This situation is not practical for every situation. Rather, you may implement it for a small set of features, such as exposing certain properties reused throughout the application, exposing a user control that contains a header or other important information.

However, there may be times when you need to implement something similar to this because of a required duplication, and therefore may be a requirement. Especially when a user control needs to access certain page properties that may be constant throughout the application, a custom page class is useful. This is because a user control cannot convert its Page property to the rightful type of the code-behind page (especially when a user control is used in many pages), but it can convert it to the type of the custom page class.

Title: Use events

At my work we implemented a event system that makes you able to register an event(in one control) and listen for that event (in another control). This way you can also send over objects and use them. And you never have to involve the page. You just drop the controls on what page you like and they know how to talk to each other.

When this has been set up once, using it is extreamly easy. This is something i would like to have by default in the framework..

As a rule we try to use this sparingly but we have never had any speed/memory problems at all with this approach!

Great Brain, that actually confirm my way I'm currently using.
I faced the issue that I needed 2 user controls to be able to communicate with each others through the Page. And the way you present here is also good for such cases.
