ConstantValue Class

A constant value operand in Criteria Language expressions.

Namespace: DevExpress.Data.Filtering

Assembly: DevExpress.XamarinForms.Core.dll


public class ConstantValue :


Criteria language processor automatically passes value operands (OperandValue objects) to resulting queries as default parameters when processing criteria expressions. Replace OperandValue with ConstantValue to embed in-line parameters into queries. This change improves performance when a data processor executes several queries that match values with constants passed as parameters.
