The AutoFilterControl and FilterRow are two different controls. While you could set the DataGridCollectionViewSource’s DistinctValuesConstraint property to “Filtered”, to display a column’s DistinctValues which only matches those filters which are applied on AutoFilterControl of other columns. There is no such property which allow to modify the AutoFilterControl’s distinct values depending on the applied values on the FilterRow.
