Unbound Columns
ASPxCardView supports both bound and unbound columns. Bound columns obtain data from the control’s data source. Unbound columns are not bound to any field in a data source. To populate an unbound column manually, handle the ASPxCardView.CustomUnboundColumnData event or use the CardViewColumn.UnboundExpression property to specify an expression for the column. The following help topic section describes the syntax used to create expressions: Expressions.
Bound and unbound columns provide similar functionality. You can sort and filter unbound columns in the same manner as bound columns.
