Representation of an ItemFilter. The item filter has the ability to filter on a single value in the column that is applies on. The value that is being filtered on is given by Value.

In addition to the distinct values in the DataColumnReference, the Item Filter can filter on the special values given by the ItemFiltering enumeration. The All value is the default value of an Item Filter. The None value is the last value in an Item Filter. The Empty value is only used when the filter column contains empty values.
