Custom Libraries

If your application has a custom library compiled as a DLL, all of this code can be embedded here, and a reference added in the web application. Alternatively, rather than creating an interface for the user control, a custom user control class can be created by defining a class that inherits from System.Web.UI.UserControl.

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.
Cheers
