This property is used by XAF to determine what Actions to enable for a List View. Each Action has the ActionBase.SelectionDependencyType property that specifies whether an Action’s availability depends on the current selection. XAF determines what actions to enable for a List View by comparing the value of the Action’s SelectionDependencyType property with the List Editor‘s SelectionType property value. For instance, if an Action requires a selected object and the current List Editor does not support selection, the Action will not be available.
