I used parent child drop down from Codeplex they worked really very well until when we moved the site to a new web application after upgraded the web applications to 2010.
 
We installed the parent child controls again in sharepoint 2010 but the problem is moved the site to new web application, is they a way to change the url in parent child control to point to the new web application
