Chris - Thanks for your quick response and also thank you very much for the template and clear instructions provided in your blog. It was really helpful for getting me started.
I am not familiar with the DNN config so I will have to look at that. I was just surprised that it added a web.config file in the root of my project when it wasn’t the application root. Here is what I had to put in the web.config file (located in the DNN application root) to make the ASPxGridView work. I also had to copy some DLL files into the bin directory.
