    <p>The converter is applied to the property that stores the collection. Therefore, it will only be called if the collection instance itself changes (not if items in the collection are changed). One way around this would be to invalidate the collection when you want it to refresh.</p> <p>The simplest way to invalidate the collection property and cause the converter code to run again would be to <code>null</code> out the collection and reassign it. Another way is to get the <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.bindingexpression.aspx" rel="nofollow noreferrer"><code>BindingExpression</code></a> (via <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.bindingoperations.aspx" rel="nofollow noreferrer"><code>BindingOperations</code></a>) and call <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.bindingexpression.updatetarget.aspx" rel="nofollow noreferrer"><code>UpdateTarget</code></a>. Finally, you could instead bind to a <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.collectionview.aspx" rel="nofollow noreferrer"><code>CollectionView</code></a> (or subclass thereof) and call <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.collectionview.refresh.aspx" rel="nofollow noreferrer"><code>Refresh</code></a> on it.</p> <p>And if you <em>really</em> want to fix the problem cleanly, you could bind to your own implementation of <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.icollectionview.aspx" rel="nofollow noreferrer"><code>ICollectionView</code></a> which does the filtering and raises events as necessary.</p>

    1. COI think understand what your telling me to do, but I'm not sure how to do that with the hierarcicalDataTemplate. If I understand correctly, I want to wrap the People Property in a CollectionView, and refresh the CollectionView when the Collection changes. Some example code would be a big help.

    2. COThanks for the help, I got it working by wrapping my people list in an ObservableCollection of projects that subscribed to the people collection changed event and updated itself.

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.
