Still no data :(. Also seems like a weird bug when I go to "edit columns" after to add/change some they all disappear. I'm using VS 2010 SP1. I tried reinstalling Dev Craft Complete, no luck. Now i'm trying to install VS 2013 with Dev Craft Complete to see if the problem remains. If you have any ideas on how to fix this possibility "corrupt" dev craft situation, please let me know. Thanks for your help so far! You guys, as always provide great support! Which is why I love your products!

Hi Logan,

As I did not manage to observe the described issue using the provided code I will ask you to provide a screencast video where we can see this problem. Also confirm that you have only configured the TreeList declaratively and there is no related code behind in your project. If you have any code there, please share it with us.

Additionally, you mentioned that most probably the problem is related to the edit columns, however in the code you provided there is no edit column. Can you please confirm that you have observed the same behavior when you run the project I sent you? If not please specify what is the difference in your application, provide the whole code and step by step instructions how to replicate it on our side.
