How can I hide aggregators and column descriptors areas (see attached image)?
So far I found what I can execute the following code
pivotGrid.PivotGridElement.AggregateDescriptorsArea.Visibility = ElementVisibility.Collapsed;
pivotGrid.PivotGridElement.ColumnDescriptorsArea.Visibility = ElementVisibility.Collapsed;
and these areas will not be visible, but their placeholder still be displayed, i.e. empty rectangle at the top of the pivot grid. How can I completely collapse these areas?
