Sorry for newbie question, but here goes.

ex.
on form1 there is listbox1 and datagridview1

I have tables for dbo.category and dbo.issues.

in listbox1, is the listing from dbo.category.

what I want to do, is this:
click on an item in listbox1, say that is "APPLE"

I want that click event to take the selecteditem,qu ery the dbo.issues and find every record...
