Collection Properties
- 2 minutes to read
XAF applications display collection properties in nested List Views. Different collection properties have different Actions in a UI.

Refer to the following topics for information on relationships between entities in code and UI:
- Relationships Between Persistent Objects in Code and UI (XPO)

Property Editors for Collection Properties
XAF applications use the UI-independent ListPropertyEditor. It creates a Template and Frame that contains a List View. This List View uses the ListView.CollectionSource of the PropertyCollectionSource type. For more information on Templates, Frames, and Views, refer to the UI Element Overview topic.
In the Model Editor, set the IModelMemberViewItem.View property to a custom List View to use this View instead of the default one. You can also manage the New, Delete, Link, or Unlink Action’s visibility in the Model Editor. Set the List View’s AllowNew, AllowDelete, AllowLink, or AllowUnlink property to false to hide these Actions.
