When update 2 of
Delphi
2005 comes out one of the additional features of HTML Error Insight (the
squiggly error underlining in the code editor) will include detection of
duplicate tag ID's. This feature will allow the developer detect and correct
duplicate tag ID's without having to run the application and wait for the
ASP.NET runtime to flag
the error for you. There have been numerous other improvements to HTML Error
Insight for Update 2 but I think this is probably the most useful one and
thought it was worth mentioning.
