<p>Suppose you have a nested element structure, for example a ContextMenu with MenuItems:</p> <pre><code><ContextMenu Style="{StaticResource FooMenuStyle}"> <MenuItem Style="{StaticResource FooMenuItemStyle}"/> ... </ContextMenu> </code></pre> <p>You can easily apply styles or templates to the ContextMenu or MenuItem elements. But if the MenuItem style belongs to the Menu style it is quite cumbersome and redundant to add it to every MenuItem element.</p> <p>Is there any way to apply those automatically to child elements? So that you can simply write this:</p> <pre><code><ContextMenu Style="{StaticResource FooMenuStyle}"> <MenuItem/> ... </ContextMenu> </code></pre> <p>It would be neat if FooMenuStyle could style containing MenuItem elements, but that does not seem to be possible.</p> <p>Edit: The Menu example is probably misleading since I was unaware of ItemContainerStyle and the intent was for a general solution. Based on the two answers I have come up with two solutions: one general variant and one for ItemContainerStyle and the like:</p> <pre><code><Style x:Key="FooMenuItem" TargetType="{x:Type MenuItem}"> ... </Style> <Style x:Key="FooMenu" TargetType="{x:Type ContextMenu}">  <Setter Property="ItemContainerStyle" Value="{StaticResource FooMenuItem}"/>  <Style.Resources> <Style TargetType="{x:Type MenuItem}" BasedOn="{StaticResource FooMenuItem}"/> </Style.Resources> </Style> <ContextMenu Style="{StaticResource FooMenu}"> <MenuItem/> </ContextMenu> </code></pre>

Guidance

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.
