Property Value

Type	Description
String	A string that specifies the type of the target UI element when you apply conditional appearance rules.

Remarks

The Conditional Appearance module applies conditional appearance rules to different UI elements. You identify these elements by their appearance item types.

UI Element	AppearanceItemType
**Cells in the List View that a GridListEditor or TreeListEditor displays.	AppearanceItemType.ViewItem
Property Editors	AppearanceItemType.ViewItem
Static Text	AppearanceItemType.ViewItem
Layout Items, Groups, and Tabs	AppearanceItemType.LayoutItem
Actions	AppearanceItemType.Action

The ItemType property returns a string that specifies the type of the target UI element.

If you apply a conditional appearance rule to an item with a custom type, you need a custom Controller. The Controller calls the AppearanceController.RefreshItemAppearance method when needed. The custom Controller passes the custom item type to the Appearance Controller. You receive the value in the ItemType property when you handle the AppearanceController.CustomApplyAppearance or AppearanceController.AppearanceApplied event.
