Remarks
The FieldValueExpanded event is raised after a field value has been expanded by an end user. Note that it provides a notification only and you cannot cancel the action. To control whether individual field values can be expanded, handle the PivotGridControl.FieldValueExpanding event instead.
NOTE
The PivotGridControl.FieldValueCollapsed and FieldValueExpanded events raise when a single value is expanded or collapsed and do not fire when end users expand / collapse fields by using the built-in context menu. To be notified when an end-user clicks the "Expand All" or "Collapse All" menu items, use the PivotGridControl.PopupMenuShowing event. In this case, you can use the PivotContextMenuIds class to identify menu items.
