AggregateOperand Class

The operator that calculates an aggregate expression (MIN, MAX, SUM, etc.).

Namespace: DevExpress.Data.Filtering

Assembly: DevExpress.XamarinForms.Core.dll

Declaration

[Serializable]
public class AggregateOperand :
    CriteriaOperator

Remarks

You can use the AggregateOperand operand to compose criteria which are based on the collection properties to filter the collection. It represents the results of aggregate operations performed on these types of properties.

Note
  • AggregateOperand.AggregatedExpression must specify a path through object relationships (Sum([Income]) or Sum([Cargo.Price])), and does not support nested expressions and complex property paths like Max(Document.<PersonID>LastName).
  • AggregatedExpression may produce null instead of zero for an empty collection on a server side.
