I want to style a <code>TabItem</code>'s "focus rectangle". I've learned I can do this using <code>FocusVisualStyle</code>. The problem is that <a href="http://msdn.microsoft.com/en-us/library/bb613567.aspx" rel="nofollow"><code>FocusVisualStyle</code> creates a sepearate visual tree for an adorner that is drawn on top of the control</a>. I use complex semi-transparent controls and drop-shadow effects, and I need to show the rectangle under certain elements that are part of the <code>TabItem.Template</code>. I've found on MSDN that I can use <a href="http://msdn.microsoft.com/en-us/library/bb613567.aspx#Alternatives" rel="nofollow"><code>IsKeyboardFocused</code> combined with trigger</a> to achieve what I need. However <a href="http://social.msdn.microsoft.com/Forums/en/wpf/thread/dec15e4b-bbc5-47b7-ad44-76f039d7b53f" rel="nofollow">further research</a> have shown <a href="http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/aaf7ec00-8470-4086-86da-2a8c1467bb04/" rel="nofollow">this is not correct</a>, because: <blockquote> Keyboard focus refer to the element that is currently receiveing keyboard input. It doesn't mean the focus is set via a keyboard navigation. </blockquote> One of the possible workaround might be: <blockquote> You can listen to key_down events to check whether an navigation key is pressed. WPF controls do this internally to display the FocusVisualStyle. </blockquote> Is there any other, easier way to achieve what I'm trying to do? I'm not really into creating code behind, listening for events and handling all of these many different navigation keys and shortcuts.

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.
