I'm trying to create a special button that colors an image based on Foreground color from the system. The solution seems to be in using the image as opacity mask to get the color and it works when I set the image directly like this: <pre><code><Grid> <Rectangle x:Name="ImageForeground" Height="48" Width="48" Fill="{StaticResource PhoneForegroundBrush}" > <Rectangle.OpacityMask> <ImageBrush Stretch="Fill" ImageSource="/icons/play.png"/> </Rectangle.OpacityMask> </Rectangle> </Grid> </code></pre> But as soon as I try template this with a DependencyProperty for the image lite this: <pre><code>public static readonly DependencyProperty ImageProperty = DependencyProperty.Register("Image", typeof(ImageSource), typeof(RButton), null); </code></pre> And then in the XAML like this: <pre><code><Grid> <Rectangle x:Name="ImageForeground" Height="48" Width="48" Fill="{TemplateBinding Foreground}" > <Rectangle.OpacityMask> <ImageBrush Stretch="Fill" ImageSource="{TemplateBinding Image}"/> </Rectangle.OpacityMask> </Rectangle> </Grid> </code></pre> I get an error saying: <pre><code>object of type 'System.Windows.CustomDependencyProperty' cannot be converted to type 'System.Windows.DependencyProperty' </code></pre> The ImageProperty is ok, as I tested binding it to an image instead like this <pre><code><Image Source="{TemplateBinding Image}" Width="48" Height="48" /> </code></pre> Any ideas? My hunch says its in how I define my DependecyProperty, but I don't know how to move forward.

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.
