Specifies whether an Action is represented by an accept, cancel or ordinal button in a Window Forms application's pop-up Windows.
This property is considered for Actions that are displayed in pop-up Windows in Windows Forms applications. The following values are available:
The Action is executed when an end-user presses ENTER.
The Action is executed when an end-user presses ESC.
The Action is executed when an end-user clicks it or uses a predefined shortcut.
You can add an Action to a pop-up Window. For this purpose, set its ActionBase.Category property to the "ObjectsCreation" or "PopupActions" value. This, means that the Action will be mapped to the ObjectsCreation or PopupActions Action Container. So, the Action will be displayed in pop-up Windows which are represented by the LookupControlTemplate or PopupForm Template, because the former contains both these Action Containers and the former - the "PopupActions" Action Container.
You can process the ActionMeaning property in a custom Action Container. In this instance, do not forget to add this Container to a built-in Template or a custom one (see How to: Create a Custom WinForms Ribbon Template).
