In sp 2007, I have used jquery to do the cascade. But now I hear sp 2010 provides cascaded lookup. I have 3 level to drill down (Country > State > City). Is/are there any good instruction on how to implement cascaded lookup? All the lists have been created with parent-child relation.

Have a look at the $().SPServices.SPCascadeDropdowns function within SPServices.

@That's Marc jQuery stuff right? which I used in SP 2007. Now that microsoft has a way to implement cascaded lookup i rather use that. I am tired of maintaining codeplex code + all the 3rd party stuff we have. – Roxanne May 19 '11 at 14:27
CascadeDropdowns works in both versions. You shouldn't have to change anything if you've already implemented it in 2007. – PirateEric May 19 '11 at 14:33
Roxanne, The relational behavior you're describing in 2010 is limited to cascading delete, so if I delete my parent record I can set it up to automatically remove all of the child records of that record. You also have the ability to bring in multiple fields from a lookup, but it's not a cascade. The only way to cascade in a form is through UI changes such as using SPServices, you'd be doing the same thing as you did in 2007. There's some "for purchase" bolt-ons that make it "easier", but SPServices is most likely still your best bet. – webdes03 May 19 '11 at 14:34
Also (was out of characters in my previous comment), there's a good blog post here which explains the SP2010 relational stuff pretty well: zimmergren.net/archive/2010/01/05/… – webdes03 May 19 '11 at 14:35
