how would you guys create a dynamic layout in ASP.NET MVC 2 where admins could select widgets to display, arrange them, disable, move them etc.? I mean a flexible layout that can be changed via the admin panel without having to touch the code. Here I thought about defining and storing layout widgets paths in a db. Later I could associate these widgets with routes (in db). For each request (controller, action) I would fetch the layout among with associated widgets and output them recursively. Probably I could user RenderAction and PartialViews for that.
Is my direction correct or should I focus on some other technique?
Thanks,

Rob Conery did a similar thing with his Kona rewrite. He was able to make regions in the page, and then associate widgets to those regions.
There are two approaches that come to mind:
1.) The first is you load all your widgets in the controller action and the content they hold. Then send all this information of widgets (in a model) up to your view and do your filtering there. This preserves your separation between the view and the controller. You’ll probably want to create a helper method:
One note on the first approach. You’ll probably want some kind of naming convention for your widgets, so you can find their partial view more easily.
2.) Another approach is to use RenderAction and call a “RegionController” that you can pass a region name to. Passing the region name will trigger a query for all widgets that fall within that specific region.
I personally would do the first approach, but I don’t see a problem with the second approach other than the cries from the purists.
