Currently, it doesn't matter where one doucble clicks in the row, the same form opens up with row specific data to be edited. I'd like to fix it up so that if the enduser specifically double clicks on the icon in the particular column, that the form opens up, but goes directly to a different page in the pageframe. I still want the grid row to be uneditable, and for the cells in the grid to be unselectable individually (act like a list box, and highlight the whole row).

in the grid's mousedown event you can detect the mouse position ; then using the column widths calculate which column was clicked and pass that (via grid's tag property?) to the dblClick event

something like (untested)
LPARAMETERS nButton, nShift, nXCoord, nYCoord
m.lnStartPos = THIS.LEFT
FOR nCol=1 TO THIS.COLUMNCOUNT
	m.lnStartPos = m.lnStartPos+ THIS.COLUMNS(nCol).WIDTH
	IF nXCoord < m.lnStartPos
		EXIT
	ENDIF
NEXT i
THIS.TAG = STR(nCol)  && where dblClick() can find it
