Properties

CultureInfo

Gets or sets the culture of the filter descriptor.

public CultureInfo CultureInfo { get; set; }

Property Value:

The culture of the filter descriptor.

IsActive

public abstract bool IsActive { get; }

Property Value:

A value indicating whether this filter is active.

IsCaseSensitive

bool

Gets or sets a value indicating whether this filter descriptor is case sensitive.

public bool IsCaseSensitive { get; set; }

Property Value:

true if the filter descriptor is case sensitive; otherwise, false. The default value is true.

Operator

FilterOperator

Gets or sets the filter operator.

public FilterOperator Operator { get; set; }

Property Value:

The filter operator.

UnsetValue

object

Specifies a static value that is used by the filtering system rather than null to indicate that a OperatorValueFilterDescriptorBase.Value is not set and thus the filter is inactive.

public static object UnsetValue { get; }

Property Value:

An unset value.

Assign this value to a OperatorValueFilterDescriptorBase.Value if you want to mark it as inactive.

Value

object

Gets or sets the target filter value.

public object Value { get; set; }

Property Value:
