Property Value

Type	Description
SelectionType	A SelectionType enumeration value that represents the selection type supported by the current List Editor.

Available values:

Name	Description
None	A List Editor or a View does not support focusing an object nor selection of objects.
FocusedObject	A List Editor or a View supports focusing an object, but does not support selection of objects.
MultipleSelection	A List Editor or a View supports selection of single and multiple objects.
TemporarySelection	A List Editor or a View supports selection type, which is active only while a postback is processed. For instance, it can be active when a record displayed by an ASP.NET Web Forms List editor is clicked.
Full	A List Editor or a View supports selection of single and multiple objects, as well as focusing an object.

Remarks

The ASPxTreeListEditor supports selection of a single object as well as selection of multiple objects. So, the SelectionType property always returns SelectionType.MultipleSelection.

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.
