Remarks

The Grid Control supports bound and unbound columns. Bound columns obtain their data from data fields in a grid’s data source. Unbound columns are not bound to any field in the data source. These columns must be populated manually by handling the GridControl.CustomUnboundColumnData event or using the UnboundExpression property.
