title: Bold and Italic text depending on data in WPF ComboBox, without XAML
body: <p>I have a CustomControl that is derived from ComboBox and I would like to show certain items with Bold text, some with Italic and some normal, depending on associated data.  Since there's no XAML associated with this, I am having trouble finding a way to handle this.  The items are DataBound to the control via the ItemsSource property so each item type is just the Object type for my data object.</p>
  
  <p>Any ideas?</p>
