I am working on a WP7 app using Location Services and Bing Maps. I would like the Bing Maps control to rotate to always have the current heading at the top. I understand this isn't possible with the Bing Maps Control, so I'm trying to use a Rotation Transform to rotate the entire control. I'm using the LayoutTransformerOnWindowsPhone assembly found here: <a href="http://blogs.msdn.com/b/delay/archive/2010/08/26/your-phone-can-turn-into-a-robot-layouttransformer-works-great-on-the-windows-phone-platform.aspx" rel="nofollow">http://blogs.msdn.com/b/delay/archive/2010/08/26/your-phone-can-turn-into-a-robot-layouttransformer-works-great-on-the-windows-phone-platform.aspx</a> When the page loads, the control gets rotated to the correct heading, but it doesn't keep rotating as the heading changes. Here's my code: Xaml: <pre><code><Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> <toolkit:LayoutTransformer> <toolkit:LayoutTransformer.LayoutTransform> <RotateTransform x:Name="mapRotation" /> </toolkit:LayoutTransformer.LayoutTransform> <my:Map Name="map1" Margin="0,0,0,0" CredentialsProvider="xyz"/> </toolkit:LayoutTransformer> </Grid> </code></pre> cs: <pre><code>if (Compass.IsSupported) { _compass = new Compass {TimeBetweenUpdates = TimeSpan.FromMilliseconds(500)}; _compass.CurrentValueChanged += new EventHandler<SensorReadingEventArgs<CompassReading>>(compass_CurrentValueChanged); _compass.Start(); } void compass_ValueChanged(object sender, SensorReadingEventArgs<CompassReading> e) { Dispatcher.BeginInvoke(() => UpdateUI(e.SensorReading)); } private void UpdateUI(CompassReading compassReading) { _currentHeading = compassReading.TrueHeading; mapRotation.Angle = _currentHeading; } </code></pre>

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.
