The events OnItemDeleted, OnItemCreated and OnItemRenamed are not used in Telerik.FileManager.ManageFiles
control. The control does not expose events that you could use to track the files changes. ManageFiles wraps another control - FilesGrid where OnFolderStructureChanged event is called for Delete, Rename and Create operations. The event is used only to notify the RadGrid to rebind.
Your task requires a custom module or a new backend section.
