I was trying to find a way to do Cascading Drop Down Lists in SharePoint, and I came across this interesting article.

It shows you how to do it. If you have any problems, let me know.

Hi
Cascading DDL's works perfectly in single environments. At our company we work om DEV, QA, and PROD servers and when a backup and restore is done, the new item form cannot be accessed because it is looking for the previous environments URL when the Cascading DDLs were created. Is there a way of refreshing the lookup URL after a backup and restore is done?
Any help would be appreciated.
Thanx alot,

Hi Fadi,
I managed to create a column and had it bind to parent drop down list.
However, I received this error
when I opened my page that uses this column.
[NullReferenceException: Object reference not set to an instance of an object.]

I have posted a Blog on Cascading Dropdown here. It allows unlimitted siblings
