Gets a list of objects stored in the page context.
Assembly: System.Web (in System.Web.dll)
Use the property to store objects with the same lifetime as the page request. This property is read-only; however, you can add objects to the IDictionary object it returns.
Objects added to the property are available throughout the lifetime of the page, so you can add objects to the property in events early in the page life cycle and access those objects in later events.
