Here is my current status on that grid component. Current details, download links, screenshots, etc, are available on my site, specifically at http://www.overminddl1.com/forum/index.php/topic,442.msg2141.html.
Helpful critisizim(sp?) is appreciated. Do read the post before you download and note that it is a very early, ugly, version. Will make an example program should I get some free time, but I do have some example code up.
If you make changes that I might find in any way useful, please submit them to me so I can incorporate useful changes for everyone.
