Does anyone know how to make the focused item on a TStringGrid move, say one item down, when the user changes it's value? /like in MS Excel worksheet/
...perhaps onChange event would do the job, but it's not implemented in TStringGrid....
..any ideas?

In Excel, you still have to tab or arrow to the next item.  TStringGrid supports this as part of the Options properties goEditing and goTabs

Ya, but in Excel u dont have to navigate with the down key /by default/ to move to the next down position -> when a field is JUST edited the focused one is automaticaly moved down by one position...thats what I intend to do in C++ Builder....

I'm guessing you're talking about after you hit the enter key.  If so, the following should help get you started.  Place this code in the TStringGrid KeyPress event handler:

void __fastcall TForm1::StringGrid1KeyPress(TObject *Sender, char &Key)
{
  if (StringGrid1->EditorMode && Key == VK_RETURN){
    if (StringGrid1->Row < StringGrid1->RowCount - 1)
      StringGrid1->Row = StringGrid1->Row + 1;
    else{
      if(StringGrid1->Col<StringGrid1->ColCount-1){
        StringGrid1->Row = StringGrid1->FixedRows;
        StringGrid1->Col = StringGrid1->Col + 1;
      }
      else{
        StringGrid1->Row=StringGrid1->FixedRows;
        StringGrid1->Col=StringGrid1->FixedCols;
      }
    }
  }
}
