? maybe this way (on Dataset)

procedure TForm1.Table1BeforeInsert(DataSet: TDataSet);
begin
  abort;
end;

procedure TForm1.Table1BeforeDelete(DataSet: TDataSet);
begin
  abort;
end;

you could it also combine into one method
assigned by both events

appendix to above

you must disable the dgConfirmDelete in the dbgrid.option
to get rid of the ConfirmDeleteMessageBox

easiest way is to place abort; in your Table/Query BeforeDelete and BeforeInsert events.

procedure Table1BeforeInsert(DataSet: TDataSet);
begin
  // yoy can optionally check for some flag if you need append/delete record in program
  // if UserEditMode then
  abort;
end;

to prevent for Delete/Insert only within Grid you must catch pressed keys in OnKeyDown event and that is more complex as, for example, TAB key produces row insertion if it is pressed on last editable column in last row etc.

wbr, mo.
