Now I keep some specific data in TElXTreeItem.Data as pointer to some object and OnItemDeletion I can cast it and delete this object. Now I need to store some header column specific data and I found TElHeaderSection.Data property but I can't find event like eg. OnHeaderSectionDeletion where I can delete object attached to this property.
