--or--
introduce any new method (ValidateFieldData ? ;-))) and let tdatsset
descendants use it:
{$IFDEF FPC}
ValidateFieldData(Field: TField; Buffer: Pointer);
{$ENDIF}
--or--
some smarter solution ?
The whole code, which is repeated (and can be put in one place) is:
if not (State in [dsEdit, dsInsert, dsFilter, dsCalcFields]) then
begin
DatabaseErrorFmt(SNotEditing,[Name],self);
exit;
end;
if (Field.FieldNo>0) and not (State in [dsSetKey, dsFilter]) then
begin
if ReadOnly then DatabaseErrorFmt(SReadOnlyField,
[Field.DisplayName], Self);
Field.Validate(Buffer);
end;
Laco.
