No, neither methods need to be in your code-behind. They can exist in a business object, or anywhere else. ObjectDataSource should use the type specified in TypeName (so you could set it to the fully qualified type name). It will use reflection to find the methods specified in SelectMethod and SelectCountMethod that have the same parameters as specified in the SelectParameters collection (your method parameter names have to match the names provided in this collection).
