Body
I want to set an image's source according to its <code>DataContext</code> in a <code>ChildWindow</code>. Here is the XAML file: <pre><code><controls:ChildWindow x:Class="CEM.Controls.DialogWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" Title="{Binding Title}"> ... <Image x:Name="DialogIcon"></Image> ... </controls:ChildWindow> </code></pre> It's working fine if I override the <code>Show</code> method of the <code>ChildWindow</code> and set the image's source: <pre><code>public new void Show() { DialogIcon.Source = new BitmapImage(new Uri(@"/Images/DialogWindow/Confirm.png", UriKind.Relative)); base.Show(); } </code></pre> But it looks ugly and it's not the "silverlight way", so I decide to change: <pre><code><Image x:Name="DialogIcon" Source="{Binding DialogIconType, Converter={StaticResource DialogIconConverter}}"></Image> </code></pre> You see I have a <code>DialogIconConverter</code> registered to bind the source from the <code>DataContext</code>. <pre><code>public class DialogIconConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { //currently it's an hard-coded path return new BitmapImage(new Uri(@"/Images/DialogWindow/Confirm.png", UriKind.Relative)); } ... } </code></pre> But it's not working now, I have several other converters in this control which are working fine. Only this one is not working. Can you help to find where the problem is? EDIT: <code>DialogIconType</code> is an enum, and also it's a property of <code>DialogContext</code>. An instance of <code>DialogContext</code> will be assigned to <code>DataContext</code> property of the <code>DialogWindow</code>. <pre><code>public enum DialogIconType { Confirm, Alert, Error } public class DialogContext { public string Title { get; set; } public string Content { get; set; } public DialogButtons Buttons { get; set; } public DialogIconType IconType { get; set; } } internal DialogWindow(DialogContext context) { InitializeComponent(); this.DataContext = context; } </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.
