VDF16.1

When the user records the datas in a grid, I like that he comes back to the first column in the next line.
In dbgrid, I had such a code
Code:
      Procedure Down_Row
          Forward Send Down_row // move down 1 row
          if (champs.recnum = 0) Set Current_Item to (Base_Item(self)) // Make crnt item 0
      End_Procedure
How can I do the same in a cDbCJGrid ?

In the help it's said that the procedure "MoveDownRow" bring the focus to the first column enterable in that row but it seems that it's not correct.

I have written this procedure (where oTests_code11 is the first cDbCJGridColumn) but it doesn't work.
Code:
        Procedure MoveDownRow
            Forward Send MoveDownRow
            Send Activate to oTests_code11
        End_Procedure
Thanks
