One of the best parts of jQuery is it’s robost CSS style element selector. However, ASP.NET screws up our element IDs.  John Sheehan did some cool research and created a custom selector to select items based on the end of of the item ID.

6. The BlockUI Plugin

BlockUI is handy for preventing extra button clicks on elements you’re updating with a web service or even inside an UpdatePanel if you’re still into that kind of thing…  :)
