AggregateDisplay Enumeration |
Options specifying how the mapper should display aggregate data. This is specified using the
mapper "AggregateDisplay" property. Note that displaying aggregate data requires an additional
query which may have a performance impact on the application. If so desired, he developer can
use the persistence options to reduce this impact by making sure that users don't turn on
aggregate display permanently.
When aggregates are enabled you can specify the type of aggregation to use on each field by setting its AggregateType. Unless ExplicitFieldsOnly is specified, fields without an explicit AggregateType setting will default to an aggregation based primarily on the field's OleDbType and CellType and whether or not it has a Picklist. Typically the only non-None default is to use Sum for numeric fields.
When aggregates are enabled on a datasheet with grouping applied aggregates, in addition to ovreal aggregates, aggregates will be displayed for each grouping .
