<p>This should work fine with a simple DataTrigger.</p> <p>Your Object Class:</p> <pre><code>public class TestObject { public string Name { get; set; } public bool IsHighlighted { get; set; } public override string ToString() { return this.Name; } } </code></pre> <p>Xaml:</p> <pre><code><Window x:Class="TestWPF.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestWPF" Title="MainWindow"> <Grid> <StackPanel> <ComboBox> <ComboBox.Resources> <Style TargetType="ComboBoxItem"> <Setter Property="FocusVisualStyle" Value="{x:Null}" /> <Setter Property="Background" Value="Gray" /> <Style.Triggers> <DataTrigger Binding="{Binding IsHighlighted}" Value="True"> <Setter Property="Background" Value="Red" /> </DataTrigger> </Style.Triggers> </Style> </ComboBox.Resources> <local:Employee Name="Nick" /> <local:Employee Name="Bob" IsHighlighted="True" /> <local:Employee Name="Fred" /> </ComboBox> </StackPanel> </Grid> </Window> </code></pre> <p>Note: Unlike the sample above, I'm guessing in your code you're binding the combobox's ItemsSource... which should work just the same. One thing to be careful of though, is if your object's 'IsHighlighted' property can change, you should be implementing INotifyProperty changed to ensure that changing the value will notify the UI that the triggers should refresh.</p>

Guidance

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.
