Specifies a context for enabling an Action.

Namespace: DevExpress.ExpressApp.Actions

Assembly: DevExpress.ExpressApp.v23.1.dll

NuGet Package: DevExpress.ExpressApp


public SelectionDependencyType SelectionDependencyType { get; set; }

Property Value

Type Default Description
SelectionDependencyType Independent

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.

If the SelectionDependencyType property is set to RequireSingleObject, you can set the ActionBase.Category property to “RecordEdit”, to display the Action in an additional cell for each object in the ASP.NET Web Forms application’s List Views.


The Action is hidden if the selection context is not available (for example, when the Controller is not derived from ViewController).

You can set another value in the Controller’s constructor or Designer. This value is 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.
