Fields Popup
RadPivotGrid Fields Popup functionality enables grouping of zone fields in convenient popup which increases the space available for the table holding the pivot data. The feature could be enabled individually for each of the zones under the RadPivotGrid.FieldsPopupSettings property.
The FieldsPopupSettings class exposes four properties:
FilterFieldsMinCount
AggregateFieldsMinCount
ColumnFieldsMinCount
RowFieldsMinCount
Note that any value different from the default zero will force the popup to appear if the count of thefields in the zone is bigger or equal to the specified one.
