Remarks

This property determines whether the TreeList.PopulateColumns method is called automatically when a data source is assigned to the Tree List which doesn’t contain any columns. The TreeList.PopulateColumns method creates TreeListColumn objects for all the fields in the underlying data source and make these columns visible.

Set the AutoPopulateColumns property to false to prevent columns from being automatically created. In this case columns should be manually added to the TreeList.Columns collection.
