ChoiceActionBase Class

Represents the ancestor for Actions that provide items to be chosen by an end-user.

Namespace:DevExpress.ExpressApp.Actions
Assembly:DevExpress.ExpressApp.v19.1.dll

Expanded Syntax

Expanded Remarks

Currently, the ChoiceActionBase class has a single descendant - the SingleChoiceAction. This descendant allows end-users to select a single item in the Items collection. This collection is provided by the ChoiceActionBase class. Each collection item can have child items as well. So, you can form a tree within this collection.

You can specify how to display a Choice Action, if its Items collection is empty. For instance, this Action can be disabled or made invisible (see EmptyItemsBehavior).

You can specify whether to execute a Choice Action when clicking it, or show its drop-down with items (see ShowItemsOnClick). To specify the Choice Action Item that is executed by default, use the DefaultItemMode property. You can set whether to always execute the first active item in Items collection or to execute the previously executed item.
