Datagrid help - change value in form

[Gerry Orkin]

Hi all

I've only just got my head around datagrids (and I'm loving them), but I can't find an easy way to update a field in a specific row in a form. I know which row needs to change, but I don't have that row highlighted. As far as I can see all the examples in the documentation assume you have the row highlighted.

Your help appreciated :)

Gerry
