The key idea in Greg's post is that whenever you are dealing with the data, *always* use the dataProvider(item, property), and never try to go through the visual control (row, column)

That wouldn't work if the datagrid has sortable columns. Even if you tracked
what row was clicked by trapping an event, the row number would no longer
correspond to the data if the column was sorted.... so going through the
dataprovider fails. We need a way to go through the visual control to get at
the data.... and frankly I've been trying to figure that out and it's far more
difficult than it ought to be. Care to give us a solution?

The itemClicked event gives you access to the actual *data* that was
clicked. I'm not sure why you'd need to know its row number. Please also
note that when a user sorts the dg, the dataProvider of the dg will reflect
the sort.
