This event enables you to check conditions of the page request, such as whether the page is being loaded in response to a postback. You can also check the values of profile properties.

The event enables you to set values that are used later in the page life cycle. You can dynamically set a master page or a theme for the requested page, and create dynamic controls.

For more information about how the Page.PreInit event fits into the ASP.NET life cycle, see Introduction to the ASP.NET Page Life Cycle.
