Life Cycle of an ASP.NET Mobile Web Page

The life cycle of a Microsoft ASP.NET mobile Web page and its controls is similar to the life cycle of a standard ASP.NET Web page. The following section describes similarities and differences between them. For more information about the life cycle of an ASP.NET Web page, see ASP.NET Life Cycle.

NoteNote

The life cycle of an ASP.NET mobile control is the same as the life cycle of a mobile Web page.

For information about the life cycle and interaction between controls and their associated adapters, see Control and Adapter Interaction, Types of Adapters, and Adapter Interaction with ASP.NET.

The following table lists life-cycle stages of a mobile Web page and information about its controls. This information primarily describes the differences in the life cycle of a mobile Web page or mobile control from those described for a non-mobile ASP.NET page. For complete documentation about the ASP.NET life-cycle stages, see ASP.NET Life Cycle.
