Mapping ?

I have an Asp.Net form with a DBGrid on it. Each time I click a row on the
Grid, I would like to map (copy) its fields on the selected row to the form
fields (also on the same Asp.Net page). I also like to map the form fields
back to the same selected row on the Grid if the user makes changes to any
fields on the form.
Thanks for your help,
JohnThis must be done at client, not server. I guess Java Script is playing the
role here
Thanks
John
