    <p>My WP7 app has an Image control whose Source is set in XAML to an image with its Build Action set to Content:</p> <pre><code>&lt;Image x:Name="MyImage" Source="/Images/myimage.png"/&gt; </code></pre> <p>I need to store this image in my SqlCe database as a byte array. This is my current code to convert to byte[]:</p> <pre><code>public byte[] ImageToArray() { BitmapImage image = new BitmapImage(); image.CreateOptions = BitmapCreateOptions.None; image.UriSource = new Uri( "/Images/myimage.png", UriKind.Relative ); WriteableBitmap wbmp = new WriteableBitmap( image ); return wbmp.ToArray(); } </code></pre> <p>The byte array saves to the database, but when I retrieve and my converter tries to convert it back (on a different page), I get "unspecified error." This is my converter:</p> <pre><code>public class BytesToImageConverter : IValueConverter { public object Convert( object Value, Type TargetType, object Parameter, CultureInfo Culture ) { if( Value != null &amp;&amp; Value is byte[] ) { byte[] bytes = Value as byte[]; using( MemoryStream stream = new MemoryStream( bytes ) ) { stream.Seek( 0, SeekOrigin.Begin ); BitmapImage image = new BitmapImage(); image.SetSource( stream ); // Unspecified error here return image; } } return null; } public object ConvertBack( object Value, Type TargetType, object Parameter, CultureInfo Culture ) { throw new NotImplementedException( "This converter only works for one way binding." ); } } </code></pre> <p>I've done quite a bit of searching. As far as the converter, my code is pretty standard. I've seen mention that <code>stream.Position = 0;</code> is necessary, but my understanding is <code>stream.Seek</code> is doing the same thing; I've tried both.</p> <p>As my converter is the same I've used in about a dozen projects now, I'm fairly convinced the problem lies in converting the Image control's Source to a byte array and thus my image data is corrupted. In the code above I'm hard coding the Uri, but I've also tried</p> <pre><code>BitmapImage image = MyImage.Source as BitmapImage; </code></pre> <p>without luck. I've been at this for hours and at my wit's end. What am I missing?</p>

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.
