        _dp.FieldSettings.AllowRecordFiltering = True

        ' You can use FilterClearButtonLocation to specify whether to display filter clear
        ' button in record selector and/or cells. Note that the filter clear button is 
        ' displayed only if there are active filters. Therefore you must select some filter
        ' criteria in the filter cell to display the filter clear button.
        _dp.FieldLayoutSettings.FilterClearButtonLocation = FilterClearButtonLocation.RecordSelectorAndFilterCell

        ' You can use the FieldSettings' FilterClearButtonVisibility to override filter 
        ' clear button visibility on a specific field, in this case the 'Country' field.
        _dp.FieldLayouts(0).Fields("Country").Settings.FilterClearButtonVisibility = Visibility.Collapsed

    End Sub
