Service Pack 1 of .NET 3.5 introduced ADO.NET EntityDataSource control which can be employed in web applications that use the ADO.NET Entity Framework. EntityDataSource control provides data binding based on Entity Data Model (EDM). EDM presents data as sets of entities and the relationships among entities. EDM is used by Entity Framework in object-relational mapping (ORM or O/RM or O/R mapping) and in other technologies such as ADO.NET Data Services. EntityDataSource control manages create, read, update and delete operations on ASPX pages. It may be employed by all known controls with data binding such as ListView, DropDownList, etc. EntityDataSource can also get values for query parameter from controls, query strings, cookies and other parameter objects. For more information and how to employ this control, you may refer to the following books:
