In two words:

<asp:sqldatasource id="CustomersSource"
  selectcommand="SELECT CustomerID, CompanyName, FirstName, LastName FROM SalesLT.Customer"
  connectionstring="<%$ ConnectionStrings:AWLTConnectionString %>" 
  runat="server"/>

<asp:gridview id="CustomersGridView" datasourceid="CustomersSource" autogeneratecolumns="True" 
  runat="server">        
</asp:gridview>
