  • A guide to ObjectDataSource control11/17/2006 4:38:00 AM. One of the best new features of the forthcoming ASP.NET 2.0 will be the ObjectDataSource control. However, as I found out in my experimentation what seems like a simple control has some complex behaviours to master to get it working properly. If (like me) you have an existing data access layer you may have to make changes to be able to use ObjectDataSource.
