Event Data

The CustomUnboundColumnData event's data class is TreeListUnboundColumnDataEventArgs. The following properties provide information specific to this event:

Property Description
Column Gets the unbound column currently being processed. Inherited from ColumnDataEventArgsBase.

Unbound columns are not bound to any field in a data source. In most instances, data for unbound columns is obtained from a custom data source or is calculated based upon the values of bound columns. To provide data for unbound columns, and save any changes made back to a custom data source, handle the CustomUnboundColumnData event.
