IAppearanceEnabled Interface
Declares members implemented by the UI elements that can be disabled or enabled by a conditional appearance rule.
Namespace: DevExpress.ExpressApp.Editors
Assembly: DevExpress.ExpressApp.v19.2.dll
Declaration
Remarks
The Conditional Appearance module allows you to enable/disable specific UI elements when they are displayed under certain conditions. To allow the AppearanceController to disable/enable UI elements, they should implement the IAppearanceEnabled interface. This interface exposes the IAppearanceEnabled.Enabled property, to get or set the enabled state, and the IAppearanceEnabled.ResetEnabled method, to reset the enabled state to the required initial value.
This interface is already implemented by base classes representing built-in XAF Detail View Items, Layout Items, Action Appearance Items and auxiliary adapters that provide access to List Editor cells. Implement the IAppearanceEnabled interface in a custom class representing a UI element so that this element can also be disabled/enabled by the AppearanceController.
