To show hidden fields, set the PivotFieldListControl.Area property to FieldListArea.All and the FieldListControlBase.IncludeVisibleFields property to false. To show both visible and hidden fields with check boxes that allow end-users to control their visibility, set the FieldListControlBase.IncludeVisibleFields property to true.
You can optionally use the PivotFieldListControl.Orientation property to specify whether field headers are stacked vertically or horizontally. Pass the FieldListOrientation.Auto value to enable PivotGridControl to automatically choose the orientation. In this instance, if the area's width exceeds its height, headers are stacked horizontally; otherwise, they are stacked vertically.
To specify the visibility of various area elements, use the following properties.
