public event PivotFieldEventHandler FieldExpandedInFieldGroupChanged
Public Event FieldExpandedInFieldGroupChanged As PivotFieldEventHandler
The FieldExpandedInFieldGroupChanged event handler receives an argument of the PivotFieldEventArgs type.
The following properties provide information specific to this event.
Fields can be arranged into groups via the ASPxPivotGrid.Groups property. These fields cannot be separated from each other, and are always moved as a whole via drag and drop.
To get and set the expansion status of fields combined into a group in code, use the PivotGridFieldBase.ExpandedInFieldsGroup property.
When the expansion status of fields is changed via code or by an end-user, the FieldExpandedInFieldGroupChanged event fires. The event's Field parameter specifies the field being expanded/collapsed.
