Page Loading issue - Sitefinity - Front- & Back-End Development

I have created a customer widget for displaying news based off of a similar 3.7 custom code. After spending a lot of time I have the widget working, or so I think. I can load it onto a page, and view the page no problem. However once I publish the page, then go back to edit the same page, it never finishes loading. All I get is the animation at the top of the page going back and forth. There are no errors in the log, and I get no exceptions from .net.
Here is my code, sorry for the length:

Forget it. Of all things it was a very minor formatting issue on the ascx that was causing the issue.
