Just a heads-up ... I found that many of my aspx pages would not open in the VS2010 designer due to all child controls appearing as red blocks with "object reference not set" null errors. It seems that VS2010 is calling the Init method when in the designer, this might be a bug, but it seems to be revealed by my old original code that was generated back in VS2005 (or maybe even VS2003!). Back then it would generate a #region with override OnInit and add the button click handlers. I debug attached a second VS2010 and it showed that the button control reference was null in this OnInit override. I had to move all of the +=Click add handler lines into the Page_Load method and it all comes good.
