Accessing Columns

The ASPxTreeList control stores its columns within the ASPxTreeList.Columns collection. To access only visible columns, use the ASPxTreeList.VisibleColumns property. Individual columns are represented by the TreeListDataColumn objects. A data column can be accessed by specifying its ID, caption or the name of the data source field to which it is bound.

On the client, data columns can be accessed via the methods listed below:

The number of columns can be obtained via the ASPxClientTreeList.GetColumnCount method.
