The Scrollable Area Problem
The Scrollable Area Problem by Robert Mc Laws.
Well Robert, if you remove the part about yourself and how marvelous you are, sounds cool ! ;-))
I am not sure by the way you should put a trademark on this. Go on, open source, give it for free. Because it's seem to be part of Whidbey anyway.
Other thing: I mentioned in a post another thing I use, an HTC file to maintain the header. I know it's only for IE, but I am actually looking at a way to keep the Javascript code of this nice tip.
Also the code you wrote has already been published last month by Dino Esposito in MSDN magazine (or ASP.Net Pro ?!?).
It's a two part article, and in the first part he give an example with exactly the right code. In the next part he promised to give the code for an unlimited number of columns. If somebody is interested by the HTC code, let me know ;-)
