Unbound Columns Overview
Unbound columns are not bound to any field in a data source. These columns must be populated manually via the ASPxGridView.CustomUnboundColumnData event.
An unbound column meets the following requirements.
- Its GridViewDataColumn.FieldName property must be set to a unique value and not refer to any field in ASPxGridView‘s data source.
- The column’s GridViewDataColumn.UnboundType property must be set to an appropriate value based on the type of data the column is supposed to display (Boolean, DataTime, Decimal, Integer, String, Object). It shouldn’t be set to UnboundColumnType.Bound.
Limitations
- The grid cannot sort or group unbound columns whose GridViewDataColumn.UnboundType property is set to Object.
