Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the InvalidateCardField member must not be invoked for these Views. The InvalidateCardField member can only be used with real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
