DevExpress.Data.Filtering Namespace

Contains classes that support the data filtering feature.

Assembly: DevExpress.Data.v26.1.dll

Classes

Name	Description
AggregateOperand	An aggregate operator which calculates aggregate expressions (MIN, MAX, SUM, etc.)
BaseNodeEventArgs	The base class that provides data for a Filter Controlâ€™s events.
BetweenOperator	An operator which determines whether a criteria expression lies between the specified range of values.
BinaryOperator	A logical expression which consists of a BinaryOperatorType operation between two operands.
ConstantValue	A constant value operand in criteria expressions.
ContainsOperator	An operator which checks if a collection contains at least one object matching a specific criteria.
CriteriaCompilerAuxSettings
CriteriaOperator	Provides the abstract (MustInherit in Visual Basic) base class for criteria operators.
CriteriaOperatorCollection	Represents a collection of CriteriaOperator objects.
CustomAggregateCollection	Represents a collection to store a list of custom aggregate functions.
CustomAggregateEvaluationContext<T>	Can be used as a value type context in CreateEvaluationContext(), Process(Object, Object[]), and GetResult(Object) methods.
EnumProcessingHelper static	Provides helper methods used to register enumeration types whose values can be serialized in Criteria Language expressions.
FunctionOperator	A function operator based on a FunctionOperatorType.
GroupOperator	A logical expression which groups two or more operands with a logical AND or OR.
InOperator	An operator which determines if a value matches any value in a specified list.
JoinOperand	An operator that joins persistent objects on a specified condition, and calculates aggregate functions against matching objects.
NotOperator	Represents a logical NOT operation which is performed on the operand.
NullOperator	Represents an operator which compares a persistent objectâ€™s property value with a null reference (Nothing in Visual Basic).
OperandParameter	This class supports the internal infrastructure and is not intended to be used directly from your code.
OperandProperty	An object property operand in criteria expressions.
OperandValue	A value operand in criteria expressions.
UnaryOperator	An unary operator which performs an operation on only one expression.

Interfaces

Name	Description
IClientCriteriaVisitor	For internal use only.
ICriteriaVisitor	For internal use only.
ICustomAggregate	Declares the base functionality for custom aggregate functions.
ICustomAggregateBrowsable	Allows you to define a description of a custom aggregate function that appears in the Expression Editor, and validate the number of arguments and their type.
ICustomAggregateConvertibleToExpression	Implemented by custom aggregate functions that can be converted to a LINQ expression.
ICustomAggregateFormattable	Defines server-side processing for custom aggregate functions.
ICustomFunctionDisplayAttributes	Allows you to create a custom function displayed as a comparison operator and specify the operatorâ€™s display settings.
ICustomFunctionOperator	Declares the base functionality for custom functions.
ICustomFunctionOperatorBrowsable	Contains descriptive information about a custom function for use in the Expression editor (category, description, number of parameters).
ICustomFunctionOperatorCompileable	Implemented by custom functions that can be compiled on the client.
ICustomFunctionOperatorCompileableWithCaseSensitivity	Implemented by case-sensitive custom functions that can be compiled on the client.
ICustomFunctionOperatorConvertibleToExpression	Implemented by custom functions that can be converted to a LINQ expression.
ICustomFunctionOperatorEvaluatableWithCaseSensitivity	Implemented by custom functions that can be evaluated with case-sensitivity.
ICustomFunctionOperatorFormattable	Allows you to use the Query Builder or filter editor to insert a string into SQL queries generated for SELECT operations.

Enums

Name	Description
