(I am using VS 2003).One can drag a datadapter object onto a Windows form and thus configure it at design time via the wizard. I wish to create a separate class for business logic and have my dataadapter instantiated in that class, instead of on the windows form. Is there a way to do this? (One can instantiate a dataadapter and configure it in code, but I wish to do this in a design environment and with the configure datasource wizard. The toolbox associated with a simple class object is empty, unlike a form toolbox. Please advise.
