Hi all, it's me again.
Currently I'm developing web-based information system using Microsoft Visual Studio 2010 Professional with VB language. I was doing fine with my work until several days ago. The web pages I've created work normally, but what makes me puzzled is that all user controls in the web page aren't populated in the General dropdownlist (upper left of the code behind window). It only populates the class name of the page.:?:
Where actually is the setting menu for that dropdownlist?
Here I attached a bit of printscreen of my problem.
I will really appreciate your help. Thanks a lot.:)
