Dave,
Activecolumn returns the columnorder not actual columns collection index. A slight modification :

oX= THISFORM.ACTIVECONTROL
IF oX.BASECLASS = "Grid"
  nn= oX.ACTIVECOLUMN
  IF BETWEEN(m.nn, 1, oX.COLUMNCOUNT)
    for ix = 1 to ox.Columncount
      if oX.COLUMNS(ix).Columnorder = m.nn
	oX= EVALUATE("oX.Columns(m.ix)." + oX.COLUMNS(m.ix).CURRENTCONTROL)
      endif
    endfor
  ELSE
    ox= .F.  && or whatever step you wish to take :-)
  ENDIF
ENDIF

>>I wrote a routine to return the active control and its full containership hierarchy. It seems to work fine, EXCEPT that activecontrol always returns the name of the grid, not the text box, or other control that has the focus within a grid. It seems to work fine on all other controls except the grid.
>>
>>The text box or other controls in the grid are editable, i can type in them no problem. They definitely have focus at the time I call them. At first I tried this with a grid that had a container with a text box and command button in it - when that didn't work I simplified it - and just called it from a simple grid with the default text box control in the column.

>>This is a real problem, because it will almost always be called when the focus is in a text box in a grid! Any suggestions would be greatly appreciated!!!
