Specifies whether or not filtering is active for a dataset.
property Filtered: Boolean;
__property Boolean Filtered;
Check Filtered to determine whether or not dataset filtering is in effect. If Filtered is true, then filtering is active. To apply filter conditions specified in the Filter property or the OnFilterRecord event handler, set Filtered to true. Because unidirectional datasets do not support filters, when you set Filtered to true on a unidirectional dataset, it raises an exception.
