Replace all asp:DropDownList and asp:ListBox controls that are being
used in your ASP.NET applications to lookup the database information with infinitely
scalable and efficient Database Lookups for ASP.NET and AJAX 3.5.

DataValueField="ProductID" DataTextField="ProductName" />

<aquarium:DataViewLookup ID="ProductsLookup" runat="server" DataController="Products"
DataValueField="ProductID" DataTextField="ProductName" />
