Remarks

The Tree List control stores its columns in the TreeList.Columns collection. This collection is represented by the TreeListColumnCollection class. Members of this class can be used to add, delete, access individual column objects and perform other common collection management tasks. Individual columns stored within such collections are represented by TreeListColumn objects. Note that you don’t have to create such objects manually. They are automatically created by the collection’s TreeListColumnCollection.Add and TreeListColumnCollection.Insert methods. You can also fill the collection with columns created for each data field within the Tree List’s associated data source using the TreeList.PopulateColumns method.
