>>>Hi,
>>>
>>>I have a grid bound to a cursor. I need to track which rows of the cursor user "touched" (made changes). So I am going to add a column CHANGED L to the cursor. Then when user makes any change in any column of the grid row I will set the value of CHANGED to .T.

Yes and it will change the corresponding row. In other words, once you clicked and started to change, it will be that ROW. If you just clicked, then it is not known.
If it's not broken, fix it until it is.
