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 Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.
