> So in my UI the devices could potentially be dragged and dropped between rooms. I am sort of struggling in my imagination how I actually track which devices though are dragged and dropped to each room if you see what I mean, after studying your example.

Don't think of Drag_Text as just text. Use it to pass between objects an index to data in a DB or data structures, etc.

> Another problem I have is that the App_Data type is generated at compile time when I want really to be able to populate this or even possible update it during the use of the web app.

I don't think any tutorials talk about it yet, but any control created on the heap and marked as dynamic is cleaned up when a view finalizes, so its not per se needed to use the App_Data.

There are also other ways of working such as the AdaBlog in /demo that uses an MVC static page model and again no need for App_Data.

Actually pointers is your answer :)
