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?

Here's a working example:

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.
