To do:

1. In DBApp2 change the query so that more than one record is returned 
(e.g., select * from products where [category name]='Beverages'), click on the columns of the grid

2. Play with the properties of the grid control (page 559 of book)

3. Modify the application in the following ways:
a. In the drop down box show order ids and when user selects order, show order details for that order
b. In the drop down box show categories and when user select category, show products in that category
c. In the drop down box show customers and when user selects customer, show orderids for that customer in
	another dropdown box and when user selects orderid, show details of that order in the grid view
d. Implement all of this using visual studio
