My department has recently upgraded a .NET 1.1 Framework web page that has a windows control on one if its aspx web pages to .NET 2.0 Framework. The windows control dll was copied into the aspx web page root level and put in classid in the aspx html source code to reference the windows control. Data is passed back and forth between the windows control and the vb code behind using properties. The windows control has buttons on it and has its own vb code behind. I need to walk through the windows control vb code behind logic along with the aspx web vb code behind. I have not been successful on performing this task. Any suggestions on how to best to this?
