Hello everyone. I am a VS2008 developer. I just dug into DNN. I need alot of what it has in the core but have to integrate several other custom dynamic pages in to DNN. I have seen the videos, and Michael Washington's great http://www.adefwebserver.com , site and have successfully built a module based on the suggested best practices using the API. 

The site needs to have several dynamic pages that use drag and drop from grid to grid, some work flow or step through processes, and some other cool ajax functions. This functionality is built on several aspx pages already ,and is working fine outside of DNN. I know that I can build user controls and integrate these pages in to DNN as modules.  Now my question:

In general, do these higher level client side type functions work well and without problems when they are integrated in to a module for DNN or are there tons of issues that have to be worked out or ... maybe something in between?   I am just wondering what I am up against with this and if this is a workable idea?  Is there a better way to do this than user controls in to a module.   Thanks for your answer!
