TBaseDataSetAdapterField.ImplUpdateValue Method

Provides the underlying implementation for the UpdateValue method.

Pascal
procedure ImplUpdateValue(AActionRequest: IActionRequest; AFieldIndex: Integer); virtual;
C++
virtual __fastcall ImplUpdateValue(IActionRequest AActionRequest, int AFieldIndex);

The UpdateValue method calls ImplUpdateValue to respond when the user assigns a new value to this field. 

AActionRequest is interface of the action request object. ImplUpdateValue can use this interface to obtain information about the current request (such as the value the user assigned to this field). 

AFieldIndex is the index of this field in the set of field values that AActionRequest maintains. 

ImplUpdateValue does nothing. Descendant classes that support field updates override this method to assign a new value to the associated database field.
