Specifies a context for enabling an Action.
A SelectionDependencyType enumeration value identifying a context type.
Use this property to make the current Action dependent on whether a single object or multiple objects are selected in the current View. The following values are available:
The Action availability does not depend on the current selection.
The Action is enabled when a single object is selected.
Set the ActionBase.Category property to "RecordEdit", to display the Action in an additional cell for each object in the ASP.NET Web application's List Views.
The Action is hidden if the selection context is not available (e.g., when the Controller is not derived from ViewController).
The Action is enabled when one or more objects are selected.
By default, this property is set to Independent. Set another value if your Action is targeted for the currently selected object(s). This is definitely required if your Action takes part in a Web site UI, because it will be disabled until an object is selected.
You can set another value in the Controller's constructor or Designer. This value will be saved to the Application Model's ActionDesign | Actions | <Action> node. You can change this value in the Model Editor. In a UI, the value which is specified in the Application Model's .xafml file that was loaded last, will be displayed. For information on the order of Application Model differences loading, refer to the Application Model Basics topic.
