Only 1 method has code in it.

afterrowcolchange method

LPARAMETERS nColIndex
IF NOT DODEFAULT()
	RETURN .F.
ENDIF 
thisform.populate_detail()

If I do set step and debug it, when the afterrowcolchange event fires after I have selected a different row in the grid, the value for the 1st field in
the grid still contains the original row information, not the new selected row information.
