public event UnboundValueEventHandler GetUnboundValue

[C1Description("Fires when the grid needs to retrieve data for an unbound cell.")]
public:
event UnboundValueEventHandler^ GetUnboundValue

This event fires in bound mode when the grid contains unbound columns. Unbound columns are columns that have the Name property set to values that do not map to columns in the data source. The information in unbound columns must be provided by the application, by setting the Value property of the UnboundValueEventHandler parameter.

The System.Data.DataTable class supports calculated columns that in many situations can be used instead of unbound columns.
