How they deal with form submitting without affecting the parent controller and routing?
Also if I have a plenty of subcontrollers on page do I have to use this?

public ActionResult Index(MySubController1 one, MySubController2 two, MySubController3 three, …) {
….
}

I don’t get why all these tricks just to delay the subcontroller invocation until the view is rendered. Why not just invoke another ’subcontroller’ directly from the parent controller, and put the rendering result to the ViewData, which will be displyed literaaly on the view.
Using the trick used in this post, there are too much magic and convention, and that 1 subcontroller can only have 1 action.
I just don’t understand why we need to insist to let the view invoke the other controller. Why not just let controller call the other controller directly? Afterall, isnt it more MVC to get do it this way?

I prefer the way it’s done in MVC FUtures:
<%= Html.RenderAction(actionName,params) %>

It seems more effective and more concise than your solution, and has the same drawback: you’re calling a controller from within a view …
Unit testing with mocking may be easy if RenderAction uses a factory to create the ControllerClass.

[...] Option 2 is conceptually much simpler and enables simpler code, though at runtime there are more moving parts. It’s more like having a collection of genuinely independent widgets. This is what you get with <%= Html.RenderAction(…) %> (which is sadly relegated to the MVC Futures assembly and has been left with some technical problems), and also with MvcContrib’s new idea of subcontrollers.

I think this was a very clever solution. It also shows that the model binder is being hacked like crazy (or “trick” as you called it ) to do things it was not meant to do (judging by its name.)
Would it work if the subcontrollers were constructor-injected instead of actionParameter-injected ? Similar conventions could be set to populate the viewdata from controller properties.
