Remarks

Specific data-aware controls (such as the XtraGrid) support bound and unbound columns. Bound columns obtain their data automatically from the control’s underlying data source. The data for unbound columns should be provided manually by handling the appropriate event.

Each column in these controls provides a specific property of the UnboundColumnType type and this specifies the column’s data type and binding mode.
