    <p>My search contract basically looks at an SQLite database, and returns the relevant records. These records are then manipulated so that the appropriate information is available for display and selection on the search charm page. However, I a results corresponding image to display with the result (following the default search contract result template)</p> <p>The image is stored as a string in my <code>CustomObjectRecord</code> database. When the record is selected it is converted to a <code>CustomObject</code>, and the image string saved in the <code>CustomObjectRecord</code> is converted to a Bitmap object called <code>searchImage</code>. I want this to be displayed with my results, but when the search charm returns I get an error on the output console</p> <p><code>Error: BindingExpression path error: 'searchImage' property not found on 'My_App.Classes.CustomObject, My App, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. BindingExpression: Path='searchImage' DataItem='My_App.Classes.CustomObject, My App, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'; target element is 'Windows.UI.Xaml.Controls.Image' (Name='thumbImage'); target property is 'Source' (type 'ImageSource')</code></p> <p>The template definition</p> <pre><code>&lt;DataTemplate x:Key="LocalStandardSmallIcon300x70ItemTemplate"&gt; &lt;Grid Width="294" Margin="6"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="Auto"/&gt; &lt;ColumnDefinition Width="*"/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" Margin="0,0,0,10" Width="40" Height="40"&gt; &lt;Image Name="thumbImage" Source="{Binding searchImage}" Stretch="UniformToFill"/&gt; &lt;/Border&gt; &lt;StackPanel Grid.Column="1" Margin="10,-10,0,0"&gt; &lt;TextBlock Text="{Binding Name}" Style="{StaticResource BodyTextStyle}" TextWrapping="NoWrap"/&gt; &lt;/StackPanel&gt; &lt;/Grid&gt; &lt;/DataTemplate&gt; </code></pre> <p><code>searchImage</code> is defined in CustomObject as</p> <pre><code> public Bitmap searchImage; </code></pre> <p>The <code>searchImage</code> property of my CustomObject is set when the record is loaded from the database. The Name binding in the same template works fine.</p> <p>Any pointers would be great. If any more code is required please let me know.</p>

    1. COthe message seems to indicate the property is not there at all versus having an issue with formats, etc. Is the name "searchImage" supposed to be camel case? e.g., if you changed searchImage to Name here (invalid, I know) would you get that same error?

    2. COsearchImage is defined in CustomObject as I've added above. I tried putting in Name instead of searchImage in the binding and the error does not show up, though obviously the image is still blank grey. I don't understand why the image is not seen in searchImage when Name is, as they are both defined in the same place.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
