Remarks

You can create an unbound column by setting the TreeListDataColumn.UnboundType property to a specific data type. Unbound columns can be populated manually via the ASPxTreeList.CustomUnboundColumnData event, or by specifying an expression via the UnboundExpression used to evaluate values for this field. The Expressions section describes the syntax for creating expressions.
