Declares members implemented by the UI elements that can be formatted by a conditional appearance rule.
NuGet Package: DevExpress.ExpressApp
The Conditional Appearance module allows you format (highlight) different UI elements when they are displayed under certain conditions. To allow the AppearanceController to format UI elements, they should implement the IAppearanceFormat interface. This interface exposes the IAppearanceFormat.BackColor, IAppearanceFormat.FontColor and IAppearanceFormat.FontStyle properties, to get or set the appearance format, and the IAppearanceFormat.ResetBackColor, IAppearanceFormat.ResetFontColor and IAppearanceFormat.ResetFontStyle methods, to reset the appearance format to the required initial value.
This interface is already implemented by base classes representing built-in XAF Detail View Items, Layout Items and auxiliary adapters that provide access to List Editor cells. Implement the IAppearanceFormat interface in a custom class representing a UI element so that this element can also be formatted by the AppearanceController.
