Hi Rex,

>How can I tell in the Grid.BeforeRowColChange method if I am trying to change the Row or the Column in the grid?

If you can wait untill AfterColRowChange its easier (save the column number, save it in a property and compare it too tnColIndex), but the only way I know how to do it in Before.. is like this:

LPARAMETERS nColIndex

if inlist(lastkey(), 5, 24)
	debugout 'Row Changed'
else
	debugout 'Col Changed'
endif

Now, this will not tell you accuratly when you choose a cell with the mouse, or programmatically. You should be able to trap that though, Good Luck!
