To get started create a new web site called webNorthWindDataControls and copy the web site named WebNorthWind. Add a web form to your application named DataControls. Right-click on DataControls.aspx in the Solution explorer, and make it the start page for your application.

Switch to Design view and drag a DataList control onto Datacontrols.aspx. Notice that the smart tag opens, offering you an opportunity to choose a data source. Choose New Data Source and for this exercise, choose SQL Database, naming the new data source DataListCustomerDataSources. Use your existing connection to Northwind, and specify that you want all the fields in the Customers table.
