TCustomDataSetAdapterImageField Class

TCustomDataSetAdapterImageField is the base class for adapter field objects that represent a graphic field from a database.

Pascal
C++
class TCustomDataSetAdapterImageField : public TBaseDataSetAdapterImageField, public IGetAdapterImage, public IGetAdapterItemRequestParams, public IAdapterRequestHandler, public IWebImageHREF;

TCustomDataSetAdapterImageField is the base class for all adapter field objects that represent graphics fields from a dataset (TGraphicField objects). TCustomDataSetAdapterImageField descendants are included as the fields of a dataset adapter (TDataSetAdapter) when that dataset adapter represents a database that includes graphics fields. TCustomDataSetAdapterImageField represents a single field from a database table, and enables server-side script to refer to or update that field's value. 

Do not use TCustomDataSetAdapterImageField directly: it is intended only as a base class. Instead, use a TCustomDataSetAdapterImageField descendant such as TDataSetAdapterImageField, which publishes several of the properties and events that you can use at design time to bind the adapter field to the corresponding dataset field.
