    <p>I think you are binding to the SeatState object - whereas you actually need to bind to some combination of the <code>Occupied</code> an <code>Locked</code> properties?</p> <p>i.e. it's not the SeatState object itself that is changing, but rather its a couple of the properties of the SeatState. </p> <p>Maybe merge the properties together somehow and set this merged property as the Path for the XAML Background. </p> <p>e.g. within SeatState</p> <pre><code>private bool _Locked public bool Locked { get { return _Locked; } set { _Locked = value; NotifyPropertyChange("Locked"); NotifyPropertyChange("LockedAndOccupied"); } } private bool _Occupied public bool Occupied { get { return _Occupied; } set { _Occupied = value; NotifyPropertyChange("Occupied"); NotifyPropertyChange("LockedAndOccupied"); } } public Tuple&lt;bool, bool&gt; LockedAndOccupied { get { return new Tuple&lt;bool, bool&gt;(Locked, Occupied); } } </code></pre> <p>then in the XAML you can bind to <code>Path=LockedAndOccupied, Converter=...</code></p> <p>Obviously you'll have to change the Converter code too - I'll let you do that!</p> <hr> <p>Alternatively... now I've read up about it...</p> <p>There is something called a MultiBinding - <a href="http://www.switchonthecode.com/tutorials/wpf-tutorial-using-multibindings" rel="nofollow">http://www.switchonthecode.com/tutorials/wpf-tutorial-using-multibindings</a> - looks perfect for your needs</p> <p>Something like:</p> <pre><code>&lt;Border.Background&gt; &lt;MultiBinding Converter="{StaticResource aNewConverter}"&gt; &lt;Binding Path="Locked"/&gt; &lt;Binding Path="Occupied"/&gt; &lt;/MultiBinding&gt; &lt;/Border.Background&gt; </code></pre> <p>I've learnt something new tonight :)</p>

    1. COI need the two properties, and the converter recives the object just fine, so it really shouldn't have anything to say, right?

    2. CObut if you bind to the object, then it's only when the reference to the object itself changes that the binding updates.

    3. COohhh, i think i see what you mean. The one problem i'm facing now is that the entity is generated by entity framework 4.0 So i would prefer not to edit the entity 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.
