The following members accept/return RepositoryItemTreeListLookUpEdit objects:


The RepositoryItemTreeListLookUpEdit class provides properties, methods and events for Tree List Lookup Edit controls (the TreeListLookUpEdit class objects). You can access these settings through the editor’s TreeListLookUpEdit.Properties object. See the TreeListLookUpEdit topic to learn more.

You do not need to create repository items manually unless you have to create inplace editors for container controls (such as the XtraGrid).


The TreeListLookUpEdit control does not have a connection to an underlying data source while the editor’s dropdown window is closed. For that reason, you can use methods provided by the embedded Tree List to access the underlying data or TreeList‘s calculated data only when the control’s dropdown window is open.

While the dropdown window is closed, you can access the underlying data using methods provided by the underlying data source.


The TreeList control embedded in the TreeListLookUpEdit editor does not support the unbound mode.
