CultureInfo

Gets or sets the culture of the filter descriptor.

public bool IsCaseSensitive { get; set; }

Property Value

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

Operator

Gets or sets the filter operator.

Declaration

public FilterOperator Operator { get; set; }

Property Value

FilterOperator The filter operator.

UnsetValue

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.

Declaration

Property Value

System.Object An unset value.

Remarks

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

Value
