• Summary

The ObjectDataSource control enables you to bind DataBound controls such as the GridView, DetailsView, and FormView controls to a component. You can use the ObjectDataSource control to easily build multi-tier applications with the ASP.NET Framework. Unlike the SqlDataSource control, which mixes data access logic in the User Interface Layer, the ObjectDataSource control enables you to cleanly separate your User Interface Layer from your Business Logic and Data Access Layers.

In this chapter, you learn how to use the ObjectDataSource control to represent different types of objects. For example, you learn how to use the ObjectDataSource control with components that represent database data. You also learn how to use the ObjectDataSource control to represent different types of method parameters.

In the course of this chapter, we tackle a number of advanced topics. For example, you learn how to page, sort, and filter database records represented by the ObjectDataSource control. You learn how to page and sort through large database tables efficiently.

In the final section of this chapter, you learn how to extend the ObjectDataSource control to represent specialized data sources. You also learn how to extend the ObjectDataSource control with custom parameters.
