DirectX Styles are defined as features of a Visual Style. They can be thought of as much the same as cascading style sheet, with multiple styles defined in one place.
The following example shows a few basic styles:
Unlike Visual Styles, DirectX Styles only affect the features specifically referenced in their definition.
DirectX Styles are made up of background and foreground features. Only the foreground features - TextColor, Font and ForegroundBrush - are adopted by child controls. This is because borders and a background brush applied to a panel are usually not required on child controls. Instead, panels and labels are transparent by default, allowing a base background to be visible. If you want the background and border to repeat on each control, you can explicitly apply the Style.
