__property bool Active = {read=FActive, write=SetActive, default=0};
Description
Indicates whether the aggregate should be calculated.
Use the Active property to indicate that the aggregate field's value should be maintained when possible. If Active is false, the value of the aggregate is never calculated.
If Active is true, the aggregate field's value is calculated unless
It summarizes records over a group not defined by the current index.
The client dataset's AggregatesActive property is false.
Note: To determine whether the aggregate that corresponds to the field is currently maintained, read its InUse property.
