c#: handling mouse events with ms chart

i am displaying a line graph on an ms chart using VS2008 c开发者_运维百科# professional

what i am trying to do is when the user clicks on a datapoint, it will display the entire ROW in the database for that point.

how can i

1. handle the click event
2. display the row for that particular point?

this is just an example, of course if you need to access the DB you need an access logic and so on... but the idea is basically the same.
