I am really confused.
I followed this tutorial:
http://msdn.microsoft.com/en-us/library/ee707362%28v=vs.91%29.aspx[^]
I know how to add but now i don't know how to add method , which get data from 2 table not from a table.
Because the result i want have properties from 2 tables.
A for example:

Customer:customerID,customerName
Order:OrderID,CustomerID,OrderDate
I want result:
CustomerID,CustomerName,Orderdate.
But i am confused because the class for customer and order are different.
I don't know which type of result i should return so that i can binding into my gridview.
Someone please give me tip.
Thank in advance.

because the result is the one come from 2 table. So i really don't know what type of it.
If it's Customer type, OrderDate don't have. and same for Order.
