The type of the UI element whose appearance is about to be refreshed by applying conditional appearance rules.
A string that is the type of the target UI element whose conditional appearance is refreshed.
The Conditional Appearance module allows you to apply a conditional appearance to different UI elements. They are differentiated by the following appearance item types:
|Cells in the List View represented by a GridListEditor, ASPxGridListEditor, TreeListEditor or ASPxTreeListEditor||AppearanceItemType.ViewItem|
|Layout Items, Groups and Tabs||AppearanceItemType.LayoutItem|
The ItemType property specifies a sting representation of one of these appearance item types.
If you apply a conditional appearance rule to an item of a custom type, there should be a custom Controller that invokes the AppearanceController.RefreshItemAppearance method when required. In this instance, the custom item type is passed to the Appearance Controller and you get it as a value of the ItemType property when handling the AppearanceController.CustomApplyAppearance or AppearanceController.AppearanceApplied event.
