The Columns property defines the number of columns.

The number of columns can only be changed if a tree control is empty. The Items.Clear method can be used to remove all items from a tree control.

Additional columns are always added at the end of the list of columns. Existing column properties are not changed. Default values are used for the new columns added. These can be changed using the column related properties. The last column will be defined using an explicit column width. If an open-ended column is desired, use the ColumnsObj.OpenEnded property to redefine the last column.
