TreeListEditor Class

List Editors are used by List Views to display object collections in a UI. The TreeListEditor is implemented in the TreeList Editors module, and displays data in the form of a tree:

To display object collections, the TreeListEditor uses an instance of the ObjectTreeList as the underlying control. The ObjectTreeList is a descendant of the TreeList class.

The TreeListEditor supports a range of features out of the box:

• Implements the ISupportAppearanceCustomization interface - supports conditional appearance:

  

• Implements the IExportable interface - can be exported via the ExportController and printed via the PrintingController:

  

  

• Implements the IDXPopupMenuHolder interface, and provides an ActionDX pop-up menu:

  

• Implements the IControlOrderProvider interface - supports the RecordsNavigationController's PreviousObject and NextObject Actions:

  

Since it is not possible to represent an arbitrary object collection in the form of a tree, the objects that will be displayed via the TreeListEditor must implement the ITreeNode interface. To learn how to implement this interface, refer to the Display a Tree List using the ITreeNode Interface topic.
