Thanks for your answers! I looked into this issue myself a bit futher and came up with the following solution (which I'm not entirely satisfied with, but it works fine) I've created a CustomControl that adds functionality to the TextBox. It provided an event handler for the LostFocus event When this event occurs, my converter is called. However, the way I resolve the Converter is not very satisfying (I take it from the Style that is associated with my TextBox). The Style has a Setter for the Text property. From that setter I can access my Converter. Of course I could also make a "PlusTextBox", but I use different converters and I wanted a generic solution. <pre><code>public class TextBoxEx : TextBox { public TextBoxEx() { AddHandler(LostFocusEvent, new RoutedEventHandler(CallConverter), true); } public Type SourceType { get { return (Type)GetValue(SourceTypeProperty); } set { SetValue(SourceTypeProperty, value); } } // Using a DependencyProperty as the backing store for SourceType. This enables animation, styling, binding, etc... public static readonly DependencyProperty SourceTypeProperty = DependencyProperty.Register("SourceType", typeof(Type), typeof(TextBoxEx), new UIPropertyMetadata(null)); private static void CallConverter(object sender, RoutedEventArgs e) { TextBoxEx textBoxEx = sender as TextBoxEx; if (textBoxEx.Style == null) { return; } if (textBoxEx.SourceType == null) { } foreach (Setter setter in textBoxEx.Style.Setters) { if (setter.Property.ToString() == "Text") { if (! (setter.Value is Binding) ) { return; } Binding binding = setter.Value as Binding; if (binding.Converter == null) { return; } object value = binding.Converter.ConvertBack(textBoxEx.Text, textBoxEx.SourceType, binding.ConverterParameter, System.Globalization.CultureInfo.CurrentCulture); value = binding.Converter.Convert(value, typeof(string), binding.ConverterParameter, System.Globalization.CultureInfo.CurrentCulture); if (!(value is string)) { return; } textBoxEx.Text = (string)value; } } } } </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.
