I am trying to work out a way to use Dependency Injection with ASP.NET controls.

I have got lots of controls that create repositories directly, and use those to access and bind to data etc.

I am looking for a pattern where I can pass repositories to the controls externally (IoC), so my controls remain unaware of how repositories are constructed and where they come from etc.

I would prefer not to have a dependency on the IoC container from my controls, therefore I just want to be able to construct the controls with constructor or property injection.

(And just to complicate things, these controls are being constructed and placed on the page by a CMS at runtime!)

Any thoughts?
