Remarks

The DXGrid 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. The Expressions section describes the syntax for creating expressions.
