Syntax

public class FilterExpression : CompositeFilterDescriptor, INotifyPropertyChanged, INotifyPropertyChangingEx, ICloneable

Constructors

FilterExpression()

Creates an instance of the FilterExpression class.

Declaration

public FilterExpression()

FilterExpression(String)

Creates an instance of the FilterExpression class.

Declaration

public FilterExpression(string fieldName)

Parameters

System.String fieldName The field name in the context of which the filter string is generated.

FilterExpression(String, FilterExpression.BinaryOperation, GridKnownFunction, Object[])

Creates an instance of the FilterExpression class with a new FilterPredicate.

Declaration

public FilterExpression(string fieldName, FilterExpression.BinaryOperation binaryOperation, GridKnownFunction function, params object[] values)

Parameters

System.String fieldName The field name in the context of which the filter string is generated.

FilterExpression.BinaryOperation binaryOperation The binary operation that is used by the new FilterExpression.

GridKnownFunction function The GridKnownFunction that is used to create the FilterPredicate object.

System.Object[] values The values that are used to create the FilterPredicate object.

FilterExpression(FilterExpression.BinaryOperation, GridKnownFunction, Object[])

Creates an instance of the FilterExpression class with a new FilterPredicate.

Declaration

public FilterExpression(FilterExpression.BinaryOperation binaryOperation, GridKnownFunction function, params object[] values)

Parameters

FilterExpression.BinaryOperation binaryOperation The binary operation that is used by the new FilterExpression.

GridKnownFunction function The GridKnownFunction that is used to create the FilterPredicate object.

System.Object[] values The values that are used to create the FilterPredicate object.
