    <p>How can I transfer the Source attribute from a button template to an Image inside that template ?</p> <p>This is how my XAML looks like:</p> <pre><code>&lt;Page x:Class="TallShip.MainGallery" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:TallShip" mc:Ignorable="d" d:DesignHeight="1080" d:DesignWidth="1920" Title="MainGallery"&gt; &lt;Grid&gt; &lt;ScrollViewer Height="958" HorizontalAlignment="Left" Margin="685,87,0,0" Name="GalleryRightScroller" VerticalAlignment="Top" Width="1159" PanningMode="VerticalOnly" VerticalScrollBarVisibility="Auto"&gt; &lt;Grid&gt; &lt;Grid.Resources&gt; &lt;ControlTemplate x:Key="GalleryObject"&gt; &lt;StackPanel Height="Auto" HorizontalAlignment="Left" Margin="{TemplateBinding Margin}" VerticalAlignment="Top" Width="500"&gt; &lt;Image Height="200" Stretch="None" Source="{TemplateBinding local:SourceHolder.Source}" Width="200" /&gt; &lt;Label Content="{TemplateBinding local:SourceHolder.Source}" Height="28" Name="label1" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" /&gt; &lt;/StackPanel&gt; &lt;/ControlTemplate&gt; &lt;/Grid.Resources&gt; &lt;Button Template="{StaticResource GalleryObject}" local:SourceHolder.Source="/TallShip;component/media/91gx2EQ.jpg" Name="object1" Margin="43,21,0,0"/&gt; &lt;Button Template="{StaticResource GalleryObject}" local:SourceHolder.Source="/TallShip;component/media/91gx2EQ.jpg" Name="object2" Margin="43,280,0,0"/&gt; &lt;/Grid&gt; &lt;/ScrollViewer&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>And this is the custom control class I've created to hold the Source property:</p> <pre><code>namespace TallShip { public static class SourceHolder { public static readonly DependencyProperty SourceProperty = DependencyProperty.RegisterAttached("Source", typeof(string), typeof(SourceHolder), new FrameworkPropertyMetadata(null)); public static string GetSource(UIElement element) { if (element == null) throw new ArgumentNullException("element"); return (string)element.GetValue(SourceProperty); } public static void SetSource(UIElement element, string value) { if (element == null) throw new ArgumentNullException("element"); element.SetValue(SourceProperty, value); } } } </code></pre> <p>Currently, the label correctly displays the passed source, but the image does not work...</p> <p>If I use the same source on an image outside of the button template, the image works just fine.</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.
