <p>And my convert back method:</p> <pre class="lang-cs prettyprint-override"><code>public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { if (value.ToString() == "DeepPink") return ConversationStatus.Active; else if (value.ToString() == "Orange") return ConversationStatus.UnseenMessage; else if (value.ToString() == "LightGray") return ConversationStatus.Inactive; else return DependencyProperty.UnsetValue; } </code></pre> <p>When a tab is selected, background goes to deep pink but model is never modified, status stays as before. Source to target works (convert ok), target to source within triggers through isselected property of tab item, doesn't do anything on model. many thanks !</p>

    1. COHow can you say convert (forward) works if status stays as before. A trigger cascading to a converter - I don't think it was intended to be used that way. I don't get why you cannot handle the IsSelected of the TabItem.

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.
