Note: Field's that have a DataType that implements the System.Collections.IEnumerable interface are expandable by default. However, any Field can be made expandable by setting its IsExpandable property to true. Expandable fields have associated ExpandableFieldRecords and ExpandableFieldRecordPresenters to represent them in the UI. When one of these is expanded its nested content will contain either a RecordListControl if its value implements the IEnumerable interface and is not a string. All other data types including string will display an ExpandedCellPresenter.
Note: If this property is left to its default setting of null then IsExpandableResolved will return true for Fields whose DataType implements IEnumerable. All other data types will return false by default.
